What I'm looking for

I’m looking for a role where I can architect resilient Java microservices, optimize latency and throughput, and drive observability and reliability improvements—while mentoring engineers to ship clean, scalable systems on cloud-native platforms.

I’m a results-driven Senior Java Backend Developer with 7+ years of experience architecting and scaling distributed microservice systems handling 150K+ transactions per day. I build event-driven architectures with Apache Kafka, apply fault-tolerant design patterns like Saga and Strategy, and focus on production-grade performance.

In my current role, I architect core microservices for a distributed transaction platform, using Kafka batch optimization and Redis pipelining to reduce end-to-end transaction latency by 35% and improve throughput by 40%. I strengthen reliability with Resilience4j (circuit breakers, retries, bulkheads) and raise operational visibility through Spring Actuator, Micrometer, Prometheus, and Grafana—cutting MTTD for incidents by 50%.

I also enjoy owning end-to-end product outcomes: I independently architected and shipped a production-grade School ERP using Firebase Authentication, Firestore (NoSQL), and Vercel deployments with Git-based CI/CD. I’m passionate about performance optimization, system observability, and mentoring engineers to deliver clean, maintainable code at scale.
