What I'm looking for

I seek challenging full‑stack roles at companies that value engineering quality, accessibility, observability, and mentorship, with opportunities to own architecture and scale products.

I am a Senior Software Engineer with 8+ years delivering high-impact full-stack web applications across startups and global enterprises. I focus on building performant, accessible, and internationalized React applications while integrating resilient backend services.

I've led frontend redesigns and refactors using React, Next.js, TypeScript, and TailwindCSS that improved task completion, reduced bounce rates, and scaled internationalization to 12+ languages while ensuring WCAG compliance.

On the backend and infra side, I architect and integrate Node.js, GraphQL, REST APIs, AWS (Lambda, ECS), Terraform, and CI/CD to enable resilient, observable systems and serverless workflows. I hold an AWS Certified Solutions Architect certification and have driven observability and testing improvements that reduced time-to-resolution for critical bugs.

I mentor junior engineers, author internal RFCs, contribute to design systems and developer experience tooling, and continuously optimize performance, testing, and deployment pipelines to deliver reliable production services.
