Badre Alloul

Geospatial Data Scientist & Computational Hydrologist

I ship production geospatial systems: flood-risk models, climate data pipelines, and energy-infrastructure tools deployed across Europe, North Africa, and MENA. Python-first, HPC-ready, GIS-native.

Background

About Me

Hydraulic engineer by training, geospatial engineer by practice.

I build end-to-end spatial workflows: ingest satellite data, run hydrological models, store in PostGIS/BigQuery, and serve via APIs or dashboards. I keep pipelines reproducible, tested, and documented.

Experience across research (INRAe), energy (ENGIE/CNR), catastrophe risk (REOR20), and public infrastructure (ANBT) keeps the work grounded in real constraints and operational delivery.

Apr 2025 – Sep 2025

Geospatial Software Engineer

INRAe — French National Research Institute for Agriculture, Food and Environment

Lyon, France

Productionized flood-damage research prototypes into tested Python packages while deploying Dask/xarray workflows on SLURM clusters for TB-scale satellite processing (Sentinel-2, ERA5-Land). Built PyQGIS plugins for vegetation indices and land-cover segmentation models (U-Net/DeepLabv3+) on multi-GPU infrastructure.

Nov 2023 – Apr 2025

Computational Hydrologist

REOR20 AG — Catastrophe Risk Modeling

Zurich, Switzerland

Built production 2D flood-risk pipelines and a serverless hazard platform on AWS, architecting an S3/STAC/COG data lake for climate data. Deployed FastAPI REST APIs on PostGIS hazard layers and automated country-scale DEM processing (GDAL/SAGA) into analysis-ready COGs for exposure modeling.

Mar 2021 – Oct 2023

Energy Systems & Data Engineer

ENGIE — Compagnie Nationale du Rhône — Hydropower & Renewable Energy

Lyon, France

Developed geospatial data systems for hydropower operations and renewable energy planning. Built cloud reporting pipelines (S3/Lambda) for regulatory indicators, fused SCADA with ERA5 for production forecasting, and created PV/wind site-suitability models (GeoPandas + MCDA) prioritizing 5,000+ grid-aligned opportunities using OnSSET least-cost electrification.

Oct 2019 – Aug 2020

GIS & Spatial Database Engineer

ANBT — National Agency for Dams and Water Transfers

Algiers, Algeria

Built geospatial infrastructure for national water-resource planning and dam siting. Designed a PostgreSQL/PostGIS database for 150+ dams with sub-500ms spatial queries, automated IDF curve derivation for ungauged basins, and developed a PyQGIS plugin for DEM analysis and watershed delineation used by field teams.
