- Modular API Architecture: Built on Express, Fastify, or NestJS using clean architecture.
- Auth & Security: JWT tokens with refresh tokens, Role-Based Access Control (RBAC), and rate limiting.
- Database Design: Optimized schemas in PostgreSQL, MySQL, or MongoDB using Prisma or Drizzle ORM.
- Real-Time & Caching: High-speed caching via Redis and real-time WebSockets via Socket.io.
- Documentation & DevOps: Interactive Swagger/OpenAPI docs and Docker containerization.
Whether you need an MVP from scratch or are scaling an existing API, I deliver clean code ready for production.

FAQ
Which framework do you recommend?
For enterprise and modular microservices, NestJS with TypeScript is ideal. For lightweight, high-performance APIs, Express or Fastify is fantastic. I adapt to your project needs.
Do you include API documentation?
Yes! Standard and Premium packages come with interactive Swagger/OpenAPI documentation so your frontend/mobile team can test endpoints effortlessly.
Can you optimize slow existing databases?
Absolutely. I specialize in database indexing, query profiling, and connection pooling to drastically reduce database latency and server load.
