What I'm looking for

I'm looking for backend engineering opportunities with international, multicultural teams where I can build reliable, scalable Java and Spring Boot platforms, contribute to distributed systems, and support business-critical products. I'm open to relocation to Japan and remote global roles.

I've delivered backend platforms for Grameenphone, Touch 'n Go, Rakuten Ichiba, Neogrid, and BRAC using Java, Spring Boot, microservices, and event-driven architecture. At Grameenphone, I built a high-volume Commission Management System and an Apache NiFi and RabbitMQ ingestion pipeline that transformed SFTP CSV files into structured JSON events.

I've developed payment and e-commerce services, ERP modules, reporting workflows, REST and GraphQL APIs, and optimized data layers across MySQL, PostgreSQL, and Oracle. I focus on reliable, maintainable production systems, working closely with distributed international teams through design, testing, deployment, and production support.
