Saurabh Singh

About

Engineering leader and platform specialist with 10 years of backend and platform engineering experience across Java, Spring Boot, Kafka, Redis, Camunda BPMN, AWS, and distributed microservices. Proven track record modernizing monoliths into independently deployable services, building event-driven systems, reducing operational noise, and leading cross-functional engineering teams through delivery.

Story

I have spent a decade building backend and platform systems where reliability, throughput, and operational clarity matter. My work spans insurance transaction platforms, cross-chain infrastructure, crypto custody, and large-scale telecom systems.

I am most effective at the intersection of architecture and delivery: decomposing monoliths without breaking production contracts, designing event-driven services that teams can operate confidently, and building the observability and automation layers that keep platforms healthy.

As a technical lead, I focus on hiring strong engineers, raising engineering standards through reusable patterns, and creating environments where teams ship incrementally with measurable impact.
