What I'm looking for

I’m looking for contract or full-time remote work where I can own React/Next.js UI end-to-end, improve performance and SEO, and ship with strong automated testing and reliable CI/CD.

I build React and Next.js products that ship—backed by 8+ years refactoring and owning production UI across SaaS, B2B, and B2C. My open-source work runs in production at Amazon, and I bring end-to-end responsibility across design handoff, build, and release.

I focus on testable UI and measurable outcomes: GraphQL/Node.js experience, automated testing with Cypress/Playwright/Jest, and performance/SEO improvements using metadata, structured data, and Core Web Vitals telemetry. I also enjoy raising team quality through mentoring, code reviews, and stable CI/CD while modernizing legacy modules.
