Hi, I’m Rohit. I’m a Backend Engineer with a passion for designing systems that scale to millions and helping engineers navigate the leap to Senior/Principal roles. My Expertise: Backend Mastery: Deep expertise in Java, Spring Boot, and Microservices. Architecture: Distributed systems, NoSQL/SQL database internals, and Caching strategies. Design Excellence: Mastering LLD (Low-Level Design) and SOLID principles to write production-grade code. Over the years, I’ve realized that the gap between a Senior and a Principal Engineer isn't just coding speed—it's System Design and Leadership. I’ve mentored engineers to bridge this gap, helping them land offers at companies like Atlassian and MongoDB. Whether you’re struggling with "vague" system design prompts or need a brutal resume audit, I’m here to provide the high-signal feedback you won't find in a textbook.
