What I'm looking for

I'm looking to build maintainable backend systems with clear APIs, reliable data models, strong documentation, and room for software to evolve after deployment.

At Jonsero, I design, build, and maintain the backend for I'mHere, a web platform developed for Factory. I create backend architecture, REST APIs, business logic, data models, validation, and API contracts for frontend integration.

Since 2021, I've delivered freelance software development and technical support across backend, desktop, and systems projects. My work spans Node.js, TypeScript, PostgreSQL, Prisma, Docker, C, C++, Java, Python, and Linux, grounded in the project-based Common Core at 42 Luanda.
