What We Do

End-to-End API & Backend Systems

One partner covering strategy, build, cloud, security, quality, and support.

High-Performance REST & GraphQL APIs

Cleanly versioned, documented (OpenAPI/Swagger), and hyper-fast APIs engineered for web, mobile, and third-party consumers.

  • OpenAPI 3.0 specs & automated docs
  • GraphQL schema stitching & federation
  • Sub-50ms endpoint latencies

Microservices & Serverless Backends

Event-driven microservices architectures on AWS Lambda, Google Cloud Run, or Kubernetes that autoscale instantaneously.

  • Zero cold-start optimizations
  • Asynchronous event sourcing
  • Independent service deployability

Enterprise API Security & Auth

Hardened authentication pipelines with OAuth 2.0, mTLS, rate limiting, DDoS protection, and secure API gateways.

  • Kong & AWS API Gateway management
  • JWT token signing & revocation
  • Token bucket rate limiting & throttling

Asynchronous Message Queues

Decouple heavy workloads and prevent bottlenecks with distributed queues: Kafka, RabbitMQ, Redis, and AWS SQS.

  • Pub/Sub messaging patterns
  • Idempotent worker processing
  • Dead-letter retry queue mechanisms

Database Design & Optimization

Relational and NoSQL schemas optimized with indexing, caching, connection pooling, and read replicas.

  • PostgreSQL & MySQL optimization
  • Redis distributed caching
  • Connection pooling with Prisma/PgBouncer

Automated Testing & SDK Generation

Comprehensive end-to-end API test suites and auto-generated client SDKs for TypeScript, Python, and Go.

  • Automated Postman/Newman test runs
  • Contract testing with Pact
  • Auto-generated typed client SDKs

Frequently Asked Questions

Key considerations regarding our technical execution and delivery models.

Do you design APIs using REST or GraphQL?

We support both. We recommend REST for public third-party developer platforms and GraphQL when frontend clients require flexible, consolidated data fetching.

How do you ensure API documentation stays up to date?

We practice code-first or spec-first documentation using OpenAPI / Swagger tools that automatically validate and update docs on every deployment.
