API development & integration
Stop retyping data between systems that should be talking to each other.
Delivered for companies in the United States and in Saudi Arabia and the Gulf. How we work
What this includes
- REST and gRPC API design
- Third-party integrations
- Webhook architecture
- Documentation developers can use
- Authentication and rate limiting
- Monitoring and alerting
What it is
Most operational pain in a growing company is not a missing feature — it is a gap between two systems that a person is filling by hand. We build the APIs that expose your data cleanly, and the integrations that close those gaps, with the error handling that decides whether an integration is reliable or merely demonstrable.
What is included
- REST and gRPC API design
- Consistent resources, predictable errors, sane pagination and versioning that lets you change things later without breaking your consumers.
- Third-party integrations
- Payment gateways, shipping carriers, CRMs, accounting systems and marketplaces — including the ones with poorly documented, badly behaved APIs.
- Webhook architecture
- Receiving and emitting events with retries, idempotency and a replay path, so a five-minute outage on either side does not silently lose data.
- Documentation developers can use
- OpenAPI specs and worked examples. If your partners need a call with us to integrate, the API is not finished.
- Authentication and rate limiting
- OAuth, API keys and quotas configured so an integration partner cannot accidentally overwhelm your system.
- Monitoring and alerting
- Integration failures surface to you rather than to your customer. Most integrations fail quietly, which is the worst way to fail.
Reliability is the whole product
An integration that works when everything is healthy is easy. The engineering is in the rest: timeouts, retries with backoff, idempotency keys so a retry does not double-charge, dead-letter queues for what still fails, and enough logging to answer “what happened to order 4471” months later.
Working with APIs you do not control
Third-party APIs change, rate-limit and go down. We build assuming that, so your system degrades gracefully instead of stopping — and so you find out from a dashboard rather than a customer.
What happens next
From inquiry to work starting.
No obligation at any point before the scope is signed, and nothing you receive along the way is withheld if you decide not to continue.

A 30-minute call
You talk to the people who would do the work. We ask what you are trying to achieve, what exists today and what your constraints are. No sales screening call first.
- 2
A written scope and a price
We review your requirements with the engineers who would build it, work out what delivery actually takes, and send a scope with a number attached. Usually a few days, not an hour.

A small first commitment
Most engagements open with a paid discovery sprint or a defined first release — enough to prove how we work before anything larger. What the sprint produces is usable on its own, whether or not we continue.
Proof, not promises
Work our team has delivered.
Each one is written up in full, with the figures that were measured. We would rather be specific than impressive.
5sales channels in one order queue
In-house product. A grocery business selling through five channels at once, where the real cost was not selling — it was the nightly reconciliation between a register, a spreadsheet, a phone and an online store that never quite agreed.

In-house product. A recurring-delivery business where the operational load is not the deliveries themselves but the arithmetic around them — who gets what today, who paused, who owes, and what changes when one customer skips a week.

A facility-management company. Its buyers are procurement teams comparing vendors on paper, so the site has to make the single-vendor argument itself — and then make the inquiry effortless.

Common questions
What does this cost?
Dedicated teams are priced monthly by team makeup; project work is priced from a written scope. We quote after a requirements conversation with our technical lead rather than from a rate card, so the number reflects what your work actually takes. Most relationships start with a paid discovery sprint, which is small enough to say yes to and gives us both something real to price from.
How does communication work during a project?
You get a named delivery lead, a demo of working software every week rather than a written status report, and a board and repository you can open at any time. We work across US and Gulf hours, so meetings happen at a normal hour for you — and we are a US company, so when you want to shake hands before committing, we meet you in person.
Who owns the code?
Your contract sets this out before work starts. Where it assigns the code, infrastructure configuration and design files to you, we work in your accounts and repositories wherever possible, and you get a working handover if you bring the work in-house or move to another vendor.
Do you only work in certain programming languages?
No. The stacks listed on our service pages are the ones we reach for by default, not the limit of what we take on. We work in whatever language and framework the job calls for — and when you already have systems running, we work in what they are built in rather than arguing for a rewrite. If your own team will maintain the result, that settles it: we build in what your team knows.
