Gizmo · Brownsville, TX

Most people around the Rio Grande Valley know me as Gizmo — and now you know where the domain comes from.

I was born and raised in Brownsville, Texas, and I’ve been into technology since 2005. Before I even finished high school, I had already started my first company — and I’ve been building, fixing, and occasionally breaking things in IT ever since.

So what is this site? gizmo421 is a home for the tools I actually use. Over the years I kept a little collection scattered across different websites — password generators, calculators, converters — and I got tired of hunting them down, wading through ads, or creating an account just to convert a unit. So I built my own versions and put them all in one place.

Everything here runs right in your browser. Nothing you type gets uploaded, tracked, or sold. No accounts, no clutter — just tools that work.

I also run Wired In IT, an IT support company serving the Rio Grande Valley — Brownsville, Harlingen, San Benito, McAllen, and everywhere in between. If your business or household needs tech help, that’s where I do that work.

Whether you’re a student at UTRGV, a small business owner in Edinburg, or just someone who needed to split a tip at 2am — I hope this site saves you a few clicks. It’s free, it always will be, and it’s made right here in the RGV.
