What I'm looking for
I am a senior front-end engineer with 8+ years building high-impact web and mobile experiences using React, React Native/Expo, TypeScript, Next.js and Tailwind. I combine hands-on engineering—component libraries, API design, and performance optimization—with leadership as a staff/dev lead to raise code quality and team delivery.
I champion AI and LLM integration to accelerate development workflows, reduce bugs, and improve user outcomes, having led migrations, CI/CD automation, and prolific cross-functional initiatives that improved engagement, uptime, and developer productivity.
