About

Hi, I’m Vamsi. I’m a backend engineer with 5+ years of experience building and scaling distributed systems in high-traffic environments. I currently work at Salesforce, where I contribute to backend platforms powering Service Cloud and Omni Routing. My core strength lies in designing reliable, scalable backend services using Java and Spring Boot, with a strong focus on correctness, performance, and long-term maintainability. I’ve worked across domains like e-commerce, industrial networking, and IoT, solving problems related to scale, latency, and system reliability. What I work on Backend systems at scale (Java, Spring Boot, Microservices) Event-driven architectures (Kafka) Data-intensive systems (Postgres, MongoDB, Neo4j) Cloud-native development on AWS Beyond the job: I mentor engineers on System Design, Java, and DSA via Topmate — 100+ sessions, 90%+ placement rate. I write here about what actually happens in senior-level interviews, not what interview prep books tell you.
