PROJECTS_&_STATS

MindMapper

React · FastAPI · OpenAI · Docker

AI-powered tool that converts PDFs, notes, and docs into interactive mind maps. Uses semantic chunking with OpenAI embeddings + ChromaDB to link related ideas and lets users explore knowledge in a sideways, depth-first way instead of linear chat.

Slander

WebRTC · Node.js · Algorithms · AI

P2P real-time video chat platform for college students with user verification, abuse detection, and matchmaking algorithms. Tuned WebRTC to achieve ~200 ms end-to-end latency and a smooth blind-date experience at scale.
