I'm Gaurav — a backend engineer with ~6 years building large-scale distributed systems in Java, Kafka and Kubernetes. Today I work on warehouse-automation platforms at Walmart Global Tech; before that I built backend for SAP's AI assistant and interned at Amazon. I did my MTech at NIT Allahabad (GATE top 1%). I've been on both sides of the interview table, so I know exactly where candidates lose offers — vague system-design answers, shaky fundamentals, and stories that don't land. I help engineers targeting SDE-2/SDE-3 roles get interview-ready fast: mock interviews with honest feedback, a plan to fix your weak spots, and a question bank covering every round. Whether you're prepping for FAANG, a product startup, or your first switch — book a session below and let's get you the offer.
