About

I am passionate about designing and architecture of building highly scalable Cloud platforms and optimize high-performance systems that handle millions of transactions daily, blending 15+ years of expertise in cloud platforms (Azure, AWS, GCP), microservices, and big data. Past Key contributions: • Cutting cloud costs without compromising performance (e.g., saved $20M/year at Microsoft by rearchitecting Azure IoT Hub’s CosmosDB CQRS pattern and scaling strategy). • Building scalable, event-driven platforms (e.g., designed KYC/Merchant Data systems at Pine Labs handling 10K+ TPS). • Leading teams to solve complex technical challenges while fostering innovation. Why work with me? • Azure IoT & Cloud Native: Proven track record in designing Azure IoT solutions, COGS optimization, and disaster recovery (reduced RTO/RPO by 50%). • Full-stack architect: Proficient in Java/Scala, Spring Boot, Kafka, CosmosDB, and K8s, with a focus on high availability and observability (Prometheus/Grafana/ELK). • Mentorship: I thrive on elevating teams through technical roadmaps and hands-on guidance. Beyond work, I experiment with emerging tech (POCs!) and capture the world through photography. 🔗 Let’s connect to discuss scalable architecture, cloud cost hacks, or trending tech!
