Things I've Built

Interactive AI/ML portfolio with a procedurally animated 3D cartoon character built in React Three Fiber. Toon shading, scroll-driven GSAP animations, Lenis smooth scroll, and SplitType text effects. The character responds to mouse position, scroll depth, and hover zones in real time.

12 crash hotspot clusters identified via DBSCAN + Haversine distance on 33,228 Long Island accident records. 4 driver-risk archetypes via FAMD + k-Means. XGBoost severity classifier: AUC-ROC 0.7185, 71% accuracy, 5-fold CV 0.7164 ± 0.0042. SHAP per-cluster attribution + GeoPandas/osmnx road-graph overlays for logistics risk scoring.

Voice-first ENS rare-disease monitor that won HackRare 2026. Retell AI automates daily patient calls; Claude Haiku extracts 7 validated clinical scores per call. Tri-level ML pipeline: Global Random Forest → Personal RF → Z-score override. FastMCP server integrates with a Next.js doctor dashboard for real-time anomaly alerts.

33% accuracy improvement via Prophet + XGBoost + ARIMA/STL ensemble forecasting with P10/P90 confidence intervals. Redis Pub/Sub + WebSocket architecture eliminates HTTP timeouts on 5–30 s ML inference. War Games simulator stress-tests 4 economic scenarios. A2UI/MCP AI Analyst Agent renders interactive React charts in chat. Full 7-service Docker Compose stack with Nginx reverse proxy.

Multimodal RAG assistant with 16 agentic tools — vision, DALL-E 3, stock data, live news, and 100+ language translation. 7.5× STT latency reduction via Groq LPU (1,500 ms → 200 ms). FAISS IndexFlatL2 + HuggingFace Sentence Transformers over PDF/DOCX/CSV/PPTX. 4-layer heuristic recovery pipeline cut agent failures 90%.

Solidity escrow smart contract deployed on Ethereum Sepolia — dual-party approval logic with deterministic fund locking. React + ethers.js + MetaMask frontend. Hono.js + Cloudflare Workers serverless backend with Upstash Redis for metadata indexing. Hardhat test suite validates all 7 contract state transitions.
