Firefox

When I started working on AI at Mozilla two years ago, I was a Python developer with a background in web services and three months of machine learning experience from working on the Nuclia DB project. I was not someone who had trained models from scratch or built production ML infrastructure. Today, Firefox ships multiple AI features that run entirely on-device, and I helped build the infrastructure that makes that possible. This is a retrospective on what we accomplished and what I learned along the way.
