API & Backend Engineering

Frequently asked questions

Should I use REST or GraphQL for my API?

REST is simpler and works well for most products. GraphQL is worth the overhead when clients need flexible querying of complex data. We recommend the right choice for your specific use case.

Do you write API documentation?

Yes. Every API we deliver includes OpenAPI/Swagger documentation. Clients can hit a /docs endpoint and see every endpoint, parameter, and response schema.

How do you handle authentication in APIs?

We implement JWT-based auth or OAuth 2.0 depending on your requirements. For multi-tenant APIs we add row-level security at the database layer to prevent data leakage.

Can you optimize an existing slow API?

Yes. We audit your existing API, identify bottlenecks — usually N+1 queries, missing indexes, or lack of caching — and implement targeted fixes with before/after benchmarks.

Do you build microservices or monoliths?

For most early-stage products, a well-structured monolith is the right call. We build microservices when there is a genuine scaling or team separation reason, not as a default.
