About

I'm Davin Young — a Staff Software Engineer and founder based in Southwest Florida. I like building things end-to-end: backend services, cloud infrastructure, storefronts, and the glue in between.

I've co-founded SecureTap (a blockchain authentication startup) and Sunset Vista Co. (a digital agency serving SWFL businesses). Along the way I've picked up two granted US patents.

I'm most at home deep in infrastructure — debugging Docker containers at 2am, setting up CI/CD pipelines, or standing up new services on AWS. I care about systems that are reliable, well-tested, and simple enough to hand off.

When I'm not coding, you'll find me tweaking my home lab or working on electronics projects.
