Daniel Connelly

Principal Engineer at Teads in Paris.

I previously spent close to ten years at Google, where I worked on Google Chrome (including enterprise features, password management, and autofill), Google Maps (including mobile app internals, full-stack feature development, a production ML system, data pipelines, and search), and the GCL configuration language (similar to Jsonnet). In two internships during my graduate studies I also worked on the GWT and J2ObjC source-to-source compilers.

I also worked at Butterfly Network on cloud-based real-time medical data and workflow integration systems (think HL7 and DICOM) and MIT Lincoln Laboratory on prototype service-oriented-architectures for DoD and FAA projects. I studied mathematics and computer science at Georgia Tech.

You can find me on GitHub, LinkedIn, or send me an email.
