Rabindra Yadav

Software Development Engineer II, AWS · Austin, Texas

I work on the networking layer underneath AWS's managed databases: DNS architecture, IPv6 at fleet scale, and the availability machinery that keeps roughly 700,000 public databases answering queries. Lately that also means pointing AI at operations, like a retrieval tool for on-call engineers that cut incident investigation time by 74%.

I grew up in Gaighat, in southeastern Nepal, came to Texas for college, and stayed. The longer story is on the about page; the resume has the full record on one page.

Now

As of July 2026

  • Leading the work to cut DNS propagation time during RDS Multi-AZ failover.
  • Building a small iOS speech-practice app on the side, out later this year.
  • Learning distribution: how software finds its users, not just how it gets built.
