My roles and responsibility

  • Fine-tuned a pre-trained Vision Transformer (ViT) using PyTorch on satellite imagery datasets, improving model generalization and inference performance for land use and geospatial analysis across multiple terrain categories.
  • Built automated data preprocessing and feature engineering pipelines using Python to optimize geospatial and agricultural datasets for LightGBM model training, reducing data preparation time by 30% and improving overall model reliability.
  • Designed a PostgreSQL database schema with PostGIS extensions to store and query geospatial datasets, structuring satellite imagery metadata and land classification outputs for efficient retrieval by research teams.
  • Deployed trained models as REST APIs using FastAPI to serve real-time land classification and yield predictions, reducing average query response time to under 200ms for internal analysis tools.
  • Created an interactive Streamlit dashboard integrated with ElasticSearch-indexed survey reports, allowing analysts to visualize model outputs alongside historical land-use records and cutting manual document lookup time by 50%.
