What I'm looking for

I seek frontend-focused roles that prioritize UI performance, DX, SSR/ISR and cross-functional collaboration, with opportunities to lead and mentor.

I am a Senior Full-Stack Engineer with a frontend-first approach and over eight years building performant, accessible web applications. I specialize in React and Next.js, state management, testing, and CI/CD, and I enjoy improving UI performance, developer experience, and SSR/ISR workflows.

I have led squads, mentored engineers, and partnered closely with Product and Design to deliver production-ready features—ranging from wallet platforms and e-commerce to CMS and release dashboards—while establishing design systems and migration strategies for micro-frontends.

I bring backend experience with Node/Express and Firebase, strong testing and tooling practices (Jest, RTL, Cypress, GitHub Actions), and a track record of improving DX, SEO, and deployment reliability. I am currently pursuing a Master’s in Software Engineering.
