About

I'm a Senior Software & AI Engineer with 7+ years of experience building communication systems and the platforms around them, on Twilio, Laravel, Python and n8n.

Most of my work is for US-based companies whose operations run on calls and messages: a Twilio Flex contact center for an agency's client, a whitelabel WhatsApp platform other agencies resell, and a law firm CRM that holds up under 500 concurrent users.

I don't build demos. I build systems that run when someone picks up the phone.

From startups to enterprises, I provide Twilio-based solutions that optimize customer engagement, automate processes, and improve operational efficiency.

Frequently asked questions

Yes. I register the brand and the campaign, write the use case and sample messages carriers expect, and set up opt-in and opt-out, so the campaign gets approved and your SMS gets delivered instead of filtered.
Yes. I rebuilt a Flex contact center with a custom plugin that shows each caller's history, Studio and Functions routing that captures every missed call, and TaskRouter rules that stop duplicate tasks.
Yes. Most of my Twilio work starts from a system that already runs: I review the code, the call and message flows and the account setup, fix what breaks first, and then extend it.
PHP (Laravel), Python and JavaScript, and n8n when the logic fits a workflow. The language follows your stack, not the other way around.
Every project gets a fixed quote once the scope is clear. The free 30-minute call is where we work out that scope, and you leave it knowing whether the project is worth doing.

Work already running in production

Twilio Flex · Contact center

An agency hired me to build the Twilio Flex contact center one of their clients was counting on.

The setup was a mess. Agents had no history on incoming calls, so they had no idea who they were talking to. Unanswered calls just vanished and nobody got called back. And the same contact would open three or four duplicate tasks at once. None of that scales, and the agency's client was feeling it.

I rebuilt it into a real omnichannel contact center inside Flex. Custom plugin so the agent sees every past call and message the second a new one lands. Smart routing through Studio and Functions: if nobody answers in 20 seconds, the call drops into an automated voicemail flow instead of disappearing. TaskRouter logic so one contact never opens more than one active task. Even a custom ringtone so agents don't miss calls when the browser tab isn't focused.

What changed:

  • ✓100% of missed calls captured (they used to just disappear)
  • ✓Conversations resolved 30 to 40% faster, with full context on screen
  • ✓Zero duplicate tasks, even in the bursty hours
"Gonzalo was truly exceptional. He went above and beyond to get things done. We boosted customer satisfaction by 45%." -- Jesse Fowler, CEO, OSC Web Design

Production · Law firm CRM

A Los Angeles law firm running its whole intake on tools that were never built to talk to each other.

They needed to handle heavy call volume and book appointments across multiple offices without things falling through the cracks. I built the platform from scratch and kept building it as the firm grew.

It started as call handling and scheduling and turned into a full CRM. Calls through Twilio, recordings pulled by OnSIP into AWS so managers can review them, appointments syncing both ways with Google Calendar and Outlook, real-time updates through Pusher, client files and multi-location scheduling in one place.

The part that matters: it holds up under 500 concurrent users and 20-plus background jobs running at once. This is not a prototype. It is production infrastructure a law firm has trusted and kept expanding for over a year.
