Ian Stapleton Cordasco

I am a Senior Software Developer with over 6 years of experience working on Open Source Software and 4 years of professional experience. I am a core developer of several widely used Open Source Python projects and a core reviewer of several OpenStack projects. I practice Agile Software Development both at work and in my free time. I provide experienced architectural feedback on software and systems design.

I love building software for developers that helps them be more productive and happy. I am passionate about making software secure by default and easy to use. I strive to be a good mentor and constantly improve. I thrive working on complex challenges, especially when I can find a solution that has other benefits.
