With an academic background in finance, actuarial science, and mathematics, he combines AI and behavioral economics, develops financial analyses related to Data Science projects, and builds business optimization models.
Delivering data warehouse and ETL solutions as part of an Agile team using advanced ML techniques to improve performance and processes.
Helping build and improve infrastructure, application, and performance development and ensuring tight security including data encryption, security groups, and environment scanning.
Ensuring high-quality deliverables and implementing DevOps and security best practices in fast-paced environments.
Worked remotely as the acting lead data scientist for a Series C startup based in San Francisco.
Created the core business optimization model for supply matching, which uses a similar architecture as Google's AlphaGo and was written in Python with C++ binding.
Maintained high code quality through code reviews, automated tests, and continuous integration.
Composed several reports and insights to improve supply matching using graph theory, statistic inference, and Machine Learning.
Led the churn-reduction program with an objective of a 20% reduction in churn across eight countries.
Oversaw the development of ML algorithms and management of external resources to design and implement the final architecture.
Created an ML algorithm to improve the company's mobile app by understanding client behavior to remind them of actions they might have forgotten to do.
Supervised the hiring, building, and leading of a team of three data scientists and led a team of five consultants based in Spain.
Developed a financial analysis to justify capital investment in Data Science projects.
Consulted with various clients on actuarial science and portfolio analyses.
Segmented a health insurance company portfolio to predict the financial impact of a new regulation and gave recommendations to clients as to what type of product to develop.
Led the yearly update for a product of Addactis PM Export and coordinated and tested the software development with the engineering team.
Gave talks about using Machine Learning to learn about client behavior.
Developed a web scraper for an online insurance business in Chile and created a model to react to changes in competitors' prices for each segment. The model combined game theory, behavioral economics, and Machine Learning to bring profitability to the car insurance industry, which is known for having an extremely low return on investment.
Built a supply matching algorithm for a startup using Python and C++ bindings. Using Monte Carlo Tree Search combined with a fast and slow neural network evaluator, the system determined the best possible move to improve overall COGS and reduce errors.
Created a recommender system for an Indian online video-sharing platform. The system made recommendations at the end of each video, based on context instead of pure similarity of content, with an API response time of 45 min.
