Developed models for sizing of the sales agent workforce in order to reach monthly sales and margin goals. Developed a forecasting system for sales KPIs with models under 20% error, together with reports and notifications. Analyzed the patterns of returning customers and implemented a model to predict the time of return for appropriate timing of calling.

Bogotá D.C., Colombia

Engaged with customers to understand their business objectives, analyze their data and translate said objectives to Data Science requirements and projects. Also developed these data products, for EDA visualization and dashboards with Dplyr, Pandas, ggplot, Altair and PowerBI and for machine learning models using R, Caret, mlr, Python, Scikit-learn.

Bogotá D.C., Colombia

Designed and implemented a web application using Python/Django and agile methodologies to help sales representatives keep track of clients and goals. At the same time the application was designed to help Executives track performance of their representative’s performance and associated costs. For the latter, we designed several metrics and created.

Boulder, CO

Under supervision of Ana M. Rey, we studied the theory of entanglement measures such as Spin Squeezing, Quantum Fisher Information and Entanglement entropy in the all to all Ising Model, with calculations and simulations performed in Wolfram Mathematica. We conducted this research with the objective of finding new benchmarks for the current experiments.

Bogotá D.C., Colombia

Developed new course material for courses in computer infrastructure, in particular labs, for topics in low level software concurrency, performance and security. In addition, I lectured the lab sections and assisted students with all doubts regarding the course, and guided their project developments.

São Paulo Y Alrededores, Brasil

I researched differential geometry and theory of group representation in curved spaces, mainly working with the De Sitter space to visualize and understand its properties that could bolster the use of this alternate space for new cosmological models.
