A Developer, Not an Agency
We build custom software for local businesses: websites, analytics pipelines, ad campaigns, and business tools. Then we prove it's working with weekly data.
From Full-Stack Developer to Local Business Partner
I'm Guillermo Barrera, a full-stack developer who got tired of watching local businesses overpay for cookie-cutter websites and marketing campaigns with no accountability.
I write real code. I build custom Next.js applications with backend APIs, Google Cloud integrations, and automated testing. I set up GA4 analytics pipelines and manage Google Ads campaigns hands-on, adjusting bids, refining keywords, and reporting results every week.
My first client, Riverton Tattoos, went from 303 sessions and 17 phone calls to 679 sessions and 86 phone calls in four weeks. I built their website, their digital consent form system, their analytics pipeline, and their ad campaigns. Then proved it all with weekly reports pulling directly from the GA4 API.
That's what I do for every client. I build it, I test it, I deploy it, and I show you the numbers every week.
