Roldan Salazar Ruiz

I am a freelance full-stack developer, focused on reliability and "production-first" work. I help SMEs and startups build and evolve stable, fast, and easy-to-maintain web applications: backend (APIs, integrations, databases) and frontend (clear UX and good performance).

In addition to programming, I ensure the product is deployed and runs well on a daily basis: cloud deployments, delivery automation (CI/CD), reproducible environments, monitoring, and alerts. The goal is to release changes with confidence, reduce incidents, and have visibility when something fails.

I also have experience in Linux/UNIX systems and networks, which allows me to address performance issues, apply basic security and continuity measures (backups, permissions, hardening), and improve operations.

How I usually work: I review the current state and business priorities, propose a phased plan (quick wins + structural improvements), and deliver progress iteratively, with frequent communication and useful documentation.

If you need a technical partner for new features, modernizing an existing system, or professionalizing cloud deployment, let's talk.
