Nacho
González-Garilleti
Software engineer, 9 years in production. I build AI agents that are allowed to act on real systems.
Currently technical lead at OpenVPN, with 10 engineers across development, QA and DevOps, after leading a cross-functional team of 7 at Cognigy.
I like automating things, at work and at home.
"Success is not assured, failures either."
Open to staff, lead and founding-engineer roles: building AI agents in production, and the team around them. Permanent or contract.

Technical Lead Engineer
Sep 2021 — Oct 2025
Led AI Copilot and Live Agent with a cross-functional team of 7 reporting to me, turning live messages and call transcripts into real-time guidance for contact-centre agents. The products served Lufthansa at 13k+ conversations a day. I also owned the integrations that hand a conversation from the AI agent to human agents and back, with RingCentral Engage, Salesforce, Genesys and others.
Live Agent · Lufthansa
Scaled the bot-to-human handover from 50 simultaneous agents to 500 registered and 200+ active, at 13k+ conversations a day, through the peaks of Lufthansa's strikes.
AI Copilot
Sentiment analysis and real-time guidance for contact-centre agents, from live messages and call transcripts.
Real-time path
Moved websockets from broadcasting every event to all agents to per-subscription delivery, and added PostgreSQL read replicas with automatic failover on Kubernetes.
