What I'm looking for

I seek roles where I can lead engineering efforts, build TypeScript front ends and AI features, own cloud architecture, and mentor teams in a results-driven, collaborative environment.

I am a front-end and full-stack engineer who ships fast TypeScript UIs and integrates AI features to drive measurable product outcomes.

I build React and Next.js products, design APIs, and deliver Python-based backend services using Django, Flask, and FastAPI for scalable systems.

I have led remote engineering teams, driven architecture and DevOps across AWS, GCP, and Azure, and improved metrics such as conversion, bundle size, and TTI through focused engineering work.

I prioritize testing, performance, accessibility, and clear metrics, and I mentor engineers while owning UX, API design, delivery, and cloud deployments.
