PROFILE
Yoonjin Hwang
Over three months, this developer contributed to the CausalInferenceLab/Lang2SQL repository by building foundational infrastructure for scalable LLM orchestration and unified database access. They began by onboarding a new full-stack developer and updating documentation to clarify team roles and project direction. Next, they implemented multi-provider LLM integration using Python and Langchain, enabling runtime selection among OpenAI, Azure, Bedrock, Gemini, Ollama, and Hugging Face, with environment-based configuration to reduce vendor lock-in. Finally, they delivered a modular database connectivity layer supporting multiple SQL databases, refactoring connection logic for maintainability and updating dependencies for Python 3.11/3.12 compatibility to streamline future integrations.
