APIs Built for the Long Run
REST, GraphQL, webhooks, integrations — versioned, documented, monitored.
DIRECT LINE — +92 314 7046916
APIs are easy to build and hard to maintain. The first version ships fast; year two is when authentication is a mess, versioning is impossible, the docs are out of date, and every integration is one bad deploy away from breaking. Real API design pays the maintenance tax up front.
We design APIs contract-first: OpenAPI for REST or schema-first for GraphQL. Versioning, auth, rate limiting, and observability are wired in before the first endpoint goes live. Documentation is generated from the contract, so it stays correct.
- 01REST (OpenAPI) or GraphQL schema-first design
- 02Authentication (OAuth2, JWT, API keys) + RBAC
- 03Rate limiting, retries, idempotency keys
- 04Webhook delivery system with retries + signatures
- 05Auto-generated docs (Stoplight, Redoc, GraphiQL)
- 06Third-party integrations (Stripe, HubSpot, Salesforce, etc.)
- 07Monitoring + alerts (latency, error rate, contract drift)
- Node.js / Python / Go
- OpenAPI 3.1 + Orval
- GraphQL (Apollo, Hasura)
- PostgreSQL + Redis
- Kong / API Gateway
- Datadog, OpenTelemetry
REAL PROJECTS, ANONYMIZED ON REQUEST.
Most of our work is under NDA. Reach out for a walkthrough of relevant projects in api development & integration — we will share scope, architecture, and outcomes for engagements that match yours.
[ REQUEST A WALKTHROUGH ]QUESTIONS WE GET A LOT.
REST or GraphQL?
REST for public-facing or simple CRUD APIs. GraphQL when clients need flexibility (mobile apps with varied views, admin tools that aggregate from many sources). We pick per project. Most product APIs are fine as REST + OpenAPI.
How do you handle versioning?
URL versioning (/v1, /v2) for major breaking changes; non-breaking additions ship to the current version. Deprecation policy is documented up front. We do not silently change response shapes.
Can you integrate with our existing systems?
Yes. Common integrations: Stripe, Salesforce, HubSpot, NetSuite, Slack, vendor APIs with bad docs. We document every integration so the next engineer does not have to reverse-engineer it.
Do you build internal APIs only, or public APIs too?
Both. Public APIs need extra: developer portal, sandboxes, SLA monitoring, and a versioning policy you can stand by for years.
