Road Weather App for Connected Vehicles

A data app for an on-the-road, real-time weather forecast powered by machine learning.

I was the lead data scientist and was in charge of labeling the raw geolocalized time-series data and training a model. I worked with the data engineer to integrate the model into Kafka Streams architectures and helped the second data scientist develop, in Python Bokeh, the front end to display the predictions in the driver dashboard.

Data Exchange Platform for Agriculture

An open-data exchange platform for agriculture actors.

I was the product owner and liaised with the stakeholders and the development teams to deliver the first version of the end-to-end backbone of the target data platform in under three months.

A Comprehensive Data Platform for Archaeologists

As a data team of one, I designed and developed a comprehensive data platform for archaeologists. It utilized Esri and Dropbox as the data source layer, n8n workflows and custom Python scripts for the data ingestion layer, MinIO and PostgreSQL for the data storage layer, Dagster for the data orchestration layer, dbt for the data transformation layer, and Metabase as the data visualization layer. In addition, I implemented the Hugging Face framework for building and deploying machine learning models to provide advanced data analysis capabilities. Finally, it leverages GitOps as the operational framework to automate code management and deployment, increasing efficiency and productivity.

Archaeologists have widely adopted the platform, saving significant time and resources in data management and analysis.
