Available to hire
I’m Carlos Javier Parra Aparicio, a seasoned software developer with over 20 years of experience in backend and full-stack development. I specialize in PHP and JavaScript, with deep expertise in database architecture (MySQL, PostgreSQL, SQL Server) and a proven track record delivering mission-critical systems. I adapt quickly to new technologies, value collaboration with remote teams, and continuously strive to improve performance and maintainability.
I thrive in challenging remote environments, enjoy migrating legacy systems to modern stacks, and am motivated by solving complex problems for clients. I’m seeking a remote developer role where I can apply my experience to mission-critical systems and mentor others along the way.
