Backend & API Development
APIs that handle 50M events a day and still have room to grow
We design and build backend systems — REST APIs, GraphQL, microservices, real-time infrastructure, and data pipelines — that are fast, secure, and architected to scale. No hacks, no shortcuts, no rewrites in 12 months.
What's Included
- REST and GraphQL APIs — documented, versioned, and tested
- Real-time systems with WebSockets and Server-Sent Events
- High-throughput data pipelines processing millions of events
- AI-ready infrastructure — vector stores, embeddings, streaming
- Database design and query optimisation (PostgreSQL, MongoDB)
- Security-first — OWASP, rate limiting, JWT/OAuth2, encryption
APIs Built to Last
We don't just make APIs that work on demo day. Every endpoint we ship is documented with OpenAPI, versioned for backwards compatibility, covered by tests, and structured so your own engineers can maintain it confidently.
Architected for Your Traffic, Not Ours
Whether you're at 1,000 requests a day or 100 million, we design systems that grow with your load without requiring a rewrite. We've built analytics APIs processing 50M events per day and payment backends handling thousands of concurrent transactions.
Security Is Not an Afterthought
Every API we build follows OWASP best practices: input validation, rate limiting, proper auth/authz, encrypted secrets, and HTTPS everywhere — audited before launch, not patched after a breach.
Frequently Asked Questions
Do you build REST or GraphQL APIs?
Both. We choose REST when you need simple, cacheable, widely-compatible endpoints, and GraphQL when clients need flexible, typed queries over related data. Every API we ship is documented, versioned, and covered by automated tests.
Can your backends handle high traffic and scale?
Yes. We architect for scale from day one using horizontal scaling, caching with Redis, message queues like Kafka, and database query optimisation. We have built pipelines that process tens of millions of events per day with room to grow.
How do you secure the APIs you build?
We follow OWASP best practices — JWT or OAuth2 authentication, role-based access control, rate limiting, input validation, and encryption in transit and at rest. Security is built into the design, not bolted on afterward.
Can you make our backend AI-ready?
Yes. We add vector stores, embeddings, and streaming infrastructure so your existing backend can power RAG pipelines and AI features without a rebuild.
