What I'm looking for

I seek a role building scalable, user-centric frontend systems with strong collaboration, mentorship opportunities, and emphasis on performance, testing, and growth.

I am an experienced Front-End Developer with over five years building scalable, responsive applications using React and TypeScript. I focus on performance, accessibility, and maintainable component-driven architectures that serve enterprise needs.

At Siloam Hospital Group I led a replatforming project and built a custom DMS frontend that handled 10,000+ monthly documents and improved finance processing times dramatically. I also designed a multi-threaded PDF rendering system and created a shared React UI component library adopted by 15+ teams.

I have improved product metrics across multiple companies — increasing conversion rates, reducing page load times, and cutting defect rates through testing and BDD practices. I mentor teams on modern frontend patterns, testing with Jest and Playwright, and efficient state management with Redux and Zustand.

I seek to deliver high-quality, user-focused interfaces while collaborating closely with backend and product teams. I bring a pragmatic, results-oriented approach to building reliable, maintainable web applications.
