What I'm looking for

I’m looking for a remote Portuguese (native/bilingual) English (professional working) opportunity where I can contribute my PHP, MySQL, and JavaScript skills to back-end development and system maintenance, with room to deliver reliable improvements.

I’m an experienced Web Developer with over ten years of hands-on development, grounded in PHP Engineering and a strong command of PHP, MySQL, and JavaScript. I’ve worked from a foundational Software Engineer role at the World Food Programme to building personal and proof-of-concept applications.

I focus on back-end development and system maintenance, helping ensure websites and web applications run smoothly. I’ve also designed and deployed a critical database system using MS Access to manage humanitarian regional air transport services, similar to an airline reservation system.

Alongside development, I’ve supported and maintained computer infrastructure as a Network Assistant and as an assistant to IT managers. I bring bilingual communication (Portuguese/English) and a teaching background, and I’m seeking a remote opportunity where I can contribute reliably to development and operational upkeep.
