Diana Dupuis, VP of Engineering at Astonish Design, discovered her passion for computer science and web development by accident. Her son enrolled in a college physics course when he was unusually young and the professor asked her to accompany him to class. The following semester, she gave up writing and returned as a full-time physics major. After one (required) semester of C++, she dropped physics and followed the path of web application development (before there was such a thing).

Prior to her work at Astonish, Diana built features for big websites at Four Kitchens, including a custom credit card processing extension for the Wikimedia Foundation and modules for enterprise Drupal clients. As lead on the Economist project (Austin team), she and her teammates built a number of features including a dynamic, scalable topics aggregation system and an archivable homepage publishing tool. Later, she focused on team management and solution architecture as Director of Development and Professional Services.

Diana enjoys speaking, training and developing curriculum as her contribution to the open-source community. She has has been invited to speak at conferences and open-source events around the world. She especially enjoys working with beginners and encouraging women to try programming.
