Hi, I’m Harshit — an SDE3 at Amazon with 12+ years of experience building and scaling distributed systems across Amazon, Paytm, and Novell. At Amazon, I’ve worked on high-impact systems in Transportation and Payments, including launching BNPL integrations with Grab and Atome (Amazon Singapore) and building global platforms for delivery station operations. I specialize in backend and distributed systems, and over the years, I’ve taken 100+ interviews at Amazon, primarily focusing on system design rounds for SDE2, SDE3, and SDM roles. I work with experienced engineers (3–8 YOE) who are aiming for top product companies like FAANG and want to: Master system design (HLD/LLD) with real-world depth Crack high-bar interviews (SDE2/SDE3/SDM) Get actionable feedback through mock interviews Improve resume and overall career positioning My approach is deeply practical — focused on how systems are actually built and evaluated in top-tier companies, not just theoretical concepts. If you’re serious about leveling up and want honest, high-signal feedback, feel free to book a session.
