I like Software! Specially Free/Libre/Open Source Software. That’s why I’d like to define myself as a FLOSS generalist. My main develpment environment is Linux, naturally, but I can use Windows as well. I’ve played different roles in the past: frontend, Backend, Sysadmin and DBA. Some of the tools I have used recently are:
- Databases: MySQL, PostgreSQL, SQLite
- OS: Linux, Bash
Ecommerce for Holokinesis Libros, a small publishing company.
This is my main personal project. I work on it on my free time. We started around March 2010 with a Plone 4.x site, which included a custom theme with some custom content types using Dexterity and Products.PloneGetPaid, which was still alive then. After several shortcommings with Plone, we migrated to Django and DjangoLFS and created some plugins to make it work for us. Now DjangoLFS is showing its age and we are already working on migrating the site from django to Woocommerce.
A collection of experiments, old and new
Every now and then I want to test some library or concept or I just need a small tool to scratch my itch. This is where I upload them. Feel free to walk around.
During my time on Purism I worked integrating Wordpress and Woocommerce with our middleware runnning Django. Other small tasks and technologies included LDAP, Jekyll, Gitlab CI, PHPUnit, Python Virtualenv/Pipenv, Bash, Docker and Vagrant.

Enable DEVSIM to simulate solar cells
May - August, 2018
DEVSIM is a TCAD (Technology Computer Aided Design) semiconductor device simulation software. TCAD tools are special simulation software that can simulate the fabrication process of semiconductors as well as their operation. The objective of this work is to add the necessary improvements to DEVSIM so it can simulate solar cells.
SRAX Web Developer
November 2015 - August 2017
Around that time, the company’s Ad exchange backend was the typical LAMP stack with a lot of legacy code on stored procedures and PHP/CodeIgniter code. Bootstrap and vanilla JS were used on the frontend. At the end of my time on Social Reality we had integrated several ad exchanges into our backend (a big change) Besides the developer role, I also enjoyed administering the Linux servers. We used Puppet to manage the systems configuration.
Valutech Outsourcing S.A. de C.V. (now Clover Wireless)
October 2013 - November 2015
My main responsibilities included administration, maintenance, backup and optimization and emergency response for SQL Server databases, IIS, and Linux hosts for ftp, web and backup systems, all integrated into the company’s Active Directory server. I had a very good time working for Valutech’s IT team because they managed their own data center; we had the chance to tinker around diferent virtualization strategies like VMWare, Azure, Amazon Web Services like EBS, EC2 and S3, and VirtualBox for local testing. The main database server required High Availability configurations, but beside the high concurrency load, we also had to be really watchful for all the developers ensuring they don’t run naive queries that otherwise would trash the DB server. Also since database sizes typically exceeded Terabytes, we had to be a bit extra careful for backups.

Data acquisition engineer.
May 2006 - December 2008
As a Data Acquisition Engineer I was in charge of the commissioning and operation of DA hardware and software. I became the in-house specialist for pressure, temperature, voltage, current and vibration measurements as well as video over IP and networking. I was also in charge of assuring that our instruments were always calibrated with traceability to the NIST and always ready for use, that included dealing with purchasing and supply chain departments. I successfully concluded my Six Sigma Green Belt course. Software tools included: Windows, Linux/Apache/MySQL/PHP, Python, GStreamer. DA equipment included brands like Scanivalve, Dewetron and Genesys (LDS Test and Measurement).

Kalman filter simulator as internship project. Tools used included Matlab, C, Assembler and Atmel microcontrollers.
M.Eng. UABC, Instituo de Ingeniería
Thesis title: ESTUDIO POR SIMULACIÓN DE LOS EFECTOS DE DISEÑO EN CELDAS SOLARES SEMICONDUCTORAS. I used Silvaco’s TCAD software simulate the fabrication solar cells using Crystaline Silicon as substrate with Boron and Phosphorus as dopants using diffusion or ion implantation. I used this knowledge to work on 2018 edition of Google’s Summer of Code.
