Diagrams of small cloud systems.
Design walkthroughs of automations, DevOps, and infrastructure — each post centered on a diagram. Open to builds, collabs, and design reviews. By Allan Niñal.
All series · newest first
-
Pension enrolment assessor
Assesses every worker in every pay period rather than once at the start, keeps each deadline tied to the date the duty actually arose, and reads what staff write about the pension without ever being the one who opts them out.
-
CIS deduction checker
Reads every subcontractor invoice for the labour, the materials and the VAT wording, takes the deduction from the right base at the right rate, and keeps the evidence behind the materials figure -- because when that figure is wrong, it is the contractor HMRC looks to for the difference.
-
Age check logger
Joins the till's age prompts to the refusals book and reads them as a rate, per person and per shift -- because a store that almost never refuses anybody is not a store with unusually well-behaved customers.
-
Restricted fund tracker
Turns every grant agreement into rules with dates on them, charges each cost to the fund that is actually allowed to pay for it, and notices a restricted fund going below zero the week it happens -- not at year end, when the only question left is who agreed to it.
-
Shelf price checker
Reads every shelf-edge label from a phone photo, checks it against what the till would have charged at that moment, and puts the labels that promise less than the till takes at the top of the morning's list -- because one direction of wrong is a legal problem and the other is only money.
-
Payout reconciler
Takes each lump sum a payment provider drops into the bank and splits it back into what was sold, refunded, disputed, charged and held back -- then keeps a running account of what every provider still owes you, and checks it against the provider's own figure.
-
Packaging data reporter
Works out which packaging is legally yours to report, what each item weighs when nobody can weigh 3,000 of them, and whether it ends up in a household bin or a trade one -- because only one of those two answers carries a fee.
-
Late payment interest claimer
Works out the day each commercial invoice actually became late, the interest rate that was fixed on it at that moment, and the fixed sum owed on top -- then keeps the whole calculation in a shape you can put in front of the customer, or quietly never send.
-
Holiday accrual tracker
Works out how much paid holiday every worker has actually accrued when the hours are irregular, keeps the balance moving as leave is booked and carried over, and can say on any date what the business owes if that person walks out of it.
-
Gift Aid claimer
Works out which donations you can actually claim Gift Aid on, which ones only qualify under the small-donations scheme, and which ones are worth nothing because nobody holds the paperwork -- and keeps the evidence in a shape that survives an audit four years later.
-
Product recall tracer
Turns a recall notice into three lists -- what is still on your shelves, who you can actually name as having bought it, and what you can prove to an inspector -- and makes the difference between pulling sixty units and pulling four thousand.
-
Card fee auditor
Works out what you actually pay to take a card payment, finds the transactions that cost four times what they should have, separates the fees your provider controls from the ones they do not, and gives you the two numbers you need before anybody quotes you a better rate.
-
Waste collection verifier
Counts the collections you actually got against the ones you are paying for, proves a missed lift at the moment it is missed, checks the invoice against the contract line by line, and tells you when your bins are the wrong size -- which is where the real money is.
-
Lost property matcher
Logs a found item in ninety seconds, matches a vague claim against it without ever showing the claimant what you have, gets it back to the right person, and disposes of the rest on a policy instead of when the cupboard overflows.
-
Rebate claim tracker
Turns supplier rebate agreements into rules, measures your actual buying against them as it happens, and claims before the window shuts -- because a rebate you earned and did not claim is the cheapest money you will ever fail to collect.
-
Credit limit reviewer
Sets a trade credit limit from the application and the filed accounts, then keeps it honest by watching how the customer actually pays -- because the limit that was right in March is the one that loses you eleven thousand pounds in November.
-
Incident postmortem collector
Captures the timeline while it is still recoverable, resists the urge to name one root cause, tracks the actions that come out of it, and makes old postmortems findable -- because the value is entirely in the reading, and nobody reads them.
-
Asset register keeper
Keeps a record of what the business owns that is still true a year later -- which means solving disposal rather than acquisition, because every register drifts in the same direction and for the same reason.
-
Parking permit issuer
Issues more permits than there are spaces, on purpose, and works out the right ratio from what actually happens -- because the hard parts of parking are the allocation rule and the enforcement, and neither of them is a technical problem.
-
Visitor check-in logger
Keeps an accurate list of who is in the building, which is a fire safety question rather than a security one -- and which means the hard part is not signing people in but getting them signed out.
-
Housekeeping dispatcher
Decides which rooms get cleaned in what order -- balancing arriving guests against walking distance against who has had the difficult rooms all week, and never sending anybody into a room where somebody is still asleep.
-
Allergen checker
Tracks what every ingredient declares, notices when a supplier quietly reformulates something, and is explicit about the large category of things it cannot know -- because a system that says a dish is safe is making a promise it cannot keep.
-
Menu cost calculator
Works out what a dish actually costs to put on a plate -- after trim, after waste, at this week's prices rather than the ones from when the recipe was written, and with portion size treated as the variable it really is.
-
Stock transfer planner
Works out which stock is worth moving between sites -- which is far fewer transfers than the imbalance suggests, because most of them cost more than the imbalance they fix and some of them create a stockout at the other end.
-
Capacity forecaster
Forecasts whether there will be enough people, machines or hours to meet demand -- far enough ahead to do something about it, against the capacity you actually have rather than the one on paper.
-
Utility meter reader
Turns meter readings into numbers you can actually use -- separating estimated bills from real ones, watching what is still running at three in the morning, and adjusting gas for the weather so two winters can be compared at all.
-
Fuel log auditor
Checks fuel records against the vehicles they belong to and finds the discrepancies, most of which turn out to be a mistyped odometer or the wrong van selected at the pump rather than anything worth accusing anybody of.
-
Equipment maintenance scheduler
Schedules servicing against how much a machine has actually been used rather than what month it is, makes deferring a job an explicit recorded decision, and keeps the inspections that cannot be deferred somewhere they cannot be missed.
-
Cold chain monitor
Watches chilled and frozen storage, tells a brief door-open spike apart from a failing compressor, treats missing data as a breach rather than as good news, and never decides on its own what happens to the stock.
-
Delivery exception handler
Notices that a delivery has gone wrong before the customer tells you, which is harder than it sounds because carrier tracking statuses lie in predictable ways and the strongest signal is the absence of one.
-
Damaged goods claimer
Captures the evidence for a damage claim in the two minutes before the packaging goes in the bin, works out which deadline applies, and is honest about which claims are not worth filing.
-
Packing slip checker
Compares what was ordered, what the delivery note claims, and what is actually in the boxes -- and makes recording the difference possible for somebody standing in a doorway holding a phone.
-
Supplier lead time watcher
Measures how long each supplier actually takes rather than how long they say they take, separates their delay from yours, and notices the slow drift that nobody sees until something runs out.
-
Referral payout runner
Works out which referrals have actually been earned, pays them on a stated day under the rules that were published when the referral was made, and shows every person exactly what they were paid for and what was held.
-
Win-back campaigner
Contacts customers who have genuinely stopped buying -- after checking why they stopped, because a third of them left for a reason that a cheerful 'we miss you' email makes considerably worse.
-
Quote comparer
Puts three supplier quotes for the same job side by side, shows what each one leaves out, and refuses to name a winner -- because the cheapest quote is almost always cheapest for a reason nobody has read yet.
-
Lead source attributor
Works out where an enquiry actually came from, keeps the whole path rather than one label, and reports the uncertainty instead of hiding it behind a confident pie chart.
-
Abandoned form recoverer
Notices when somebody got most of the way through an enquiry and stopped, and sends one short message -- but only where they gave an address knowing what it was for, which is a much narrower case than it first appears.
-
Feedback follow-up router
An unhappy score reaches somebody who can do something about it within the hour, with the order and the history attached -- because a survey nobody acts on trains customers not to answer.
-
Data request handler
Recognises a data request the day it arrives, starts the clock, gathers from every system that holds anything, and hands a person a package to review -- rather than somebody finding the email three weeks in.
-
Consent preference keeper
One place that knows what each person agreed to and when, that every sending system asks before it sends, and that can still answer the question two years after somebody asks it.
-
Address verifier
Catches the address that will fail delivery while the customer is still on the page, suggests the correction rather than rejecting them, and never refuses an address a person insists is real.
-
Duplicate contact merger
Finds the four records that are all the same customer, shows a person exactly what would change, and merges only what they confirm -- with every merge reversible for as long as it matters.
-
Access review reporter
Lists who can get into what across every system the business uses, asks one owner per system a short question twice a year, and catches the leaver whose account is still live the week they go.
-
Cost anomaly alerter
Tells you a cloud bill is running away on the day it starts rather than on the first of next month -- with the service, the resource and the change that caused it already worked out.
-
Log anomaly spotter
Collapses millions of log lines into a few hundred shapes, then tells you about the shape that is new or the one that has started happening far more -- rather than about the error you have been ignoring for two years.
-
Form spam filter
Stops the bot submissions without a CAPTCHA, keeps every borderline one where a person can find it, and never silently deletes a real enquiry -- because a lost lead costs more than a hundred spam messages.
-
Uptime status poster
Checks the things customers actually use, from more than one place, and publishes a status page that stays up when your site does not -- because the whole point is being readable during an outage.
-
Search rank reporter
Reports where you actually rank for the queries that bring in work, grouped so that a hundred query rows become six themes, with the pages responsible named.
-
Page speed watcher
Measures the handful of pages that matter, on the same device profile every time, and tells you when a deploy made one slower -- with the resource that caused it named.
-
Broken link reporter
Crawls your own site weekly, checks every link that leaves a page, and reports the ones that are broken in a way that says which page to edit -- ordered by how many people actually hit them.
-
DNS change auditor
Every DNS record is snapshotted hourly, every change is shown as a diff to somebody who can say whether it was meant, and the records that must never move are checked separately.
-
Domain renewal watcher
Every domain the business owns, who it is registered to, when it expires and which card pays for it -- checked weekly, so nothing lapses because a card expired.
-
Safety incident logger
Reporting a near miss takes forty seconds on a phone, the report reaches somebody the same hour, and the ones that repeat get counted -- because the near miss you never hear about is the accident you will.
-
Tip pool splitter
The pool is split by the rule everybody agreed, published the same week, with the arithmetic visible -- so nobody has to trust anybody about their own money.
-
Shift swap broker
Somebody needs Thursday off, the system finds who can actually cover it, and a manager approves one message instead of refereeing a group chat.
-
Training reminder bot
Required training gets assigned when somebody's role says it should, chased when it is not done, and reported as a gap the week it appears rather than at audit.
-
Exit interview collector
The honest answer arrives six weeks after somebody leaves, not on their last afternoon -- so this asks twice, and reports themes across people rather than quotes from one.
-
Offer letter generator
An offer is agreed in a conversation and a correct letter exists ten minutes later -- from your own approved template, with the terms that were actually agreed, and nothing invented.
-
Background check chaser
A new starter's checks -- references, right to work, the disclosure -- get tracked as three separate clocks, each chased at whoever is actually holding it up, so day one is not a surprise.
-
Certification expiry tracker
Every ticket, licence and certificate your people hold gets read once, dated, and chased before it lapses -- so nobody turns up to a site on Monday unable to work.
-
Budget variance reporter
Each month, the three or four budget lines that actually moved get explained from the transactions behind them -- so the review is a decision rather than a hunt through a spreadsheet.
-
Petty cash tracker
The tin balances itself. Every spend is a photo of a receipt, every top-up is a line, and the running balance is right at four in the afternoon rather than roughly right at month end.
-
Tax rate updater
Watches the official sources for the tax rates and thresholds your systems have hard-coded, and tells a person before the change lands rather than after the first wrong invoice.
-
Invoice dispute triager
When a customer says an invoice is wrong, the system works out which of the six things they usually mean, gathers the evidence for that one, and hands a person a decision instead of a thread.
-
Subscription audit bot
Every recurring charge on the company card gets recognised, matched to an owner and a purpose, and questioned once a year -- so the tool nobody has opened since March stops renewing quietly.
-
Utility bill watcher
Every electricity, gas, water and waste bill gets read as it arrives, compared with the same month last year and with the rate you actually agreed, and only the ones that moved get mentioned.
-
Cash drawer reconciler
At close, somebody photographs the count sheet and the till report. Two minutes later the variance is worked out, explained where it can be, and only the ones worth a conversation reach anybody.
-
Timesheet validator
Timesheets get checked the moment they are submitted rather than the night before payroll -- so the missing Thursday is a question on Friday, not a scramble on the 28th.
-
Mileage claim checker
Somebody claims 84 miles to a customer site. The system checks that the trip happened, that the distance is roughly right, and that it has not been claimed before -- then pays it or asks one specific question.
-
Purchase order approver
Somebody asks to buy something, and within a minute it is either approved against a budget that is actually current, or it is sitting in front of the one person who should decide.
-
Upsell recommender
Just after an order, the customer gets one tasteful nudge — the add-on that actually goes with what they bought — with a one-tap link to add it, and nothing more if they're not interested.
-
Warranty registration handler
A customer scans the code on their new product, and moments later the warranty is registered, the expiry is on the calendar, and a reminder is set for before it lapses — no paper card, no spreadsheet.
-
Booking deposit collector
A booking comes in and the customer gets a deposit link that holds their slot — pay and it's confirmed, ignore it and the slot quietly frees up, so no-shows stop costing the business its calendar.
-
Referral tracker
Every happy customer gets their own referral link, and when a friend they sent actually buys, both sides get credited automatically — with the self-referrals and dupes quietly filtered out.
-
Review request sender
A job wraps up, and a day later the customer gets one warm, personal note asking for a review — but only if they seem happy; anyone unhappy is quietly routed to private feedback instead.
-
Back-in-stock notifier
A sold-out item comes back and the customers who asked to be told get one text — in the order they waited, with a short window to buy before it sells out again.
-
Missed-call text-back
A missed call turns into an instant friendly text back — matched to the caller, with a booking link, and escalated if no one replies.
-
Chargeback responder
Assembles the evidence packet for a payment dispute the moment one lands — order, delivery proof, and customer comms — and files before the deadline.
-
Delivery route planner
Turns the day’s orders into an optimized driver route — fewest miles, sensible stop order, a manifest for the driver and live ETAs for customers.
-
Return and RMA handler
Runs the whole returns desk — issues an RMA, prints the label, tracks the parcel back, and proposes refund or replacement with the reason attached.
-
Stock count reconciler
Reconciles a physical stock count against the system of record, flags every variance with a likely cause, and queues the adjustments for sign-off.
-
Recurring invoice generator
Generates and sends scheduled invoices from contracts and retainers — proration, tax, and a clean hand-off to the chaser when one goes overdue.
-
Job status notifier
Keeps a service customer in the loop as their job moves stage to stage — “received → in progress → ready” — with photos and an honest ETA.
-
Product image cleaner
Turns a phone snapshot of a product into catalog-ready images — background removed, cropped per channel, watermarked, in seconds.
-
Lead enricher
Turns a raw inbound lead into a clean, deduped, enriched record before it ever reaches the CRM — and quietly drops the junk.
-
Gift card ledger
Issues, redeems, and expires gift cards and store credit — accurate balances, atomic redemptions, and fraud caps that stop abuse.
-
Dunning recovery
Recovers failed subscription payments — a smart retry schedule, branded dunning emails, and access that pauses and restores itself.
-
Order status responder
Answers “where’s my order?” the moment it’s asked — matches the customer to their order, pulls live tracking, replies with an ETA, and escalates the stuck ones.
