About

Senior Software Engineer with 6+ years of experience designing and scaling distributed, event-driven systems and high-performance full-stack applications used across 20+ countries. I specialize in backend architecture, system design, and frontend performance optimization using Java, Spring Boot, Apache Kafka, PostgreSQL, Redis, Node.js, and Next.js. Passionate about building resilient, low-latency systems that perform reliably under real production load. Experienced in architecting Kafka-based distributed pipelines, reactive systems, and scalable platforms using DDD, idempotency, and observability-driven engineering practices. One key milestone includes delivering a 171x performance improvement through reactive order processing architecture. I’m deeply curious about how large-scale systems behave under load, failure, and scale. I regularly build experiments, break things locally, and share practical lessons from distributed systems, production engineering, and modern backend infrastructure. Beyond coding, I actively mentor engineers on system design, frontend performance, and engineering best practices to improve scalability, reliability, and delivery predictability. Design. Build. Scale.
