02 — Skills & About

I've spent 7+ years in a Microsoft-first environment — C#, ASP.NET, SQL Server, jQuery, and Azure are my daily tools. I own the full DevOps and testing lifecycle end to end, and bring React and Node.js to the table as well.

Outside of work I love deep sea fishing — catching yellowtail on the open ocean is one of my favorite ways to recharge. I also boulder and play tennis. Always up for a challenge on and off the keyboard.
