Portfolio

Real-time Pricing Strategy
Real-time Pricing Strategy

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.

Supply Matching Algorithm
Supply Matching Algorithm

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.

Recommender System
Recommender System

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.
