Acerca de este Servicio

Need a custom AI agent that calls your APIs and databases, not a ChatGPT wrapper?


I build Python AI agents with tool calling. The model selects the tool and arguments. The backend executes them with guardrails: parameterized queries, no free-form shell, typed inputs. You get a FastAPI service, optional web chat, and your LLM (OpenAI, Gemini, Groq, or another provider). You keep the keys.


I work as a Senior Technical Support Engineer on digital platforms (APIs, QA, incidents). I build agents a support team can run, not a demo that breaks on day two.


What you get:

- Intent router and specialized agents (1, 3, or 5 by package)

- Typed tools for APIs, databases, search, or reports

- Source code, README, and a short demo

- UI copy in English or Spanish


Message me before you order with: the job the agent must do, data sources, and which LLM. I will confirm the package. I do not copy confidential client systems; every build is scoped to your stack.

I am a Senior Technical Support Engineer for digital platforms (Whale Cloud) with an IT/BSS project management background (WOM Chile). I handle REST API integrations, Postman QA, incident RCA, and transactional monitoring. I also build the tools support teams use on shift: Python/FastAPI AI agents with tool calling, natural-language database assistants, and OpenSearch log/tracing consoles. The model never writes raw SQL or shell — it selects a closed tool; the backend executes with guardrails. English and Spanish. Tell me the operational problem. I will tell you if I can ship it.
