I've built AI-powered systems including FaceQL, a scalable face retrieval platform with asynchronous image ingestion and high-speed vector similarity search using FastAPI, Celery, Redis, PostgreSQL, AWS S3, and FAISS.

For WellNest, I engineered a permissioned multi-organization EHR platform using the MERN stack and Hyperledger Fabric. I also developed a RAG pipeline with FastAPI, ChromaDB, and LLM integration to deliver context-aware responses grounded in patient records and medical references.

At LAOZ Global Assets, I contributed to an RWA Tokenization platform across smart contract development and backend APIs. I built and tested Node.js APIs, validated smart contracts through API-driven workflows, and reviewed contract logic for security vulnerabilities and gas-cost optimization.

I've also built and deployed Exo-Seek, a full-stack ML application for exoplanet classification using React, TypeScript, FastAPI, and Random Forest, achieving 92.7% accuracy and 89.2% F1-score.
