Software Engineer · Now

Building the platforms a major mortgage lender runs on.

PennyMac is one of the largest mortgage lenders in the U.S. I'm on the platform team that builds and runs the systems the whole business depends on, so my work touches every application the company uses to keep its services running.

What I work on

  • Developer tools the engineering team uses every day
  • Telemetry built from the ground up, so problems show up before anyone has to go looking
  • Serverless infrastructure on AWS
  • Bringing AI into how the whole engineering org works

Why it matters

When the platform is solid, every team at the company can ship faster, and the people paying their mortgage never have to think about it.

Next project

International Medical Devices Inc.

AI that shows patients their results before surgery.

Let's build something.
