Hi, I’m Ritik Kumar — a Senior Backend Engineer with experience building and scaling backend systems in large organizations. I’ve worked extensively with Java, Spring Boot, distributed systems, databases, and real-world production architectures. Over the years, I’ve cleared and taken multiple system design and backend interviews and understand exactly what interviewers look for at SDE-2 / SDE-3 levels. On Topmate, I help engineers with: High-Level Design (HLD) & System Design interviews Backend interview preparation (APIs, scalability, trade-offs) Resume & interview strategy guidance My focus is always on clarity of thought, structured answers, and real-world trade-offs, not textbook theory. If you’re preparing for backend or system design interviews and want honest, practical guidance — feel free to reach out.
