Work Experience
Developer Helicon Jan 2015 – Jul 2015
 Worked as a developer in Helicon, a rising company here on Monterrey that currently holds a couple of national impact projects as script
designer, app designer, database manager, data scientist, system architect, and requirements engineer.
 Most of my work has been in several areas, worked with a political party in 2 elections, building all their system for election progress tracking
(can’t really go into depth here), designed, implemented and tested a library for translating plaintext, binary, and base32 numbers.
 Installed an Nginx server with ELK stack (Elasticsearch, Logstache, Kibana), optimized it so it can manage around 500k simultaneous users.
 Implemented R statistical information that was used in the progress analysis, did some prediction analysis, also a graphical interface on R.
 Designed and implemented and application for PGR (State Justice Department, for its letters in Spanish). A system for automatically
managing chains of custody on different evidence types. Huge project in which I was in charge. Also helped their investigations dept.
Lead Designer, developer Geometrica May 2013 – Jan 2014
 Designed from scratch a web application to manage the workers' shift and owed pay with the Ruby on Rails architecture based on a
PostgreSQL database on the Monterrey construction plant (largest dome-building company on Mexico).
 Reduced consumed time per week for each of the area's bosses from 2 days sorting through punch cards to an hour on a web application with
complete access to the records and reports for 1 year prior.
 Unified the interface for monitoring reports and progress on different construction projects.
 Aided human resources on standardizing the bosses' reports and eliminated their need to generate graphs (app generated them automatically).
Projects
 OpenCV (2016) Open source library for computer vision with over 9 million downloads, working on several pull requests, as of writing
working in the machine learning module on a new feature for random trees classifier ( https://github.com/opencv/opencv ).
 Certex (2016) System for online notary based on BlockChain networks, public key encryption, and hashing functions (SHA256).
 Gestalk (2015) An application that used the Leap Motion sensor to identify your hands' position and using a neural network algorithm (I implemented it) to
translate it to natural language.
 State campaign (2015-2016) More can be discussed upon further questioning, as it is sensitive information I'm not at liberty to discuss much about it.
 Galileopack (2015) Designed and developed the python scripts for communicating automatic alerts in case of any health issues for running on a backpack
with sensors (intended for lone hikers).
 ML Projects (2015) Developed several machine learning methods using Java as part of my summer in Russia. This included an artificial neural network to
identify written digits, a classifier to predict house prices using several features, and several other data analyzing and interpretation works.
 PMC (2016) Started work on a personal server for streaming my media anywhere, using UPnP for universal connections.

Data Science specialization (September 2015 – current)
Currently interested on machine learning, looking to
specialize in the area so any work on the subject
would be met with motivation and devotion however,
any work I undertake I will pursue with passion and
expertise from working 4 years on the fields of web
development, database management, penetration
testing, and server administrator.
