Summary
👤
Senior🎓
Top SchoolMahmudul Hassan is a seasoned backend engineer with 11 years of experience building API-first, microservice-based systems and real-time platforms from Dhaka. He specializes in Golang for microservices and CLIs (5+ years) while also bringing deep Node.js and frontend experience (8+ years) with React/Redux, enabling full-stack problem solving. Mahmudul has repeatedly diagnosed and fixed elusive production issues—memory leaks and resource exhaustion—using tools like pprof and targeted refactors to restore stability at scale. At Pigeonhole Live he moved systems toward event-driven architectures (RabbitMQ), hardened public APIs with rate-limiting, and applied Amazon Bedrock for automated attendee summarization—demonstrating a blend of systems engineering and applied AI. He also has a track record of modernizing legacy stacks (websocket → Socket.io, vanilla JS → React) and mentoring teammates during integration and onboarding. His early training in chip design and automation gives him a pragmatic, tooling-first approach to complex engineering problems.
