Mercado Libre is one of the largest eCommerce platforms in Latin America. I was part of the team who developed the recommendation system. This included recommending alternative and replacement items for the one that users are currently viewing.

It evolved developing a machine learning model that can predict which are the best items to show, creating metrics and dashboards to display the success, and developing a simple yet powerful API that can serve its results very fast.

Tribute is a site for creating video homages for a friend or family member. It provides a way to upload and edit individual videos and produce the final result right on the web.

I was a full stack developer and main developer for years on this complex web app that combined front end video editing and back-end video rendering.

For the front-end, we used a combination of Ember and React and for the back-end, we used Python with Django and djangorestframework. We deployed using Heroku and had a dedicated pipeline for rendering the final videos and delivering them to the client.

We connected with different APIs for things like advertisements, analytics, product delivery, and customer support.

I worked as part of the Python distribution Anaconda on the repository team which was the back-end for the conda package manager.

I had to develop the API for external and internal use of the Anaconda ecosystem and dealt with delivering binary packages and metadata for the clients to consume.

The API was built using Python and Flask and was deployed using Docker instances.
