Gonzalo G.

I build production communication systems on Twilio: Flex contact centers, WhatsApp Business API, A2P 10DLC compliance, and AI voice agents. Recent work includes rebuilding a Twilio Flex agent experience with custom React plugins (call/message history on answer, Studio + Functions voicemail routing, TaskRouter fixes for duplicate tasks), A2P 10DLC campaign approvals, WhatsApp API integrations, and Twilio + ElevenLabs voice setups. Clients keep coming back for the same reason: the system works under real call and message volume. What I typically take on: • Twilio Flex — plugins, TaskRouter, Studio, Functions, agent desktop UX • SMS / WhatsApp — platforms, webhooks, real-time chat, automation • A2P 10DLC — registration, campaign approval, carrier troubleshooting • AI voice — Twilio Voice + LLM / ElevenLabs agents and handoffs Stack when the product needs it: PHP/Laravel, Vue/React, AWS, and clean API integrations. I’m a Twilio Champion with 100% Job Success on Upwork. I’m available part-time for focused side engagements. If you have a Flex, WhatsApp, A2P, or voice problem in production, send details and I’ll tell you quickly whether I’m the right fit.
