Software Engineer 2 @ Microsoft · Windows OS Core · AI & LLMs I build software that runs on billions of devices. Every single day. At Microsoft, I work on Windows OS Core — the most complex codebase on the planet. I write C++ deep in the systems layer and shape the future of AI-powered experiences using agents, MCP, and Skills in the LLM ecosystem. If you've ever used a Windows machine, you've used something I've helped build. Before Microsoft, I spent 3 years at Samsung, where I designed the entire auth system from scratch — SSO, OAuth2.0, SAML, OIDC — for a globally deployed product. I integrated SmartThings into the platform and watched it get showcased in Las Vegas. It won Best Project of the Year. I've cracked interviews at Microsoft, Samsung, PayPal, MakeMyTrip,Zoho and Smarsh and many other major organizations. I've gone deep in interview loops at Google, Amazon, and TikTok. I know exactly what it takes to get into top product companies — because I've done it, repeatedly. I started as an open-source contributor at SymPy, made it to Google Code Jam, and won the Facebook Open Source Immersion Award (top 1,000 globally). I didn't wait for opportunities — I built my way in. What I can help you with: 🔹 Cracking interviews at FAANG & top product companies 🔹 System design at scale — from auth systems to OS-level architecture 🔹 Building with AI agents, LLMs, MCP & Skills 🔹 Backend engineering — C++, Java, Spring Boot, Node.js, AWS 🔹 Navigating your career in tech — from campus to senior roles I've been where you are. I know the path. Let's talk.
