What I'm looking for

I’m seeking a collaborative, growth-oriented role building high-impact web products where I can lead front-end architecture, mentor teammates, and drive performance and accessibility.

I am a Full Stack Engineer with 6+ years of experience focused on front-end development using React, TypeScript, and modern design systems, delivering fast, accessible web applications in cross-functional teams.

I led frontend efforts on major projects, implemented scalable patterns (MVC, MVVM, Atomic Design), and improved performance through lazy loading, code splitting, and test automation with Jest and Cypress.

I prioritize clean architecture, modular component design, accessibility, mentorship, and collaboration, and I’m seeking to contribute to high-impact digital products at scale.
