Sachin Gupta

I am a Senior Java Developer with over 14 years of hands-on experience in the trenches of enterprise software. Currently a full-time engineer at eBay, I spend my days solving scalability and reliability challenges for financial systems that serve millions of users. My technical journey has focused on high-stakes environments, including migrating 192M+ sellers to next-generation billing platforms and designing APIs that handle 80M+ daily requests. I specialize in the intersection of Java, Spring Boot, and Azure. After more than a decade of focusing on execution and architecture, I am now dedicated to sharing my "war stories" and technical insights with the broader developer community. My goal is to help other engineers navigate the complexities of modernizing legacy systems and building at scale.
