What I'm looking for

I seek hands‑on roles building consumer web or extension products where I can own features end‑to‑end, deploy to production, and deliver measurable user value.

I am a full‑stack developer focused on building web applications and Chrome extensions using modern JavaScript/TypeScript stacks, Flutter/Dart, and Spring Boot. I design and ship end‑to‑end products—handling front‑end, back‑end, deployment, and billing integration.

My projects include a subscription chart‑animation service that converts .xlsx/.csv into downloadable animated charts, multiple Chrome extensions that enhance user workflows, and mobile apps built with Flutter and Android. I’ve worked solo and in small teams, contributing to architecture, database design, and production deployment on AWS and Firebase.

I bring a practical, product‑oriented approach: I iterate quickly, integrate analytics and billing where relevant, and focus on UX polish using Tailwind, Shadcn, Zustand, and charting libraries. I’m motivated to join teams that value shipping polished features, measurable user impact, and continuous improvement.
