Cloud Platform Architect | AWS, Kafka, Distributed Systems | Building scalable, multi-region backend platforms | 12+ Years Building High-Throughput, Low-Latency Platforms

About

I design and build backend and platform systems that power real-world products at scale. With 12+ years of experience in Java, distributed systems, and event-driven architectures, I specialize in building scalable product backends that are reliable, observable, and easy to evolve. My work spans architecting microservices with Kafka & Spring Boot, driving system modernization for BFSI and SaaS platforms, and leading teams to deliver measurable outcomes — improving throughput, reducing latency, and enhancing uptime. Recently, I’ve focused on connecting AI-driven workloads with traditional distributed systems, designing data pipelines and inference-serving platforms for next-generation product experiences. I thrive in product organizations that value impactful engineering — where architecture isn’t an ivory tower concept, but the backbone of real, scalable products.
