Johnny David Santana Segura

Johnny brings an unusual angle, a marketing background and an MSc in Innovation Management, paired with a genuine interest in ML and data. His seven repos form the most thematically coherent set in this group: hotel-cancellation prediction, a Kaggle MLB pitch-classification competition using neural nets, sales forecasting, and data-visualization notebooks, all in Jupyter. No stars or verified external contributions, and recent commit activity has lapsed. The work is self-directed coursework-and-competition rather than production ML, but the focus and applied-problem framing are a real, distinguishing signal for an early data practitioner.
