Projects

SNCF DelayFlow — TGV Delay Analytics Pipeline

End-to-end ETL pipeline processing TGV punctuality data (SNCF Open Data) with PySpark. Includes distributed data transformation with Spark SQL, structured Parquet storage, a Random Forest predictive model (Scikit-learn) for average delay forecasting, and an interactive Streamlit dashboard diagnosing root causes across infrastructure, traffic, and rolling stock dimensions.

Open Source Contributions

  • PMD

    3 merged PRs fixing false positives in static analysis rules — one in Apex (FieldDeclarationsShouldBeAtStart not recognizing property accessor syntax) and two in Java (UnusedLocalVariable false positive for pattern variables in braceless for-each, and a parser failure on switch expressions inside super() calls). Released in PMD 7.20.0 and 7.21.0.

  • Checkstyle

    2 PRs under active review: a bug fix for a false positive in IndentationCheck triggered by new operator expressions (#18686), and an enhancement to surface the expected line separator in NewlineAtEndOfFileCheck violation messages (#18972).

  • Talawa API

    3 merged PRs achieving 100% code coverage on mutation resolvers (unit and integration tests).

  • WeasyPrint

    Contributed bug fixes and improvements to the Python HTML/CSS-to-PDF engine and interacted with core maintainers during the review process.
