About Me

Bachelor of Science in Information Technology graduate from Cagayan State University.

I build full-stack web applications, mostly with React, Next.js, and TypeScript on the front end and Supabase or Node.js behind it. Recent work includes an online store for a local retailer, a membership platform for a community organization, and an internship tracking system for my university.

I care about writing code that is readable and maintainable, and about shipping interfaces that work properly on a phone as well as a desktop.

I am currently looking for a junior developer or IT role where I can keep learning from a more experienced team.
