Sofía · Collections voice agent
- Problem
- A lender can contact a late customer only in legal hours, once a day, on one channel a week. Every contact has to count.
- What I built
- Voice agents for two lending brands from one template. The integration decides identity, amounts and compliance; the model only talks. A console for the collections team shows every call's audit trail.
- Result
- Both agents pass the same 22-test battery; payment links go out during the call.
- Stack
- ElevenLabs Agents, FastAPI, Postgres, React

Social · Fundación Código Abierto
Building the door I didn't have.
Colombia's Caribbean coast holds about a fifth of the country's people and a tiny share of its startup capital.
