About this gig

Hi, I'm Paulo, a Senior Full Stack Engineer and Tech Lead with 8+ years building backends that hold up in production. I built payment infrastructure at Stone handling 10,000+ requests per second and my own fintech (Batameta) on an event-driven NestJS stack.


I'll design and build a backend that is clean, tested and ready to scale: Node.js/NestJS, TypeScript, PostgreSQL/Prisma, REST APIs, JWT/OAuth2 and Docker, plus RabbitMQ and Redis when you need them. I follow Clean Architecture, DDD and TDD, so the code stays easy to maintain and extend.


What you get: a solid API, a real database schema, authentication, automated tests and a Dockerized setup ready to deploy. I can also integrate third-party services like Stripe, PIX, Twilio and OpenAI.


Message me with your idea before ordering so I can scope it right and recommend the best package.
