Developed backend features for livekit/agents and mem0ai/mem0, focusing on robust API development and Python-based solutions. In livekit/agents, introduced a strict tool use schema for Anthropic LLM tool integration, enabling precise parsing and validation of function tools to improve reliability, safety, and user experience. For mem0ai/mem0, delivered a structured input flow for the memory update endpoint, allowing organized text and metadata updates while refactoring input handling to enhance data integrity and scalability. Emphasized backend development, testing, and maintainability throughout both projects, laying groundwork for future extensibility and reducing complexity in tool and data integration workflows.
