Hi, I'm MD. Shahadot Hossain, a Senior Software Engineer with 5+ years of experience designing, developing, and scaling web and cross-platform mobile applications for enterprise clients, including Unilever, BAT, Nestlé, L'Oréal, and Nagad.
I build high-performance products with React.js, Next.js, React Native, Expo, and TypeScript — delivering secure, scalable solutions that serve 10,000+ users and process 100,000+ daily transactions.
What I focus on:
- Enterprise web applications & scalable frontend architecture
- Cross-platform mobile development (React Native / Expo)
- Offline-first applications with real-time synchronization
- Face detection & liveness verification
- Location tracking & geofencing
- Performance optimization & automation-driven business solutions
I also have working knowledge of backend technologies — Node.js, Express, NestJS, GraphQL, MongoDB, and PostgreSQL — and I'm continuously deepening that side to collaborate more effectively on full-stack systems and API design.
