Projects

A conversational agent for e-commerce built with Ollama, LangChain, and ChromaDB, comparing three open-source LLMs — Qwen3 4B, Llama 3.2 3B, and Phi-4-mini — for product search, order tracking, recommendations, and RAG-powered FAQ. Benchmarks tool-calling accuracy, multi-intent handling, and response time across all three models.

Agent-based simulation of the iterated Prisoner’s Dilemma on adaptive networks. Explores how cooperation emerges through imitation (Fermi Rule), dynamic rewiring, and Pareto wealth across Erdős-Rényi and Barabási-Albert topologies.

This is a practical introductory course created for the Digital Technology course at the Universidad Nacional de Colombia, highlighting the potential of Single Board Computers (SBC) such as the Raspberry Pi, where the true power of these devices is achieved through the coding process, which unlocks their full capabilities.

‘Gabo’ is a RAG (Retrieval-Augmented Generation) system designed to enhance the capabilities of LLMs (Large Language Models) such as ‘DeepSeek-R1’, ‘Llama 3.2’, and ‘Phi 3.5’. This project honors Colombian author Gabriel García Márquez by marking the tenth anniversary of his death.

A Python project that explores the dynamics of cooperation and competition through the lens of game theory. Employing cellular automata and classic tactics like Tit For Tat, the project investigates the performance of various strategies in the context of the Prisoner’s Dilemma.
