Freelancer profile translated to English.

Description

Backend developer with a focus on Node.js, Python, and databases (PostgreSQL, Oracle). I help companies build and maintain robust REST APIs, optimize queries and solve performance bottlenecks, and integrate backend with frontends in Next.js.

I have 3 years of professional experience and personal projects from start to finish: a price comparator (juegosbaratospc.com) and a desktop application with scraping and image processing (Electron + Puppeteer + Sharp).

I adapt quickly to existing codebases, write maintainable code, and communicate clearly and directly throughout the project.
