Welcome to my site—my little corner of the internet where I share what I’m building, learning, and experimenting with.


Writing

Notes on engineering, leadership, and building software. Just me thinking through problems out loud. Head over to my blog for the latest.

Projects

Building and shipping small, focused creations—like tools, games, or tutorials—gives me a real burst of energy. The feeling of greenfield coding is just so friggin awesome. I learn best by diving in and getting my hands dirty, turning ideas into working prototypes to truly understand how things tick. Honestly, these days I'm so all-in with work that side projects don't get the love they used to—but the ones below still hold up.


Sci-Fi

I’m a lifelong sci-fi fan, and these days I love “vibe coding” stories with ChatGPT. We do these creative jam sessions where I throw out ideas and the LLM riffs back with scenes, twists, and new angles. We take turns building the story — I edit, it generates — until a full narrative takes shape. Together, we craft fun, fast-paced, tech-driven sci-fi, basically writing exactly what I want to read.

  • 🚀 Trajectory – My first experiment co-writing a space sci-fi story with AI

Education

San Francisco City College

Computer Science

After wrapping up my undergrad in History and spending a couple of years in the Peace Corps, I decided to make a hard left turn into software engineering—honestly, one of the best choices I’ve ever made (second only to marrying my wife). I went all-in at San Francisco City College, stacking my schedule with C++, Databases, Web Development, Software Engineering, Unix System Programming, and Data Science. Somewhere along the way, I even became a TA for Intro to C++, which was exactly as glamorous as it sounds (lots of debugging semicolons and “why won’t this compile?” moments).

While City College was my main base, I wasn’t shy about branching out. I picked up additional coursework at UC Berkeley Extension and later dove into online platforms like Coursera and Code Academy to keep sharpening my skills. Piece by piece, these classes added up to a “degree-ish” equivalent in Computer Science. Spoiler: it worked.

After more back-and-forth with Disney HR than I ever expected, my patchwork of studies was officially good enough to land me the engineering role I wanted. That mix of formal instruction, side-courses, and hands-on teaching not only gave me the technical foundation I needed—it also taught me that persistence, curiosity, and a healthy sense of humor are just as valuable in engineering as knowing your way around a for loop.
