Hydraulic Engineer · Paris, France
Hydraulic engineer with experience in fluvial modelling, urban hydrology, and data engineering. I build Python tools that automate data pipelines and spatial analysis, turning raw hydrometeorological data into actionable flood risk intelligence.
Career
Nov 2024 — Dec 2025
Hydrologist / Modelling Engineer
WAK Group
Built Python pipelines for hydrometeorological time series processing, reducing manual work by ~60%. Supported hydrological model calibration (NSE, KGE), produced hydraulic hazard maps in QGIS, and created technical reports and dashboards for flood risk communication.
Mar — Aug 2024
Hydrologist — MSc Research Intern
CEREMA Île-de-France · Trappes
Reconstructed sub-hourly rainfall–runoff time series from Paris IDF curves. Developed and calibrated GR4H conceptual models for urban flood analysis. Authored MSc thesis on urban flood risk modelling methodology.
Nov 2020 — Jun 2022
Hydraulic Engineer
ASM Corporation Limited · Dhaka, Bangladesh
Conducted hydraulic studies for infrastructure projects: flow calculations, network diagnostics, culvert/canal/retention basin sizing. Contributed to flood and drainage risk management assessments for municipal clients.
Portfolio
End-to-end hydrology and hydraulics projects — from raw data through GIS analysis, modelling, and professional map production.
Statistical analysis of long-term rainfall records for Île-de-France. IDF curve development with Gumbel/GEV fitting, design storm generation, and climate trend detection.
