What I'm looking for

I want to keep building efficient, high-performance React solutions—shipping responsive, user-friendly, SEO-friendly web features with strong code quality and smooth collaboration in Agile teams (Backlog).

I’m a Frontend Developer with 4+ years of experience building and maintaining responsive, user-friendly web applications. I focus on improving existing systems and developing features from scratch, with strong experience in HTML, CSS, and JavaScript alongside modern UI development practices.

At Transcosmos Asia Philippines, I led maintenance and enhancement of the Duskin Health Rent web application, ensuring strong performance, stability, SEO optimization, and a smooth user experience. I built new pages and reusable UI components from scratch based on UI/UX designs, then improved existing features by fixing bugs, resolving performance issues, and enhancing usability. I collaborate closely with UI/UX designers and support Agile workflows using Backlog (Nulab), while continuing to advance my expertise in React.js to deliver efficient, high-performance web solutions.
