A full-stack Spotify management platform with OAuth, hourly playlist sync, and a SQLite history layer — deployed with Docker Compose and GitHub Actions. Resolves duplicate tracks by ISRC/title, mixes playlists with a weighted shuffle (batched for Spotify’s API limits), and uses Gemini to flag misfiled songs against your playlist intents.

Scrapes Rate My Professors via GraphQL, embeds reviews locally with sentence-transformers, and stores vectors in ChromaDB for semantic search. Course- and professor-aware filters (e.g. CS220) narrow evidence for recommendations and Q&A, then Groq’s Llama 3.3 returns cited answers in a multi-mode Streamlit app.

Team-built React Native app with @umass.edu-restricted Supabase auth and dynamic event filtering across campus. A FastAPI pipeline scrapes and syncs events every two hours (paginated API, SQLite dedup, under 10s sync latency). Regex location parsing mapped 50+ buildings and 30+ raw event types into 10 categories, cutting parsing errors by 90%.
