What I'm looking for

I seek backend roles focused on scalable systems, performance optimization, observability, and cloud-native practices, with opportunities for impact and growth.

I am a backend software engineer with 4+ years designing and delivering scalable Java/Spring Boot microservices for fintech and enterprise environments. I focus on improving API latency, scaling distributed systems, and building reliable production services using Kafka, Redis, and AWS.

Throughout my career I have driven measurable performance gains — for example, reducing API latency by up to 75%, boosting inter-service throughput by 35%, and improving test coverage and reliability by 25%. I combine strong system design, observability practices, and CI/CD automation to ship robust, maintainable systems.

I am an immediate joiner open to relocation within the United States and I bring hands-on experience integrating ML inference services, implementing secure auth flows, and leading small engineering teams to deliver high-impact projects.
