Hey there, I’m Sumit! I’m a Backend Engineer who enjoys helping developers build scalable systems and unlock their career potential. I focus on the design and rollout of high-throughput backend architecture, whether it's for massive infrastructure handling high-volume national tax data, or cloud-native integration layers for global retail brands. Currently at IBM, I am working on a major containerization and migration project for a leading international bank, moving legacy systems to modern Java 21 and hybrid cloud architectures while leveraging cutting-edge AI tools to accelerate the process. Over the years, I’ve had the chance to work with major technology powerhouses like Infosys and IBM, solving complex problems in areas like microservices migration, real-time data streaming with Kafka, and cloud resource optimization. My day-to-day engineering toolkit is built entirely around production-grade Java, Spring Boot, Docker, and Kubernetes. Outside of my core engineering work, I love giving back to the developer community. I use my firsthand experience navigating intense technical interview loops to mentor aspiring and mid-level engineers, helping them master system design, optimize their resumes, and build the confidence needed to clear top-tier tech rounds. You can count on getting practical, fluff-free advice rooted in real production experience. If you're preparing for your next backend role, looking for a realistic mock interview, trying to crack microservices concepts, or just want some honest career guidance. let’s connect!
