About this gig

Do you need an AI agent that actually gets work done, not just a chatbot that talks? I build custom AI agents using LangChain and LangGraph, connected to the OpenAI API. My agents can handle multi-step tasks, make decisions, and work with your existing data through database integration. What I offer: - AI agents that connect to your existing app or system - Multi-agent systems, where different agents work together on complex tasks - Database integration (PostgreSQL, MongoDB) so your agent can store and use real data - Clean, well-documented Python code, so you (or your team) can maintain it later My background: I'm an engineer working on AI-based systems for a technology innovation center, where I build AI logic engines, including virtual assistants and intelligent automation tools. I'm also currently building an AI-powered application for a real business client, using LangChain, LangGraph, and FastAPI. I take full ownership of every project, from understanding your goal to final delivery. Clear communication and honest timelines are part of how I work. Let's talk about your project before you order, so I can confirm the best package for what you need.

Hi, I'm Felipe, an Industrial Engineer from Colombia with a growing focus on AI automation and backend development. I build AI agent workflows and automations using n8n, LangChain, and the OpenAI API, and I develop backend systems with FastAPI and Node.js. I also create AI-powered chatbots and virtual assistants. Right now, I'm working on ZENDA, a web app for a bakery business, using React, FastAPI, LangChain, and LangGraph. I also design AI automation tools for internal reporting, using n8n and the OpenAI API connected to Google Drive.
