Top SchoolSaifullah Sayem is a Senior Software Engineer based in Dhaka with a decade of professional experience building full-stack web and mobile applications, and over six years focused on modern JavaScript ecosystems like React, React Native, Next.js, and Node.js. He has led engineering efforts at product-first startups and scale-ups, designing scalable microservices, GraphQL APIs, and high-performance frontends that achieved real user traction (including a social app approaching 20k users). Comfortable across backend (NestJS, Django, MongoDB), frontend performance optimization (LCP/INP), and cloud services (AWS S3 and related tooling), he also architects dashboards, scraping pipelines, and automated reward systems. A hands-on mentor and code-reviewer, he has repeatedly built admin panels and mobile apps from scratch while coaching junior developers and enforcing testing and CI practices. Notably, he blends pragmatic product sensibility—shipping features that measurably improve engagement—with deep implementation skill across both legacy stacks and cutting-edge JS tooling.
