What I'm looking for

I'm seeking backend or fintech engineering roles where I can design scalable Java microservices, ensure payment compliance, mentor teammates, and grow in DevOps and ML within a collaborative Agile company.

I am a software engineer focused on building robust Java-based microservices and payment systems, and I led development of a Bangladesh Bank-certified payment wallet at Shamadhan Services Limited while contributing to ShopUp and Prime Bank wallet projects. I apply clean code, comprehensive testing, and performance monitoring to deliver maintainable, high-quality solutions.

I work with Spring Boot, gRPC, Kafka, PostgreSQL, Docker, Kubernetes, AWS, Prometheus/Grafana and distributed tracing tools, and I mentor junior developers while participating actively in Agile teams. I hold a BSc (CGPA: 3.61, Second Position) with research experience in CNN-based crop disease recognition, multiple publications, and a strong interest in combining backend engineering, fintech, and machine learning.
