Chicago roots. Product mindset.
CURRENTLY EXPLORING
Learning AI engineering.
I’m using Kiro and Codex in my workflow and diving into Claude as I learn more about AI engineering. I’m exploring how these tools can help me build better software, from planning an idea to working through the implementation.
I care about what happens
after launch.
A product isn’t finished when the code is merged. It has to work for the person using it, the team maintaining it, and the business behind it.
That’s why I like owning the whole journey. I’m as comfortable shaping architecture and untangling an API as I am refining an interaction, tracking down a production issue, or helping another engineer find their footing.
My background spans enterprise teams and founder-led products. The common thread? A practical, hands-on approach to building things that hold up in the real world.
Away from the keyboard.
I have Mexican heritage and call Chicago home. My faith is deeply important to me and a central part of who I am.
Outside of engineering, I enjoy gaming, especially Minecraft, settling in for a movie, and meeting new people. Always happy to trade game recommendations or hear what you’ve been watching lately.
