Projects

AlignmentSearch / Stampy Chat Python, Pinecone, MySQL

In March 2023, I developed a retrieval augmented generation (RAG) platform called AlignmentSearch, a conversational agent that curates the Alignment Research Dataset (ARD). When asked a query, we source relevant passages from a dataset of academic papers, books, articles, and other resources on AI safety and alignment. We then prompt GPT-3 to synthesize a response while citing back to these passages.

I set up a database for efficient querying of sources using Pinecone, optimized semantic similarity model by fine-tuning terminology-specific embeddings layer, developed automated MySQL database updates for multiple sources, and engineered question-answering assistant prompt for maximum accuracy and helpfulness.

Lifelogging Rust, FFmpeg, AWS S3

Developed a low memory, Rust-based continuous audio recording server for personal lifelogging. Implemented short-term disk persistence and long-term AWS S3 storage solutions. Integrated audio visualization and Opus compression for efficient data management. Optimized audio buffer writes using SIMD instructions, achieving 11.74x performance gain in benchmarks.
