I design and build scalable backend systems, REST APIs, and web applications with a focus on performance, reliability, and maintainability.
Currently handling system architecture at Weekmotion, optimizing core workflows to safely scale data pipelines, media delivery, and micro-transactions under high concurrency.
📊 Reduced p95 API latency from 380ms to 220ms by restructuring MySQL composite indexes and implementing distributed Redis caching layers under peak traffic spikes.
⚡ I focus on building simple, fast, and maintainable web systems that solve real-world problems.
