- Designed and implemented the investor and sales pitches.
Technical Program Manager
Google Research
- Brought the primary project from its concept documentation to the delivery of photorealistic 3D reconstruction for self-driving car AI training (Waymo) at the city scale.
- Technical implementation and design of an AI-powered texturing engine for the 3D reconstruction of buildings.
- Launched and operated 2D / 3D data creation pipelines for ML training, leading to multiple Maps improvements.
Lead Product Analyst, Geo Imagery Ops
Google Maps
- Implemented ML pilot projects for 5x time gain on bike lane mapping in new countries.
- Led the development and maintenance of a pool of 80+ dashboards and ETLs used by the management of a 500-people Ops organization.
- Redefined the resource allocation model for StreetView driving, leading to a 14% gain in driving efficiency in global operations.
- Organized collaboration with the City Council and university (UCD), leading to the integration of Google's emissions data in the city's climate action planning.
Data Science Fellow

- Created end-to-end NLP pipeline with Spark and Doc2Vec to detect sensitive content in movie subtitles and classify movies accordingly.
- Implemented with Frequentist and Bayesian frameworks for A/B Testing and applied to numerous use cases.
- Detected fraud in a large dataset of transaction data and built a monitoring dashboard using Flask / MongoDB / Matplotlib.
- Analyzed, visualized, and predicted churn likelihood in transportation data from a ride-sharing app using Gradient Boosted Trees, SVMs, Random Forests, and ensembling techniques.
- Built a recommendation engine based on joke-like data from the Jester dataset using matrix factorization and collaborative filtering techniques.
Data Science Consultant
Self-employed
- Detected fraud in car insurance claims by implementing random walks on bipartite graphs.
- Predicted the price of car parts leveraging recommender systems on car insurance audit data.
- Implemented web scraper to collect several million entries for a movies/actors/productions database.
Business Intelligence Manager
MONOQI
- Led the business intelligence department and its business analyst team for a 1 million-member startup.
- Ensured data quality and information access by building dashboards and data pipelines from various sources and designing the data warehouse. Used SQL, AWS S3/Redshift/DP, and Ruby on Rails.
