Hi, I'm Andres Parra. 👋

Software engineer, developer, and lifelong learner.

I write code, build things, and figure out how software should work — currently based in CúcutaCity in Norte de Santander, Colombia, Colombia, finishing my Systems Engineering degree at UFPS.

I'm the founder of RPCIDECompetitive programming platform with 400+ active users., a competitive programming platform with 400+ active users, along with a few other software projects.

I'm always experimenting with new technologies, keeping my curiosity alive, and looking for the next thing to learn.

I write about what I learn and teach — you can find my tutorials and articles on web development, programming, and AI.

I write about ai, machine-learning, linux, html, github, python, docker, git, opencode, css.

What I write about

Most of my posts cover practical, real-world topics: React and TypeScript patterns I use in production, Python for backend systems and AI experiments, and lessons learned building tools like RPCIDE and Scriio. I also dive into machine learning fundamentals, Java when the project calls for it, and whatever new stack I'm currently obsessing over.
