PROFILE

Sylvain Brunato

Sylvain Brunato developed and maintained backend systems for the CS-SI/stac-fastapi-eodag and CS-SI/eodag repositories, focusing on API reliability, automated release workflows, and data model validation. He upgraded Python dependencies, integrated Ruff for code formatting, and optimized pytest-based test suites to improve performance and reduce regression risk. Sylvain consolidated development branches using Git, streamlined CI/CD pipelines with Docker and GitHub Actions, and introduced a PyPI publish toggle for deterministic artifact management. He also created the stac-pydantic package for conda-forge, enabling STAC-compliant data validation with Pydantic models. His work demonstrated depth in Python, CI/CD, and data modeling.
