At Samsung R&D, I build Java and Spring Boot services operating at 1B+ daily-request scale. I architected a multi-tier Redis caching strategy that cut average response time by 20%, reduced database I/O, and helped sustain 99.9% reliability during traffic surges.
I improve distributed systems through service-discovery optimization, data-serialization refactoring, JMeter load testing, monitoring dashboards, batch processing, and REST APIs. I’ve also increased JUnit test coverage by 15%, led code reviews, and mentored three interns.
Earlier at Ola Electric, I integrated real-time scooter telemetry APIs and built React and TailwindCSS dashboards for engineering and logistics teams.
