About

Back in 2018, I began my journey as a mid level backend engineer at Wellthy where I'm now an Engineering Manager on a team that has focused on projects from database optimization to implementing design systems. Prior to that, I was in the world of business operations at Interbrand, helping automate their business processes.

I enjoy systems of any kind, from an internal business process, to a codebase, and even macroeconomics.

Aside from programming, I love dancing. I go out often on the weekends, and if you're familiar with Berlin, and Berghain in particular, I went every three months at one point in life.

I also love baking and often bring blueberry muffins, chocolate chip cookies, and apple pie to the office (if you weren't sold on working with me yet!). I'm attempting to get my apple strudel perfected, all tips are welcome!
