What I'm looking for

I seek an engineering role where I can own end-to-end features, work with TypeScript/React and AWS, improve system reliability, mentor teammates, and contribute to roadmap and infra automation.

I am a Full-Stack Software Engineer with 6+ years building secure, high-reliability web applications focused on TypeScript and React.

I deliver customer-facing workflows end-to-end, translating vague requirements into shipped features while designing clean, extensible systems and operating production services on AWS.

My strengths include component-driven frontend architecture with Tailwind, API-first backend development with PostgreSQL, and reliable systems patterns like retries, idempotency, and monitoring.

I bring strong ownership across design docs, code reviews, prioritization, and CI/CD-driven deployments, and I enjoy mentoring others and improving team delivery and quality.
