What I'm looking for

I'm looking to apply Python, machine learning, GIS, and numerical simulation to scalable engineering applications in renewable energy, environmental risk, climate resilience, and infrastructure digitalization.

I am a Spatial Data Scientist and Computational Engineer specializing in Python automation, geospatial analytics, and numerical modeling. I bridge the gap between engineering domains, spatial analysis, and modern software workflows to deliver data-driven solutions.

Core Expertise & Technical Stack:

Programming & Automation: Python (Pandas, GeoPandas, NumPy, Rasterio, Scikit-Learn), SQL (PostgreSQL/PostGIS), Git/GitHub, Streamlit.
Geospatial & Remote Sensing: ArcGIS Pro, QGIS, Google Earth Engine (GEE), Vector/Raster Analysis, Spatial Statistics, & ETL Data Pipelines.
Simulation & Computational Modeling: Hydrological & Hydraulic Modeling (HEC-RAS, HEC-HMS), Numerical Methods, CFD (FLOW-3D, OpenFOAM), & Climate Risk Analysis (RCP 4.5/8.5).
Analytics & Dashboards: Power BI, Time-Series Analysis, Predictive Analytics, & Decision-Support Systems.
Experience Highlights: Developed automated Python data pipelines and simulation workflows supporting hydropower infrastructure, flood hazard assessments, and climate impact modeling. Proven track record in processing complex environmental time-series datasets and collaborating with cross-functional engineering teams.

Seeking remote roles in Spatial Data Science, GIS Engineering, Computational Modeling, and Python Data Analytics.
