An advanced, AI-powered interview preparation platform with real-time emotion detection that helps candidates practice and improve their interview skills.

A privacy-first AI file organizer that classifies and structures files entirely on-device via a 3-layer pipeline — rule-based matching, TF-IDF + k-means clustering, and a quantized transformer (all-MiniLM-L6-v2) in WebAssembly. Zero uploads.

Real-time fraud-ring detection that models accounts, devices, and transactions as a Neo4j graph. Multi-hop Cypher traversal with union-find clustering achieved 100% recall and zero false positives on seeded rings.

An IR pipeline that ranks the top 100 best-fit candidates from 100,000 profiles in ~27s, CPU-only. Aspect-based retrieval + Reciprocal Rank Fusion + cross-encoder reranking reach NDCG@10 of 0.952 while catching 80+ honeypot profiles.
