About

My Career Path

Over the past five years, I've driven next-gen technology evaluations from proof-of-concept to production, with my favorite parts being technical problem-solving and cross-functional collaboration. Whether diving into root cause analyses or presenting trade-offs to stakeholders, I've loved bridging complex technical details with real business impact.

With the rapid development of modern AI tools, I've been building custom applications to automate my personal and professional workflows. Unlike physical hardware, software and AI allow for rapid iteration and creation of incredible tools, which continues to inspire my work. I'm looking to transition into Solutions Engineering to bring that same technical rigor, AI fluency, and natural communication to customer-facing teams.

Personal

Outside of Work

Outside of my professional life, I like to be as active as possible! Most passionate about health & fitness (weightlifting, 2x marathon runner, beach volleyball) and traveling (Mexico City is my favorite). I also love NYT puzzles, learning chess, baking sourdough, and reading (science fiction, thrillers, personal development).
