About Me

The engineer who builds at scale, teaches, and publishes.

Backend Software Engineer passionate about building scalable financial systems, mentoring future engineers, and advancing technology through research and continuous learning.

At Pathao Pay, I design and build mission-critical financial systems powering Bangladesh's digital payment ecosystem. My work spans transaction profiling, merchant payouts, cashback engines, card payments, and banking integrations in collaboration with Mutual Trust Bank, City Bank, and national payment networks. I primarily work with Go, Python, PostgresSQL, AWS, and Apache Airflow to build reliable, high-throughput distributed systems.

Beyond industry, I serve as an Adjunct Faculty, teaching Software Engineering and System Analysis & Design while helping students connect theory with real-world engineering practices. Previously, I taught Java and Data Structures & Algorithms laboratories. My journey also includes military leadership training at the Bangladesh Military Academy and research contributions with over 250 scholarly citations, reflecting my commitment to continuous learning and technical excellence.
