I'm a Senior Software Engineer at Paytm (One97 Communications), with 5+ years building and scaling backend systems in Java, AWS, SQL, and Redis. I've been through the interview process at three companies and know what actually gets engineers hired and promoted. I also work hands-on with AI in real production systems I've built a RAG (Retrieval-Augmented Generation) system at my company, and I use AI tools like Claude and Cursor daily to build faster and better. With companies increasingly expecting engineers to work with AI, I can help you get genuinely productive with these tools, not just buzzword-level familiarity. I help backend/Java engineers with interview prep, system design fundamentals, resume reviews, AI-assisted development, and honest career guidance practical, no-fluff advice from someone currently doing the job, not theory from a course.
