πŸ‘‹ Hi, I'm Devanshu Khadka

I'm a Master's student in Applied Data Science at the University of Chicago and a Computer Science and Computational Modeling and Data Analytics graduate from Virginia Tech. I enjoy building data-driven systems and scalable applications that bridge software engineering, analytics, and cloud technologies.

Across academic, research, and internship experiences, I have worked on data pipelines, automation workflows, and full-stack applications. I focus on writing clean, reliable code and turning raw data into structured, usable insights that support real-world decisions.

πŸ”§ Featured Projects

  • πŸ™οΈ Oasis – Small Business Survival Intelligence:
    ML-powered platform predicting small business closure risk using XGBoost + SHAP explainability on Chicago open data. Features a 3D Mapbox dashboard, multilingual AI consultant (Gemini + Groq fallback), and voice-enabled insights with PDF reporting. Built with FastAPI, React, and deployed via Docker on DigitalOcean. WildHacks project.

  • 🧠 Anchor – AI Focus Companion:
    Real-time AI system that detects task drift using window activity + webcam signals, and delivers personalized interventions via an intelligent agent. Built with FastAPI, React, WebSockets, and multi-model reasoning (Markov chains + LLMs). Yale Hackathon Project.

  • πŸ₯ Clinical KG Extraction – UChicago AI+Science Hackathon:
    Multi-agent pipeline extracting clinical knowledge graphs from doctor-patient transcripts. Built a 5-stage architecture (chunker, dual extractor, schema enforcer, critic, refiner) scoring 0.848 composite on 20 patients and 0.857 on unseen holdout data. Added Whisper-based audio timestamp tagging linking every KG node to the exact moment it was mentioned in the recording.

  • πŸ”¬ Cell Nuclei Segmentation:
    Instance segmentation of cell nuclei in microscopy images using the pre-trained Cellpose model. Evaluated performance on 50 paired images with metrics (Precision, Recall, F1, Dice) and visual overlays.

  • πŸ₯ ER Wait Time Forecasting:
    Time series forecasting model for EMS dispatch wait times using XGBoost and NYC Open Data. Focused on healthcare analytics and model explainability.

  • ✈️ Airport Delay Forecasting:
    Time series forecasting of U.S. flight delays using SARIMA models, STL decomposition, and feature engineering on 26M+ flight records to analyze airport congestion dynamics.

  • πŸš— Crash Rate Prediction:
    Full-stack web app to predict crash rates using TensorFlow, FastAPI, and React.

  • πŸ•ŠοΈ AI Web Scraper for Parish Data:
    ETL + LLM-powered scraper with Power BI dashboards for Catholic Leadership Institute.

  • 🌍 Landslide Prediction:
    Tree-based classification model to predict landslide-prone regions using NASA GLC data.
