What I'm looking for

I seek frontend or full-stack roles where I can build scalable user experiences, mentor teams, and ship tested, maintainable code in collaborative, product-focused environments.

I am a frontend-oriented JavaScript and TypeScript engineer with over five years building high-traffic e-commerce and SaaS applications, focused on React, Vue, Next.js, and cloud-native architectures.

I have delivered measurable business impact — from an express checkout that improved conversion to a policy management UI that eliminated YAML editing errors — while maintaining strong test coverage with Jest and Playwright.

I mentor teammates, conduct thorough code reviews, and collaborate cross-functionally with design, backend, and product teams to ship maintainable solutions across microfrontend and BFF architectures.

My experience spans modern frontend stacks, GraphQL and Node.js backends, and cloud/tooling ecosystems (AWS, Azure, Docker, CI/CD). I pursue pragmatic engineering that balances developer velocity, reliability, and user outcomes.
