I am a Ph.D. student and AI researcher with a strong focus on deep learning, computational neuroscience, and Large Language Models (LLMs). Working daily in a high-paced research lab, I specialize in transforming raw data into reproducible, high-performing machine learning pipelines. Whether it's fine-tuning LLMs for specific downstream tasks or building complex computer vision models, I bring rigorous academic standards and engineering best practices to every project. Core Tech Stack & Skills: Deep Learning Frameworks: PyTorch (Primary), TensorFlow, Keras. LLMs & NLP: Model fine-tuning (LoRA, PEFT, Hugging Face transformers), sequence classification, and prompt optimization. Computer Vision & Medical AI: 3D/2D CNNs, Vision Transformers (ViTs), U-Net architectures, and neuroimaging (MRI) analysis using MONAI, SimpleITK, and nibabel. Data Science & MLOps: Python, Pandas, NumPy, Scikit-learn. Experiment tracking (W&B, TensorBoard), version control (Git), and environment management (Docker, Conda, Linux)

I help businesses transform geospatial data into actionable insights through GIS, spatial analysis, interactive mapping, and Python automation. My work includes: • Parcel and land analysis • Spatial relationship modeling • Drive-time / accessibility analysis • Interactive maps and dashboards • GIS workflow automation • Large-scale geospatial data processing Recently, I developed a GIS automation tool for large-scale parcel and road relationship analysis in Australia. The system supports identifying frontage roads, parcel orientation, corner lots, and multi-road adjacency through rule-based spatial analysis workflows. The solution was designed for practical use in real workflows, and packaged as a standalone application with batch processing and configurable parameters for non-technical users. Core expertise: * Spatial analysis and GIS data processing * Map-based analysis and parcel-level studies * Road-network and accessibility analysis * Python-based geospatial automation * Data preparation for mapping and reporting workflows Tools & technologies: Python, GeoPandas, QGIS, ArcGIS Pro, PostGIS, Pandas, Shapely, Jupyter Notebook I also have experience building more advanced spatial rule-based systems that bridge traditional GIS analysis with emerging geospatial intelligence workflows (GeoAI concepts), especially in structured spatial relationship modeling.
