Hi, I’m Bishnu 👋 I’m a Software Engineer with 4+ years of experience building distributed, scalable backend systems and full-stack applications. Along the way, I’ve solved 1000+ LeetCode problems and reached LeetCode Knight (2059 rating) — all while working full-time. I come from a non-CS background and once struggled to write even a simple program. Through consistent effort, disciplined practice, and a structured roadmap, I was able to turn things around and build a career in software engineering. I don’t believe in shortcuts, hype, or “guaranteed placement” claims. My approach focuses on clarity, strong fundamentals, consistency, and interview-realistic preparation. I currently help entry- to intermediate-level engineers, freshers, and non-CS candidates — who feel stuck despite putting in effort. This includes guidance on DSA strategy, interview preparation, resume positioning, and job switches (including service-based to product-based and non-IT to IT transitions). If you’re looking for honest, practical guidance from someone actively on the journey, feel free to book a session.
