About me

Thanks for visiting my profile. My name is Nishchal Muradia. I am currently working as an SDE-3 at Oracle, and before that, I spent several years at Flipkart as a Software Development Engineer. Over the years, I have designed and built large-scale, highly scalable backend systems that power products used by millions of users every single day. At Flipkart, I worked on some of the most impactful and real-world systems — including 15-minute delivery workflows, Open Box Delivery, inventory architecture, and critical backend services that directly affected business growth, reliability, and customer experience. My work has always focused on clean architecture, performance optimization, scalability, and production-ready engineering. While transitioning from Flipkart to Oracle, I cracked multiple top product-based companies, which gave me deep insights into how big tech interviews actually work — not just DSA questions, but thinking patterns, system design depth, and engineering maturity. My next mission is simple: help others crack big tech roles with the right strategy, not guesswork. Teaching has always been a core part of who I am. My passion for teaching started in school, continued through college where I taught so many students the core computer science, and gradually evolved into mentoring working professionals and senior engineers. I’ve taught students at every level — from beginners struggling with logic building to experienced developers aiming to master System Design and Backend Architecture. I even used to teach complete computer science GATE subjects to students. So far, I’ve mentored and guided 10,000+ engineers, helping many of them secure their first role, switch to better companies, or grow into stronger engineers. If you’re someone who: Wants clarity instead of confusion Wants to think like a real engineer Wants honest guidance, not shortcuts You’re at the right place.
