Hello, I'm Nitish. I graduated from Maulana Azad National Institute of Technology, Bhopal (NIT Bhopal) in 2021 with a degree in Computer Science. I began my professional journey at Amazon as a Software Development Engineer (SDE 1) and was later promoted to SDE 2, where I worked on building scalable and reliable systems. Currently, I am a Senior Software Engineer at Walmart, designing and delivering high-impact solutions at scale. My expertise includes: Data Structures & Algorithms (DSA): Cracking coding interviews, problem-solving strategies, and competitive programming. System Design: From fundamentals to advanced concepts, preparing for interviews, and real-world applications. Interview Preparation: Resume building, behavioral interviews, and mock interviews (Amazon Leadership Principles, FAANG-style). Career Guidance: Roadmap for entering top tech companies, switching roles, and accelerating career growth. Software Engineering Best Practices: Writing clean code, scalable architecture, design patterns, and code reviews. I actively mentor aspiring engineers, helping them strengthen their problem-solving mindset, master system design, and confidently navigate interviews at top product-based companies.
