Justin Schellenberg

Lead Developer & Founder

Justin Schellenberg didn’t take the usual path to becoming a digital strategist. His training ground? The wild, unfiltered internet. Self-taught, scrappy, and sharp as a tack, he cut his teeth by reverse-engineering problems most tech pros wouldn't touch. While others read manuals, Justin rewrote them in real time, because he had to.

But the real turning point came when he saw what was broken from the inside.

Working inside a big agency, he witnessed small business owners being overcharged and underserved. Paying premium rates for junior developers. Endless back-and-forth. Confusion. Delays. Frustration. He knew there had to be a better way: faster, clearer, more human.

So he bet on himself. And he built FireNet Designs.

Today, Justin leads a tight, high-performance team that makes tech disappear for busy business owners. No fluff. No jargon. Just lean, fast, end-to-end web support that actually delivers, whether it’s redesigning a Shopify store, building custom apps, or untangling tech messes that no one else could solve.

Justin’s superpower? Turning chaos into clarity, and giving business owners their time (and sanity) back.

This isn’t just code. It’s a mission. Built from the ground up to help you grow, without getting burned again.
