• AI Orchestration: Implement scalable state machines and orchestration logic utilizing LangGraph and LangChain. 

• System Architecture: Apply Clean Architecture principles to ensure clear separation of concerns across Domain, Application, and Infrastructure layers. 

• Real-time Interactions: Develop real-time data streaming features using Server-Sent Events (SSE) for dynamic frontend UI commands and progress tracking. 

• Integrations: Build secure and scalable integrations with internal enterprise systems and handle complex authentication mechanisms (JWKS-based JWT, TPAuth). 

• Database Management: Design data persistence strategies and TTL-based caching using MongoDB (Motor) and cachetools.
