Austin, Texas · Independent studio since Windows 95
Hi, I'm Guillermo — a problem solver with 20 years of building software. Every project starts with a paid assessment, then a fixed-price proposal, then a real product on your own domain. After launch I stay around as the developer you can call on a Tuesday.
A note from the studio
Pictured: out on the water — the only place I let work wait.
I started writing software on a beige tower running Windows 95. Since then I've shipped desktop apps, mobile apps, Shopify stores, WordPress plugins, internal dashboards for agencies, Google Assistant experiments at Jam3, and full product builds for startups across the US, Europe and Latin America.
Most small businesses don't need an agency, a 12-week sprint, or a Notion full of slack channels. They need one developer who can listen this week, scope the next, and pick up the phone when something needs a tweak.
That's what I do here, on my own time, outside of my agency — so the price stays honest, the relationship stays personal, and your product stays alive long after the launch screenshot.
What I make
I keep the offer narrow on purpose. Two tracks, both fixed price after a paid assessment, both with optional monthly maintenance so your site doesn't quietly rot six months after launch.
Editorial, custom-designed sites that actually convert — like the venue and catering brands further down the page. Built for owners who want a place that feels like theirs, not a Squarespace template.
The boring software that quietly makes a small operation profitable. Order intake, inventory, custom CRMs, scrapers, daily reports — built around the way you already work.
How we work
No discovery deck, no sprint zero, no "let me sync with my PM". Every project begins with a paid assessment so the scope is real before we write a single line of code.
A paid 1–2 day audit (US$500) where I dive into your business, your stack and what you actually need built. You leave with a clear written read-out — yours to keep, even if we don't work together.
A single, short doc grounded in the assessment: scope, deliverables, one number, one timeline. No retainers buried in PDFs, no change-order surprises later.
I build it on your domain, share progress live, and ship to production. Average build window is 1–3 weeks. You don't pay anything more until you've seen it working.
Pick a monthly care plan (or don't). Hosting, content tweaks, bug fixes, small new features — handled by the same person who built the thing.

Scrapes local businesses, scores each lead with Claude 4.5, then closes deals with a Vapi voice agent — all tracked in a single dashboard with ROI per niche × city.
Private build · case study on request
An editorial site for a hill-country hacienda, a tequila-tasting product page, and a private dashboard where the López family confirms inquiries, tracks bookings and reviews chatbot leads.
A bilingual landing for a flavor-first caterer, three-tier dinner menus with per-guest pricing, and a private admin where the chef edits dishes and generates a QR code clients scan at events.
A handful of other projects live quietly inside companies — agencies, e-commerce stores, Web3 startups. Happy to share case studies on a call.
In their words
Guille shipped our internal order tool in a week. Three years later it's still running, and he's still the person we text when something breaks.
We needed someone who could think like a product person and code like a senior. We got both, in one human, with a fixed price and no agency overhead.
He rebuilt our WooCommerce → BuddyPress flow in two days. What our previous developer estimated at six weeks.
Honest, fixed pricing
Every engagement begins with a paid assessment so the scope is real before we commit. From there I send a single fixed-price proposal. Maintenance is optional, monthly, and cancellable any time.
