What clients say
“With 2-3 weeks of working with Brandon the phone starting ringing off the hook. I have had the slowest business year in 9 years until Brandon helped me turn things around with a new website and ideas to get the clients back using my website. I am so happy to be back in business again!!”

We build the smallest system that solves the problem — and reach for AI only when it's the right tool, not the fashionable one.

Principal engineering without the agency relay race.
Fullspec Studio is led by Brandon Johnson — a principal engineer with roughly 19 years building distributed systems in regulated environments, payments infrastructure, and developer platforms at companies like Moov Financial and Cricut.
At different points across those years he's been the specialist on each band of the spectrum — infrastructure, data, backend, frontend, in turn — going deep on one part of the stack at a time. The full-spectrum range is real depth earned in each layer, not breadth spread thin.
He does the work himself; when a project needs a dedicated specialist, he brings in a trusted collaborator rather than a bench of juniors. The studio stays small on purpose — so the person who scopes your project is the one who ships it.
