About

SDE 2 (Associate) at Goldman Sachs with 5+ years of experience building large-scale, distributed backend systems. Previously SDE 3 at Walmart, where I designed scalable microservices, real-time data pipelines, and backend platforms used by millions.I specialize in Java (OCAJP certified), Spring Boot, J2EE, Kafka, and NoSQL systems. My recent work is deeply focused on cloud-native distributed systems, event-driven architectures, resilient microservices, consensus patterns, and high-throughput data processing.Currently working extensively on AWS Cloud, building and operating systems powered by: • Kafka Streams & Apache Flink • Amazon MSK (Managed Kafka) • Amazon ECS, EC2, Lambda • Infrastructure-as-Code with AWS CDK • Event-based architectures & real-time streaming workflowsI enjoy solving complex engineering problems with clean architecture, scalable design, and production-ready code. Passionate about observability, performance engineering, and building platforms that scale across teams and organizations.Actively upskilling through the Cloud Computing Specialization (University of Illinois) to deepen expertise in distributed consensus, fault tolerance, MapReduce ecosystems, and large-scale cloud design.Open to roles involving deep tech, backend platforms, real-time systems, and distributed infrastructure.
