About me

Hi. I lead pre-sales at GitHub as the VP of Field Services. This diversely skilled department includes Inside and Field Sales Engineering and the Field Architecture teams. It's a privilege to apply my passion for open source, experience in enterprise software development, and ideas for the future of distributed collaboration alongside my amazingly talented colleagues.
