What I'm looking for

I’m available for remote or freelance opportunities.

Since 2023, I’ve worked as an independent freelance developer, designing and maintaining web and mobile applications for different business and technical requirements. My work includes features for inventory, orders, deliveries, billing, reporting, and data management.

At PGS, I modified and enhanced a business application, developing inventory and delivery-tracking modules, reporting features, and an Android application. I also performed functional and integration testing on web and mobile applications.

At SBC, I developed PHP and Symfony web applications and performed manual testing across projects. In my freelance work, I use generative AI and AI-assisted development tools for code analysis, debugging, testing, documentation, and technical problem-solving.
