I am a strong believer in test automation and in adapting to the environment and circumstances. My main focus as a developer and quality assurance engineer is on code quality through automated tests, development tools (possibly developed in-house, like RoboHydra), documentation, workshops, ready-to-use packages and reusable libraries. I have years of experience designing and writing web applications but have also built some cross-platform GUI-based applications (using Qt, WxWidgets and Tk). I am also very experienced in customisation and maintenance of Free Software: I was a Debian Developer between 2002-2011; was one of the lead developers for mEDUXa, a Linux distribution for Canarian schools; and have maintained a number of free software projects throughout the years.
Senior Software Developer.
Worked on both frontend (ES6, React, Redux) and backend (Python, Flask, PostgreSQL). One of the main maintainers of an external API for customers. Helped define rules for better APIs. Basic usage of fabric and Docker.
Developer in the Analytics team, member of the API and QA guilds.
Rewrote the notification server in Node.js for maintainability reasons, used Ansible and Jenkins to improve its deployment, and added statistics, graphs, and alerts, using Zabbix and Kibana, to gain an overview of the system health.
Worked in the mobile team, designing and implementing APIs to be consumed by the mobile applications.
Helped getting several teams started with RoboHydra and API testing.
Gave several RoboHydra talks, and Clojure talks and workshops.
Quality Assurance Engineer, Project Manager and Developer. Lead QA for several projects, including Opera Link and My Opera. Project Manager for Opera Link, Dev Opera and My Opera. Developer for Opera Sync (new version of Opera Link) and other projects.
Software packaging, development of internal tools, automated testing, testing infrastructure and coordination, specs, guidelines and documentation.
Built a testing environment and automated testsuite for the Opera Link server and for My Opera.
Built several mock servers to improve the reliability of some functional tests, and to dramatically improve the testing of the Opera Link clients. This work was the seed for the ideas in RoboHydra.
Helped design, document and test the Opera Link API. Wrote two articles (now offline) about the Link API on Dev Opera.
Wrote several automation tools (a database migration tool called Migraine, among others) and improved processes in different projects.
Setup and maintenance of a Continuous Integration Server.
Gave many talks and workshops on tools, processes and software automated testing. Organised several lightning talk sessions.
Built a Debian package repository with packaging guidelines and documentation, along with many Debian packages for both internal and external software. Part of this work was designing, implementing and releasing Arepa (Apt REPository Assistant).

1 Oct 1995 - 10 Oct 2000
Programming, Software Engineering
"RTHC: Un conversor de RTF a HTML" ("RTHC: An RTF to HTML converter") was given the highest degree ("Matrícula de Honor", A+).
Design and implementation of a generic RTF parsing library in C++, using Design Patterns and UML for the design and the STL for the implementation.
Design and implementation of an RTF to HTML converter utility, using the above library for parsing, and gettext for i18n. The conversion utility was translated into several languages.
Study and documentation of the RTF format.
Study of the Free Software Community history, resources and way of work.
Packaging of the above software for RPM- and Debian-based systems.
A talk describing all of this was presented at Hispalinux III.
