Austin, Texas · Custom software developer · 20+ years building tools

I turn operational chaos into tools that pay for themselves.

Hi, I'm Guillermo. I've been obsessed with building tools since I was a kid in front of a Windows 95 tower — that obsession is what pushed me into this career and what keeps me in it, 20+ years later. I work with one client at a time, scope is real before a line of code is written, and the price is agreed up front.

A note from the studio

Guillermo Figueroa Mesa at WordCamp Europe, Porto

Pictured: out on the water — the only place I let work wait.

Twenty-plus years of code, one stubborn habit: solve the puzzle in front of me.

For twenty-plus years I've built the software behind other people's businesses — the site that captures a lead while you're on stage, the tool that stops orders from getting lost, the admin panel that lets a non-technical owner update prices without paying a developer for a typo. I've done it for startups and small teams across the US, Europe and Latin America — including work on Google Assistant experiences at Jam3.

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.

I don't build software because it's trendy. I build it because solving the puzzle in front of me is the only thing that has held my attention for twenty-plus years. It's the reason I studied this career, and the reason I'm still in it.

What I solve

Two problems. One human building the fix.

I keep the offer narrow on purpose. Every engagement is scoped and priced up front after a paid assessment, and every build comes with optional monthly care so your tool doesn't quietly rot six months later.

Track 01 · Customer-facing01

The website your business deserves — one that answers the phone when you can't.

Editorial custom sites that turn a visitor into a scheduled call, a booked event, or a paid order — while you're doing something else. Not templates. Not the same site your competitor already used.

  • A public site that captures leads while you sleep
  • Booking, WhatsApp, SMS or Calendly on the page
  • Ranked on Google without you having to babysit it
  • Edit typos and update pages yourself — no developer needed
From $3,780Talk to me →
Track 02 · Back-of-house02

The tool that stops your business from running on WhatsApp and memory.

A private tool that takes the chaos out of your operation — orders, inventory, bookings, team handoffs. Built around how you already work, not how a subscription tool wishes you did.

  • A private tool tailored to your daily flow
  • Connects to your existing systems — payments, e-commerce, whatever you use
  • Replaces copy-paste, spreadsheets and manual updates
  • Each teammate sees only their part — no accidental deletes

How it works

A short, honest path from problem to live.

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.

  1. 01Step

    Assessment

    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.

  2. 02Step

    Proposal

    A single, short doc grounded in the assessment: scope, deliverables, one number, one timeline. No retainers buried in PDFs, no change-order surprises later.

  3. 03Step

    Build

    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.

  4. 04Step

    Care

    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.

In their words

Quiet praise from the people I've actually shipped with.

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.
Founder · Foodhuggers

We needed someone who could think like a product person and code like a senior. We got both, in one human, with a clear price and no agency overhead.
