About Me

I'm a software and DevOps engineer with over a decade of experience designing scalable solutions, leading cross-functional teams, and translating complex requirements into production-grade systems.

Before engineering, I studied astrophysics, where I learned to break down complex systems, test assumptions, and let the data drive decisions. That mindset still influences how I lead projects today: communicating clearly, making pragmatic tradeoffs, and building systems that are straightforward to operate and maintain.

Outside of work, I spend my time traveling the US to hike the highest points in all 50 states — a pursuit that rewards the same patience and long-term planning as found in my engineering work. It’s a steady reminder that meaningful goals are achieved one step at a time.
