Product Engineer — LLM agents in production · Go
I understand a business and turn it into an agent.
For three years, with sogenio.com — a platform I designed — I put around ten agents into production on WhatsApp and Instagram, in Latin America, for hotels, clinics and hair salons. I did all of it: understanding the client's business, imagining the agent, building it, shipping it to production and making it evolve.
What makes an agent hold up in production
- Its economics
Does it earn more than it costs? The question comes before the first line of code, and gets measured after.
- Its security
The harness is the first vulnerability. What the agent is allowed to do matters more than what it can say.
- Its tests
On a bench, with synthetic and real cases, before every change of model or prompt.
- Its observability
Score the agent's activity, don't just watch it. An agent you can't judge, you can't improve.
