👨‍💻 About Me

I'm a Software Engineer at Microsoft, working on the Microsoft Purview – Data Lifecycle Management (DLM) team, where I build and operate large-scale distributed systems that process data at petabyte scale.

  • 🏗️ I own ELC, a time-based assistant that runs against every Enterprise (E3/E5) mailbox to manage retention, deletion, and archiving of mailbox data.
  • 📊 Every three days, the systems I work on archive ~116.6 billion items (~3.56 PB) and delete ~30.6 billion items (~0.91 PB) of email data globally.
  • 🔭 Deeply interested in Distributed Systems, Platform Architecture, Backend Engineering, and Cloud Infrastructure.
  • 🎓 B.Tech, Biosciences & Bioengineering from IIT Guwahati (2020–2024).
  • 💬 Ask me about: System Design, Distributed Systems, C#/.NET, Backend Services, and Cloud-scale Data Pipelines.
