A clean contract between every system
API
Gateway
A clunky, undocumented API quietly kills integrations and partnerships before they start. We design production-grade APIs — REST, GraphQL, gRPC — with secure auth, rate limiting, and docs so clean that developers onboard themselves.

The API is the product's front door
Every integration, partnership, and frontend depends on it. We design APIs developers want to build against — and that hold up when real traffic arrives.
OpenAPI specs and an interactive console mean partners onboard themselves in an afternoon — instead of a quarter of back-and-forth that kills the integration.
OAuth2/JWT auth, rate limiting, request validation, and scoped keys built in — so the API survives real traffic and a security review, not just a demo.
Designed and load-tested for p95/p99 latency targets, with caching and pagination, so performance stays steady as usage climbs.
REST, GraphQL, or gRPC — chosen to fit your clients and your stack, often in combination, instead of forced into one tool.
What you get
The contract, the docs, the security, and the proof it performs — everything a developer needs to trust your API.
From schema to launch
We design the resources, contracts, and schema first — so the API is coherent and stable instead of accreting endpoints over time.
Mock endpoints let your frontend and partners build against the contract before the back end is finished, catching design issues early.
We implement the data layer, auth, validation, and rate limiting, with the contract enforced and documented as we go.
We benchmark against your latency and throughput targets, tune, and ship with monitoring and versioning in place.
An API, in production
A fintech's partners abandoned integrations because the API was slow and undocumented. We redesigned it into a clean, documented, load-tested platform partners could self-serve.

“Partners used to give up halfway through integrating us — the API was slow and the docs didn't exist. The redesign made it self-serve: latency dropped tenfold, and we went from a trickle of integrations to several a month. It opened a whole channel.”
Straight answers
API architecture design is defining how your systems and partners talk to each other — the endpoints, data contracts, authentication, versioning, and performance characteristics. A well-designed API is secure, documented, and stable, so developers can integrate against it without hand-holding.
REST is the safe default for public APIs and standard integrations; GraphQL shines when complex frontends need flexible queries; gRPC is best for fast internal microservice communication. We often combine them and recommend the right fit for your stack rather than forcing one.
We implement OAuth2 or JWT authentication, rate limiting, strict request validation to block injection, TLS enforcement, and sensible CORS policies — plus scoped API keys for partners. Security is designed in, not patched after a breach.
Yes. We ship self-documenting APIs with OpenAPI/Swagger specs and an interactive console, so frontend and third-party developers can explore and test endpoints themselves — which is what turns an afternoon integration into reality.
Absolutely. We run API modernization sprints: profiling performance, fixing inconsistent contracts, adding versioning and docs, and hardening security — often without breaking existing consumers, using versioning and deprecation paths.
Point us at your API or your integration goals. We'll design endpoints, auth, and docs clean enough that developers integrate without ever emailing you.
