Top SchoolA Rejuan is a results-driven software engineering leader with 12 years of experience building high-throughput, Java-based distributed systems and real-time media platforms. He has led architecture and delivery for mission-critical projects—from an API gateway handling around a billion daily requests to a cloud-based call center billing system managing 1,000+ concurrent calls and a video streaming stack serving 48k+ concurrent viewers at 25 Gbps. Skilled in microservices, performance optimization, and TDD, he combines hands-on engineering with team leadership and developer unblocking. Based in Dhaka, he also brings practical integration experience (Zapier, CRMs, BrightSign) that bridges product needs and operational monitoring. An engineer who moves between protocol-level work (custom UDP/RUDP servers and Netty-based load balancers) and high-level API design, he thrives on making large-scale systems observable, resilient, and easy to integrate.
