• In 2018, I led a complete redesign of the Criteo recommendation engine using representation learning, at the scale of billions of users and millions of items. We tripled the sales uplift of the product and delivered multiple million dollars in incremental revenue for the company. Read the blog post and arxiv paper.
• In 2006-2007, I was a core member of the MIT DARPA Challenge Team. We developed one of the first self-driving cars in the world and reached fourth place in Finale (only six teams out of 30 made it to the Finale). We published our design at IJFR'08.
• In 2005-2010, during my PhD years, I built end-to-end, real-time vision-based systems for navigation assistants under the supervision of Prof. Seth Teller. This work was published at CVPR'07, ICCV'09 and ICRA'10.
• In 2002, as an MIT intern, I parallelized a pipeline for large-scale 3D city reconstruction, written in C++ (The City Scanning Project, an ancestor of Google Maps). Using MPI, I reached a 15x speedup on a heterogeneous cluster of Silicon Graphics machines. This was my first project out of school! Here is the technical report.
