Arif Hossain is a senior full-stack engineer from Dhaka with 7 years of experience building production-grade web and mobile products using JavaScript/TypeScript, React/Next, React Native, Node.js, NestJS and modern databases like MongoDB and MySQL. He has led web teams and shipped end-to-end systems across fintech and Web3 payments — including eSIM B2B frontends, decentralized banking UIs, batch payout dashboards, and merchant on/off‑ramp platforms. Comfortable across frontend, backend and cloud (Prisma, AWS, Docker, Route53, S3), he pairs hands-on implementation with team mentoring and code reviews. Notably, he transitioned from freelance beginnings to leading web efforts at startups acquired for their products, and has experience integrating GPT models and Web3Auth into customer-facing flows. Reachable for collaboration on MERN and React Native projects, he blends pragmatic engineering with product-level ownership.
