Project history
Conducting professional training in Advanced Data Analysis and Power BI, focusing on teaching analytics, visualisation, data driven decision making and data storytelling.
Applied Data Science and AI methods to optimize industrial processes and conduct the digital transformation of the refinery, as part of the Digital & Operational Excellence team. Managed and participated in strategic projects with cross-functional stakeholders. Implemented a refinery digital twin (Refinery Advanced Scheduling) using object-oriented Python, SQL, React, and Docker, simulating 100+ weekly scenarios to optimize outcomes, cutting planning time by 50% and reducing operating costs by up to 5%. Collaborated with Boston Consulting Group (BCG) in an Agile/Scrum environment.
Developed interpretable logistic regression models to predict mortality in ICU patients with pneumonia, achieving 0.86 balanced accuracy. Wrote and presented an article at the CIARP 2023 conference (26th Iberoamerican Congress on Pattern Recognition).
