Guerrilla Digital

Milwaukee Web Development and Audio Engineering

This is the personal audio & visual portfolio of Wisconsin native, Martin Defatte.

I’ve worked as a graphic designer, package designer, web developer, producer, engineer, and remixer — for record labels, agencies, and bands alike. I’m a natural tinkerer and problem-solver, driven by curiosity and a love of figuring things out.

In my spare time, I explore that same DIY spirit through hands-on projects: soldering mic preamps, building guitar pedals, circuit bending toys, and experimenting with cassette loops. Lately, I’ve taken that curiosity into a new hobby — restoring and modifying vintage 1990s mountain bikes into modern “rat bikes” (you may have heard them referred to as “café cruisers”, “pub bikes”, or “dad bikes”).

I always have a few passion projects in the works, but I’m open to the right freelance opportunity — or, if your team is looking for a full-time WordPress developer, let’s talk. I’m always interested in the next good challenge.

Without the exceptional website that Martin has built for me and maintained over the years, my business wouldn’t be half as efficient or successful as it has become. His attention to detail both behind the scenes and on the surface are a recipe for great success. He’s also very responsive to changes, updates, and maintenance when needed.
