I'm Jacob Diaz-Iglesias, a full-stack software developer and entrepreneur interested in building practical, well-considered systems. I enjoy working across the stack, learning new tools, and understanding how software connects to the hardware and people who use it.
Outside of work, I'm a car enthusiast 🏎️ and motorcycle rider 🏍️, a tenor saxophonist 🎷, and an Eagle Scout ⚜️. I value integrity, determination, and above all positive intent, and I try to carry those principles into my work and life as a lifelong learner.
