Working in an in-house infrastructure setup has given me deep exposure to real-world backend challenges — from debugging production issues to optimizing performance and ensuring system reliability. My areas of focus include: Backend system design and architecture Database performance and query optimization Scalability patterns like rate limiting, caching, and load handling 💡 I can help you with: Cracking backend interviews (Java, Spring Boot, SQL) Understanding system design in a practical, simple way Debugging mindset and real-world problem solving Strengthening backend fundamentals I enjoy breaking down complex engineering topics into simple, practical insights that actually help in interviews and real jobs.
