At Arya, I migrated the API layer from a Next.js-based backend to a standalone GraphQL backend, cutting production incidents by an estimated 60% and simplifying debugging and logging.

I also diagnosed a Meta Ads shadow-ban behind a 40% revenue drop, traced it to domain reputation, and drove the domain migration that restored revenue to pre-incident levels and beyond. I built a reusable video player adopted across three mobile screens and checkout flows integrating Stripe and Mixpanel.

At Stamp (via Trio), I built and maintained a marketing-operations platform using FastAPI and Next.js. I also cut monorepo build times from about 20 minutes to 10 minutes and built an AI-powered, MCP-integrated chatbot for generating marketing plans.

At Bentley Systems, I rebuilt a legacy form designer as a React application adopted across 14 teams, and migrated a shared library from Webpack to Vite, cutting its bundle size by more than 50%. Earlier, at Beeteller, I led a checkout migration from Angular 3 to Next.js, and at Incode I joined full-time to build an e-commerce platform.
