About Me

I specialize in designing and engineering high-throughput backend APIs, microservice message architectures, and sleek frontend layouts. From architecting core banking modules with e-KYC and Nagad integrations to developing automated HR databases with millions of rows, I thrive on solving complex technical challenges with clean, robust code.

My approach centers around the Software Development Life Cycle (SDLC), implementing solid Object-Oriented Design (OOD) patterns, and using advanced caching, asynchronous pipelines, and profiling to extract maximum performance.
