About Me

Hi, I'm Limber Martinez, IT specialist trainee (IHK) focused on Python backend development. Microsoft AI-900 certified. I build REST APIs with FastAPI, manage data with PostgreSQL and deploy with Docker.

During a 6-month professional engagement, I worked with Odoo 18 (Python), PHP Laravel and Scrum teams. Now I develop my own products with FastAPI backend, PostgreSQL, Redis, automated testing and Docker deployment — six of them live in production.

Additionally, I use Next.js and React for frontends and leverage AI tools productively in my development workflow. Available in Dortmund and remote.
