Backend Development & APIs
Robust, scalable RESTful architectures.
I design and build backends with NestJS, Node.js, Laravel, Django and FastAPI: RESTful and GraphQL APIs, secure authentication, distributed task queues (Celery, SQS) and asynchronous processing of datasets exceeding one million records with Redis.
Data modeling in PostgreSQL, MySQL, MongoDB and Firestore, focused on query performance and decoupled microservice architectures.
What you get
- Documented RESTful and GraphQL APIs
- Microservices with queues and cron jobs
- Authentication and authorization (JWT, OAuth)
- Real-time features and chat (Socket.io)
- Query optimization and Redis caching
