Graduate student at UC Berkeley, assembling a portfolio and hands-on experience while completing a master’s degree.
A selection of class projects and independent work completed during my graduate studies at UC Berkeley, showing skills I am developing and experimenting with.
Built a RAG course recommender with transformer embeddings and Pinecone, improving relevance by ~50%. Developed course-data pipelines for vector search, degree filtering, and LLM recommendations. Exposed recommendation workflow through REST APIs and added cache for frequent courses and queries.
Built a custom Agar.io RL environment in C++ with Python/OpenAI Gym bindings and multi-agent support. Trained PPO actor–critic agents in PyTorch using spatial-grid states and configurable action spaces.
