Hi, I'm Gonzalo. I build the calls, WhatsApp and AI agents other teams depend on.
Agencies put their logo on my work. Businesses run their intake on it. And I build a lot of it on camera, so you can see exactly how I think before we ever talk.
Three kinds of people end up here.
Calls and messages are leaking leads, and you can't see where.
I audit your phone, WhatsApp and automation setup and show you what each gap costs.
The communication audit →Your client depends on it, and you need someone who has shipped it before.
I build the Twilio and WhatsApp engine behind your product, white-label, under your name.
See agency work →You build this stuff and want to get to production faster.
Tutorials with real code, one-on-one mentorship, and soon a community to share what works.
For developers →I don't deal in hypotheticals. Here is what I've shipped.
An agency's client was counting on a contact center that kept losing calls. I rebuilt it inside Flex.
Full caller history on screen, smart routing with automatic voicemail after 20 seconds, and TaskRouter logic so one contact never opens duplicate tasks.

Real-time conversations, bulk messaging and dynamic scheduling for Elevate Automations' clients.
Production · Law firm CRMA Los Angeles law firm's whole intake, on one platform.
500 concurrent users, 20+ background jobs, two-way calendar sync. Trusted and expanding for over a year.
AI Voice · UAE telecomAI voice calls into the UAE, wired into an app already live.
Built alongside AI Boost's telecom and frontend teams, without breaking what was there.
"Whatever the project takes, Gonzalo either knows how to do it, or he'll learn how with efficiency. It was an absolute pleasure working with him."
Every engagement starts with the communication audit.
I go through your phone, WhatsApp, SMS and the automations you already run, the way I go through my own production systems. Then I show you where the money is leaving and what it costs to stop it.
Paid and limited. I confirm I can actually help before I send a fixed quote.
I build these systems on YouTube, failures included.
Real builds with Twilio, WhatsApp and AI agents, in Spanish. Each one gets an English write-up on the blog.

Coming soonA space for devs building communication and AI systems: share what works in production, and find the next job or project.
What people ask before we talk.
I build the communication systems other teams depend on: Twilio voice and contact centers (Flex), the WhatsApp Business API, AI voice and WhatsApp agents, and the automations around them. I work with businesses, with agencies that resell the work under their own brand, and with developers through tutorials and mentorship.
