What I'm looking for

I'm looking to build impactful full-stack, mobile, or AI-powered products where I can own features end to end, learn from strong engineers, and solve practical user problems.

At ThinkAct AI, I built multi-tenant RBAC, onboarding flows, and real-time multilingual conversations for a mortgage workflow automation platform, reducing signup time by 40%.

I've also built Android fintech workflows at Vighnotech and shipped products spanning React Native, Flutter, Next.js, NestJS, AI-assisted grading, and decentralized crypto investing.

My open-source React Native styling library, NativeFlow, crossed 50k+ NPM downloads, and I enjoy solving algorithmic problems and creating competitive-programming challenges.
