Full stack developer working mainly in React.js, Next.js, and Node.js. I’ve shipped customer-facing features, built REST APIs, integrated AI tools (Google Gemini and OpenAI), and implemented payments (Stripe) across production apps. I enjoy taking a feature end-to-end—from database to UI—while collaborating with teams across time zones. I work with multi-tenant backends and modern tooling including PostgreSQL/MongoDB, Prisma, Docker, Jest, and AWS/Vercel deployments.…Full stack developer working mainly in React.js, Next.js, and Node.js.
