• The IOI 1991 Cuba contestant and the HCA data scientist are the same person: he medaled at IOI in 1991 (high-school age) and began a BSc in Computer Science at Universidad Central de Las Villas that same year, so the IOI appearance is the documented start of the exact computing path his LinkedIn now continues - strongest identity link between the two records.Jan 1991
• Represented Cuba at IOI 1991 as a high-school contestant, winning bronze (rank 38 of 68) - the earliest firm public record of him and the origin of a 35-year computing career.Jan 1991
• Career arc runs from a Cuba BSc (Universidad Central de Las Villas, 1991-1996) through Orlando-area ML/software roles (Design Interactive, FAZ, Sonobi, SoarTech, Disney) to Paige (AI, 2021-2024) and now Lead Data Scientist at HCA Healthcare (2024-), a steady migration from R&D contracts into applied healthcare AI.2024
• PhD dissertation 'Batch and Online Implicit Weighted Gaussian Processes for Robust Novelty Detection' (UCF, 2015); his weighted-GP work is cited by later robust-GP literature, showing he contributed a research line before moving into industry.Jul 2015
• Education spans three countries (BSc in Cuba, a Pedagogy diploma in Guatemala, MSc+PhD at UCF in Florida), suggesting a period based in Guatemala before settling in the US.2007
