Custom software development
Backend systems, web applications and APIs built around your process.

System and API integrations
Dependable connections between the applications you already run, the services you buy and the platforms you sell on.
Most companies don’t need another system. They need the systems they already have to talk to each other.
Orders live in one place, stock in another, invoices in a third, and someone copies numbers between them by hand every morning.
That copying is where the errors come from. It is also, more often than not, among the cheapest things in the company to automate, because the work is already specified: somebody is performing it by hand, correctly, every morning, and can tell you exactly what the rules are.
An integration connects those systems over their APIs, keeps the data in step and tells you when something goes wrong. The interesting part isn’t the happy path. It’s what happens when a platform goes briefly unreachable or sends the same event twice, and what you do about a field that changed overnight without anyone mentioning it.
That’s where most of the work goes: retries, idempotency and logging you can read afterwards. An integration that only works when everything else is working is not much of an integration.
01 / How it runs
From a manual step to something that runs by itself.
The first question is always whether the connection is worth building. Some manual steps are cheaper to leave alone, and you should hear that before you pay for anything.
-
01
Map what moves, then check what the APIs allow
Which data goes where, how often, who owns it, and what has to happen when two systems disagree. Then the rate limits, the authentication, the fields that turn out not to exist. Most surprises turn up here, and finding them early is the point.
-
02
Build for the bad days
Retries with backoff, protection against duplicate events, and logging that tells you what happened rather than that something happened.
-
03
Watch it in production
Alerting on failures that matter, so a broken connection is something you’re told about instead of something a customer reports.
02 / What you get
Everything that comes with a connection.
-
A running connection
Scheduled or event-driven, whichever the systems actually support, deployed where it can reach both sides.
-
Handling for failure, not just success
Retries, duplicate protection and a clear rule for what happens when a record can’t be matched.
-
Logs you can read
Enough detail to answer "what happened to this order" without opening the source code.
-
A written field mapping
Which field on one side becomes which field on the other, and what the exceptions are. This document outlives the memory of everyone involved.
03 / When to look elsewhere
Some connections are not worth it.
If a step runs twice a month and takes five minutes, automating it will cost more than it saves for a very long time. Count the real hours before deciding.
If one side has no API and no export, an integration means scraping a screen, and that breaks the first time a supplier changes their layout. Sometimes that’s still the right call, but you’re buying maintenance rather than a one-off build.
If both systems are due to be replaced next year, connecting them now is work you throw away. Sometimes waiting is the better engineering decision.

Have a project in mind?
A short conversation is usually enough to tell whether it’s a good fit. If it isn’t, you’ll hear that too.
