I build reliable backend systems with Java, Spring Boot, messaging, and containerized infrastructure.

What I'm looking for

I'm looking to build reliable backend systems with Java, Spring Boot, databases, messaging, and Docker while learning from experienced engineers and contributing to meaningful products.

I'm contributing backend fixes and improvements to OpenELIS-Global, an open-source laboratory information system used by medical labs in low-resource healthcare settings, using Java and Spring Boot.

Previously, I built backend CRM features at Arudra Software Services under senior developer mentorship using Node.js and MySQL. I've also built Code Judge, a real-time online coding platform that runs submissions in isolated Docker containers, queues jobs through RabbitMQ, and streams execution status over WebSockets.

I enjoy designing scalable backend services, including an OTP microservice with independently deployable API, storage, and notification components, plus custom expiring in-memory caching. My work is grounded in Java, Spring Boot, SQL, Docker, testing, and data structures.
