Hey, I'm SepedaTua — a self-taught programmer and sysadmin in my early 40s, running CrushEdge to share the fixes I wish I'd found faster. I spend my days wrestling WordPress, WooCommerce, Linux servers, PHP, Python, and whatever else small-business sites throw at me. After years of trial-and-error (and way too many late-night server crashes), I document the solutions that actually work — safely, with backups first, and no unnecessary fluff. Outside the terminal, I'm a dad to four awesome kids, married to my best friend, and still squeezing in some video games when the house quiets down. If you're stuck on a problem, grab a coffee and let's sort it out together.
