Hi, I'm Roger.
Nice to meet you.
I'm a solo engineer in the San Antonio area. What I enjoy most is creating useful products that make life easier for both myself and the people who use them.
Where I've Worked
Healthcare, government, healthcare, government again, I promise there's no pattern here (or maybe there is). Bouncing between two of the most heavily regulated industries out there taught me more about building secure, compliant software than almost anything else could.

Roger was absolutely fantastic! He was incredibly knowledgeable and immensely helpful. Our website was on the verge of going down, and without Roger's swift action, it would have.
Roger did an amazing job with our digital marketing. They were professional, creative, and helped boost our online presence significantly. Highly recommend their services!
Roger was responsive, creative, and easy to work with, making the entire process smooth. I'm extremely satisfied with the outcome and highly recommend!
A Solo Developer
Don't get me wrong, working on a team has its own kind of flow. But there's something therapeutic about going solo, it gives me the space to think, get creative, and experiment freely.
I like getting into the weeds, figuring out how something works, then rebuilding it better. That mix of curiosity and stubbornness is probably what keeps me doing this for a living.
My main tech stack:
Products I've Built
A couple of SaaS products I've designed, built, and shipped on my own, from idea to production.
AuthTally
A public voting app built for on-site events. Attendees cast votes on the spot without downloading an app or logging in, and results stay secure and tamper-proof in real time.
