Jeffrey Biles is a seasoned software leader and educator with 14 years of experience building full-stack products and developer-focused learning platforms. As CTO and cofounder of PhysicsGraph and longtime founder of Happy Programmer LLC, he blends product leadership with hands-on engineering across front-end and back-end stacks. His work spans rapid growth engineering and data pipelines—driving 6x organic traffic gains and measurable conversion improvements—alongside deep investments in teaching through EmberScreencasts, EmberSchool, and other tutorial projects. Trained in chemical physics with research experience in molecular biophysics, he brings a scientific mindset to designing mastery-based learning for the physical sciences. Based in Austin, he is as comfortable refactoring complex backend systems and shipping App Extensions as he is explaining difficult concepts to learners who have given up.
