Notes from buildingwith data and AI.
I'm Oswaldo Orona. I write about the systems I build, from retrieval and AI agents to the data work underneath. Read the decisions, explore the results, and inspect the code.

About
I'm Oswaldo Orona, a Principal Database Administrator and AI practitioner based in Denver, CO. I hold an MCS-DS from UIUC (Tau Beta Pi, Phi Kappa Phi) and bring 25+ years of database experience alongside deep hands-on work in machine learning and AI engineering.
My focus areas include Retrieval-Augmented Generation (RAG), AI agents, Model Context Protocol (MCP), geospatial AI, and financial AI, all running in a self-hosted Proxmox home lab with Docker and LXC.
This blog is where I document explorations in latent space: the ideas, experiments, and systems that live between the data and the model.
