About

Full-Stack Web Developer

Alan Retubis

Hey, I'm Alan — a full-stack web developer who genuinely enjoys untangling messy business processes and turning them into smooth, automated systems. Over the years I've built sales & inventory platforms, project management tools, and accounting systems for real businesses that just needed things to work better.

I'm always picking up new skills to stay sharp, and I try to bring a client-first, no-nonsense approach to every project. If you've got an idea — even a rough one — I'd love to hear about it and help bring it to life.
