- Developed a question-answering system over GitHub issues using OpenAI's Parallel Tool Calling API. - Implemented text-to-SQL tools and semantic search tools to build the question-answering system. - Used Pydantic models for separation of concerns, making it easier to evaluate tool selection separately from implementation. - Utilized Instructor for testing function calling capabilities before moving to implementation. - Discussed best practices for text-to-SQL generation and provided a prompt example for TimescaleDB-specific query generation.
