Experience

Mostaza App

http://www.mostazaweb.com.ar/

A web and mobile application for the largest fast-food chain in Argentina.

I worked on the project as the back-end developer and developed the necessary endpoints for the deployment of the platform. I primarily worked on the mobile application (Android and iOS), since it was the main means of interaction with branches.

Some of the implemented features:
• Login with social networks
• Push notifications
• Admin dashboard to manage application settings and company products

pyTopoJSON

https://github.com/fferrin/pytopojson

An extension to GeoJSON that encodes topology, implemented from scratch in Python.

GeoJSON is a format for encoding a variety of geographic data structures. TopoJSON is a format that allows you to, among other things, eliminate redundancy, reduce the file size by using quantized delta-encoding for integer coordinates, and simplify geometries while preserving topology.

Winner of Hackathon

My team and I won a hackathon where the main goal was to generate and implement ideas that offered insights based on videos from a mall. For this, we apply several neural networks in order to detect and track customers inside the building and recommend them with different products depending on what they were wearing and the places they visited.
