Project History
New Data Platform for Dashlane
http://www.dashlane.comAs Senior Data-Engineer in a five people data engineering team, I designed and built a modern data platform, replacing the legacy one.
The new data platform is based on AWS serverless services, and modern technologies like Airflow, DBT, and Airbyte.
The new platform acquires over 100 million events and 1TB of data daily.
It comes with Continuous Deployment (Terraform and Gitlab CI), real-time monitoring and alerting (Cloudwatch and Slack), and low operational costs (pay-per-use pricing of serverless services).

Real-time Data Pipeline to Compute Tolling for Millions of Vehicles
At Continental, we built a tolling solution in charge of collecting locations from millions of vehicles and computing tolling charges based on geographic pricing rules.
I designed and contributed to the development of the main pipeline in charge of the tolling. It is based on Kafka, Spark Streaming, Spark SQL, Go microservices, PostgreSQL, and S3. We managed to build a fault-tolerant and horizontally scalable pipeline. To achieve a high level of quality, we had made a significant effort on the CI/CD, including all infra-as-code, automatic unit tests, and continuous integration tests.

Data Acquisition for Airbus Data Platform (Skywise)
I contributed to the early stages of the construction of Airbus' main Data platform. As technical leader of the data acquisition team, I built a solution that enabled our team to configure and deploy new data acquisition pipelines in a single day.
We handled various data sources (ERP, Aircraft, partners, HR, Finance, production plants, etc.) and ingested over 5TB of data daily.
