What I'm looking for

I’m looking to lead microservices and event-driven backend builds—owning reliability, performance, and security—while mentoring teams and using data-driven observability and modern cloud practices to deliver measurable impact.

I’m a Senior Java Engineer with 5+ years architecting microservices platforms across fintech, HRM, and ecommerce. I’ve delivered measurable impact—70% fewer production incidents, 75% performance gains, and 68% faster deployments—by designing reliable systems and tightening operational rigor.

I specialize in Spring Boot and Java, with React, Kafka, and cloud engineering on AWS and Azure. I build systems that process 50,000+ daily transactions with 99.9% uptime, and I’m known for mentoring engineers and driving strategic technical initiatives.

In my current role, I engineered a high-concurrency HRM platform with event-driven Apache Kafka for real-time attendance, added JWT + role-based access control, and improved resilience through AWS/EKS containerization and observability (CloudWatch, Prometheus, ELK, Zipkin). I also integrate GenAI into development and product workflows using GitHub Copilot/Claude Code and LLM APIs embedded into Spring Boot services to enable semantic search and automation.
