Experience

Developer with a primary focus on server side code and operations tools, who takes pride in writing clean, easy-to-read, well documented code. I endeavor to build tools to provide services to other developers so that they can focus on their own projects with confidence. I am also a developer who knows when not to write code and to adopt existing solutions to avoid endlessly reinventing the wheel.
