What I'm looking for

I'm looking to build scalable, high-performance backend systems where I can apply Java, Spring Boot, microservices, database optimization, and performance tuning to deliver measurable business impact.

I've built scalable backend services for Viking Consulting's Kasparium warehouse automation platform, improving operational throughput by 30% and reducing third-party synchronization delays by 40%.

I tune Java, JPA, and database-heavy systems to improve real-world performance. My query optimization reduced heavy-module query times by 50–70%, while JVM tuning improved API latency by approximately 25%.

At Dutch-Bangla Bank, I developed Card Delivery and E-Commerce Merchant Payment systems and achieved 40% faster transaction processing through indexing, partitioning, and stored procedures. I also delivered pharmacy and canteen management systems for Chittagong Maa Sishu O General Hospital.

I'm focused on clean, modular services, secure REST APIs, microservices, reporting, and production-ready engineering across Java, Spring Boot, Oracle, MySQL, Docker, AWS, and CI/CD practices.
