I offer all types of testing services: usability, load, API, UI Automation, etc. I can also implement new features for your web application or fix bugs in it. Some of the tools of my trade: Python, Ruby, Javascript, Jenkins, REST APIs, Rails, Sinatra, Flask, bash, Java, Jenkins, Watir, Selenium, Puppet, Chef, Docker and more. I'm more than willing to learn on the job too. Furthermore, if I build a tool for you, I will document it and work with you so that you can maintain it going forward, if that is your goal.

I offer technical consulting as well, consider me a sounding board for any decisions related to development, testing, deployment and design.
