Rockstar🎓
Top SchoolSharfin Sakib is a Lead Senior Software Engineer with a decade of hands-on experience building full-stack systems, currently driving engineering at CORSphere after leading teams at CHEQ where he helped scale order processing from hundreds to 50k+ daily. He specializes in React/Next.js front-ends and Node backends, with strong Python and Flutter experience that let him ship everything from POS apps and cloud printing services to no-code automation tools. As one of CHEQ’s first internal engineers, he combines product-first thinking with deep curiosity about algorithms and system internals to deliver reliable, high-throughput services. His side projects include CFViz, a popular Codeforces visualizer used by CS students with ~1k GitHub stars, and a Netis router management app with 700k+ Play Store downloads—evidence of a pragmatic builder who cares about real user impact. He contributes across the stack with tooling knowledge from Docker and AWS to Puppeteer and GraphQL, and he writes about technology occasionally while training for a half marathon in the outskirts of Dhaka.
