From Quiniela to Machine Learning: Building a World Cup Prediction Demo with Oracle Machine Learning

Introduction Some demos are born from a very technical requirement. Others are born from a simple idea that everyone immediately understands. This one started with a familiar concept: a football quiniela. The objective was to prepare an engaging demo for an event where business users, technical teams, and customers could easily connect with the story.

Oracle, Explained Like a Curious Case Study: History, Strategy, and the “Layers” of a Tech Giant

Disclaimer  I work at Oracle. This article is not official Oracle communication and does not represent the company’s views. It’s my personal attempt to understand Oracle as a case study. Recently, I watched a video about Oracle’s history and realized I didn’t actually have a calm, structured mental model of the company. I knew the

From Zero to a Working YOLO Classifier on Oracle Cloud: Training an Insect Model End-to-End with OCI Data Science + Object Storage + Gradio

There’s a very practical question behind many AI conversations with customers: “Do we actually have the infrastructure to run and iterate on computer vision models reliably?” This project started as a hands-on way to answer that question with a concrete artifact:a working YOLO-based image classification model, trained on a real dataset, packaged with a Gradio

How to Add a Floating GenAI Chatbot to Oracle APEX (OCI Generative AI / Cohere) — Step by Step FULL CODE

In the past weeks I’ve been working on an Oncology Forecasting prototype built with Oracle APEX + Autonomous Database (ADB). The goal is straightforward (but very powerful): let business users define a scenario (country, indication, time horizon, epidemiology assumptions, products…), run the forecast, and then explore the results. The real challenge is not only computing

2025 Was a Reminder That Markets Don’t Move in Straight Lines

A rigorous recap from a curious amateur — and what the evidence suggests we should watch in 2026 (not financial advice). I’m not a finance professional. I’m simply someone who’s curious about how the world works — and who learns best by turning headlines into a structured, source-backed narrative. After watching a Spanish video that
