I’m a Senior Software Engineer at Microsoft (Teams) with ~7+ years of experience building large-scale backend systems used by millions of users. I’ve worked across recommendation systems, notifications, search, and reliability-critical services, and I currently lead backend components for personalized feed generation in Microsoft Teams. I actively handle system design, scalability, reliability, and live-site ownership, including incident management, RCAs, and performance optimizations in production. I’ve also been a privacy and security champion, reviewing real-world backend designs beyond just theory. As a mentor, I help engineers: Crack SDE interviews (DSA + System Design) with structured thinking Learn how to approach LLD & HLD questions like an interviewer expects Improve backend engineering depth (APIs, databases, microservices, scaling, trade-offs) Navigate career growth from SDE1 → SDE2 → Senior roles If you’re preparing for product-company interviews or want practical guidance grounded in real production systems (not just textbook answers), I’d be happy to help.
