Build software that
actually ships
WebApps, mobile apps, and AI — built to your exact specs. No agencies marking up junior devs, no freelancers who ghost. Just a senior builder who treats your budget like it's his own.

I charge for the result.
Agencies bill hours. Freelancers bill tasks. Nobody bills for what actually matters: that it works, that it sells, that it lasts.
The project that never ships
Six months in and they're still "almost done." Every week, a new blocker. Every blocker, a new invoice. And when you ask for a real date, the answer is always "soon." Meanwhile, your window is closing.
The freelancer who disappears
Week one: fast replies, big energy. Week four: excuses. Week eight: nothing. The code is half-done, the money is gone, and you're back to square one — except now you're behind, broke, and burned.
The agency that sells you lock-in
Beautiful deck. Impressive proposal. Then they deliver something your team can't touch, that breaks without their support, and that you keep paying to maintain. They didn't build you software. They built you a subscription to themselves.
That's how I work.
"When something breaks, I don't send a report. I fix it."

AI That Earns Its Keep
Agents, automations, and chatbots that plug into what you already run. AI that cuts your team's grunt work in half — without replacing the people who matter.
Less repetitive work. More output.

I'm Saul González —
I build software. I understand business.
Most software fails because the developer only speaks code. I speak both. 15+ years shipping products with teams across Puerto Rico, the US, Chile, and Argentina. Co-founder of Puny.bz — 1,303 active businesses, including the Puerto Rico government, run on what we built.
I don't start with a tech recommendation. I start by figuring out what success actually looks like for your business. Then I build backwards from there — no fluff, no padding, no features you'll never use.

How it works
From idea to running — 3 steps
Free 30-min call — no pitch
You talk, I listen. No deck, no sales script. I ask the questions that help me give you a straight answer: what this actually takes and whether I'm the right person to build it.
A plan that makes sense
I send you a clear roadmap: right tech stack, honest timeline, real cost range. Everything you need to make a decision — before you spend a dollar.
We build — or I find who should
If I'm your best option, we ship. If someone else is a better fit, I'll say so and make the intro myself. No strings, no runaround.

Dnuevo Coffee Specialty

signups on launch day
zero paid acquisition
$0
ongoing reach cost
own channel, no ad spend
The challenge
Dnuevo wanted to stop renting their audience from Instagram and own a direct line to their best customers — without paying for reach every single time.
What we did
We built a digital loyalty experience that lives in Apple Wallet and Google Wallet. No app download required. Launched first with Dnuevo, then rolled out to all Puny.bz merchants.
The result
400+ customers signed up the day it went live. By the next morning they were already redeeming points. Dnuevo now owns their customer channel — permanently, at zero cost.
"The next day people were already using it and claiming their points. It was a complete success."

The challenge
Their website was a digital brochure — no leads, no conversions, no way to track ROI. They needed government agencies and enterprise buyers to come to them.
What we did
Rebuilt the platform ground-up: technical SEO, segment-specific landing pages for each buyer type, and an automated quote request system tied to their sales workflow.
The result
Zero to 40 high-value inbound leads per week in under a month. The channel paid for itself immediately and is now their single biggest source of new business.
"Saul turned it into our best source of clients."

The challenge
Puerto Rico had no platform that let micro and small businesses launch their digital presence in minutes — without agencies, without code, without prohibitive costs.
What we did
I co-founded Puny.bz and led the full technical build: multi-tenant architecture, no-code builder, local payment integrations (ATH Móvil, Stripe), and enterprise modules for auto dealerships.
The result
$260K ARR. 1,303 active businesses in 19 countries. 8 auto dealerships through an Inv360 partnership. Puerto Rico's government as a client. Parallel18 alumni.
"We built something that had never existed in Puerto Rico. What surprises me most is the traction — and we're just getting started."
