I have been working on software automation since 2006, when I had my first IT job. Moved by my passion for hacking and code, I learned a lot of cool stuff and now I consider myself a self created software hacker.
My current experience and passion is mostly:
Manual Software Testing: Automation is what I love the most, but manual testing is a must for me in order to learn about testing processes and techniques.
Software Automation: I have been working with this since 2009, but I still consider myself a padawan. I worked mostly with Selenium/Webdriver, Sikuli, Autoit and QTP, but I also have a lot of friends that help on my work, like TestNG and JUnit, Jenkins and even Cheff.
Test Framework creation: I created many testing frameworks for different purposes, most of them based in Java and Webdriver, but also using Ruby and Sikuli.
Stress testing: I mostly did stress testing for phone boxes over complex network simulations, but I also hacked around with web apps stress and performance testing.
Simulations: For many of my tasks I needed to simulate complex situations, like having 1000 people making inbound calls to a call center, having unstable network connections (simulated by me) and growing database sizes and load, reporting everything in real time.
Coding: I love to code, I consider the internet the best friend for my curiosity, I currently spend most of my free time programing in Java, Ruby and sometimes in Scala.
Team management: I am currently in charge of a successful project with 10 automators.
Teaching: I have been teaching software automation for students in Montevideo, Uruguay, La Plata, Argentina and Chicago, USA.
Interviewing: I like to interview people, I think I learn a lot from them, and I also help my own company to work with the best people. I also see this as a big responsibility, so if I work with the wrong person, is also my fault ;)
