About

I am a Senior Software Engineer with 9+ years of experience building scalable backend and distributed systems. I specialize in designing high-performance, low-latency systems using microservices and event-driven architectures. My work focuses on solving complex engineering problems at scale, ensuring reliability, efficiency, and performance. Key areas of expertise: • Distributed Systems & System Design • Backend Engineering (Java / Python / Go) • Cloud Platforms (AWS / GCP) • Event-driven architectures (Kafka, messaging systems) • Microservices & API design In my recent work, I have: • Built and scaled systems handling millions of requests per day • Improved system performance and reduced latency • Designed resilient and fault-tolerant architectures I am passionate about building systems that scale and continuously improving engineering practices. Open to opportunities in Backend Engineering and Distributed Systems.
