I’m a backend engineering professional with extensive experience building scalable, high-performance systems in production environments. Over the years, I’ve worked on designing and optimizing distributed systems, payment flows, and real-time data processing applications, with a strong focus on reliability, performance, and clean architecture. My core expertise lies in Java, Spring Boot, system design, and solving complex data structure and algorithm problems. I’ve been deeply involved in architecting microservices, improving system scalability, and troubleshooting critical production issues such as latency bottlenecks, memory leaks, and consistency challenges. I’m particularly passionate about system design interviews, backend architecture, and helping engineers grow in their careers. I enjoy breaking down complex concepts like distributed systems, concurrency, caching strategies, and database design into simple, practical insights. On Topmate, I help with: * System design interview preparation (real-world scenarios) * Backend engineering guidance (Java, Spring Boot, microservices) * Debugging production issues (performance, memory, scalability) * Career guidance for senior engineer / tech lead roles If you’re preparing for product-based companies or aiming to move into senior/lead roles, I’d be happy to help you with structured guidance and practical insights from real industry experience.
