Background

About Sourabh Singhal

I’m a Backend Engineer with 9+ years of experience building scalable, high-performance systems using Java, Spring Boot, and microservices. Over the years, I’ve contributed across the full development lifecycle — from writing clean, production-ready code and optimizing APIs to mentoring engineers and leading system design initiatives. Currently, I work as an Architect, where I help shape technical strategy, design scalable systems, and collaborate across engineering and product teams to deliver reliable backend solutions. One of the most impactful projects I’ve worked on was the modernization of eBay’s View Item page, which serves over 250 million daily requests. I contributed to the migration from a decade-old legacy architecture to a unified, modular microservices-based system. This effort resulted in a 200% increase in development velocity, a 50% reduction in time-to-ship new features, and significantly improved developer experience and scalability across platforms. While I enjoy architectural problem-solving, I’m equally passionate about hands-on leadership, simplifying complexity, and helping teams make sound technical decisions that support both engineering and business goals.
