What I'm looking for

I’m seeking opportunities to contribute in a challenging and dynamic environment that fosters growth and innovation, where I can build scalable, secure backend systems, strengthen system design, and keep learning new technologies.

I’m an experienced backend software engineer with 4+ years in backend development, specializing in Java, Spring Boot, and microservices architecture. I currently work in the banking domain, implementing and enhancing core banking functionalities while building scalable, secure, and efficient financial systems.

At CITY BANK PLC, I develop and maintain middleware by integrating third-party APIs, and I’ve implemented Spring Security to secure API consumption. I engineer backend solutions for MFS platforms (OK Wallet, Meghna Pay, Pocket Wallet, Nagad, and Rocket), optimize legacy APIs for performance, and support business onboarding for vendors, MFS, and banks—collaborating closely with QA, vendor teams, and the Core Banking team to resolve issues and deliver reliable integrations.
