SWE II @ JPMorganChase | Low Latency Payments Engineer | Building Slydr

About

Backend engineer focused on low-latency, high-throughput distributed systems in the payments domain. At JPMorgan Chase, I’ve worked on performance-critical systems, improving throughput from 9K to 36K TPS and reducing latency by ~40% through optimized batching and messaging architectures. My work involves building scalable microservices, designing event-driven systems, and solving complex concurrency and performance challenges. I have hands-on experience with technologies like Java, Spring Boot, Kafka, Aeron, Chronicle Queue, and LMAX Disruptor, and a strong focus on system efficiency, reliability, and production readiness. I enjoy working on problems where performance, scalability, and system design intersect, and I’m currently focused on strengthening my problem-solving skills and preparing for high-impact engineering roles.
