Sobre mim
From idea to working API. Hi! I'm Jeferson, a backend developer from Costa Rica. I build secure, documented REST APIs and web apps with Node.js, TypeScript, Express and PostgreSQL, and I also work with Go and React. I deploy with Docker, Linux and GitHub Actions, and I have built AI chatbots that answer questions from documents (RAG). I'm new on Fiverr, so I put extra care into every order and keep you updated at every step. Tell me about your project and I'll reply with a clear plan, timeline and price.... Saiba mais
