A breaking change doesn't just break your app — it breaks every client, partner and integration depending on your contract. For 10+ years we've placed engineers with 70+ businesses, including API developers who design for versioning and evolution from day one, not after the first breakage.
These are the problems teams hit designing and maintaining APIs.
Every API change breaks at least one downstream client.
There's no versioning strategy, so old and new clients fight for the same endpoint.
Documentation is outdated or missing, so partners keep asking basic questions.
Rate limiting and auth were bolted on later instead of designed in.
Error responses are inconsistent, so clients can't handle failures reliably.
You're not sure whether REST or GraphQL is the right fit for your use case.
An API is a contract with everyone who consumes it. We place developers who design that contract to evolve gracefully, not break it every release.
If other teams or partners depend on your API, this is for you.
Partners build on your API and need a stable, well-documented contract.
Multiple frontends or services depend on the same backend contract.
Every deploy causes a scramble, and you want that pattern to stop.
Each problem above maps to how we build. Here's how we fix it.
Changes ship without breaking existing clients on the current version.
Old versions retire on a clear, communicated timeline, not abruptly.
Clear, current docs written alongside the API, not as an afterthought.
Auth and rate limiting designed as part of the API, not added under pressure.
Uniform error responses so clients can handle failures predictably.
We recommend REST or GraphQL based on your actual client needs, not a default.
We maintain APIs with real external consumers ourselves, so we design for the change that's coming, not just the feature shipping today. For 10+ years and 70+ clients, that discipline is what we place engineers to deliver.

We scope your API's clients and requirements — no cost, no obligation.
We match vetted API developers ready to interview.
They build the contract with versioning and docs from the start.
Your API goes live, and future changes ship without breaking clients.
It depends on your clients' needs — REST for simplicity and caching, GraphQL when clients need flexible queries over complex data. We'll give you an honest recommendation, not a default.
Usually a versioning gap — changes are shipped without a strategy for existing clients. We design APIs with versioning and deprecation paths from the start.
Yes, documentation is part of the deliverable — an API without clear docs is much harder for other teams or partners to actually use.
We match from an existing vetted pool, so you're typically interviewing within days and can have someone contributing to your codebase shortly after.
Both. Many clients start on contract to prove fit on real work, then convert strong performers to permanent.
