looking for someone who can fix AI chat bot

My AI chatbot is online but replies are often empty or wrong, so something inside the intent-handling flow clearly needs attention. The stack is Python 3.9, FastAPI, Rasa NLU/dialogue, Redis for session state and everything runs in Docker on AWS ECS. I can share the private repo, a set of failing conversation logs and CloudWatch traces the moment we start. What I need you to do is dig through the codebase, isolate the bug that keeps the bot from responding correctly, and deliver a clean patch or pull-request that restores consistent, context-aware answers. Deliverables • Fixed source code (or PR) that restores correct responses • Short technical summary of the root cause and your changes • Proof: the supplied test conversations return the expected answers and a 30-minute free-flow chat runs without fallback triggers If you have tackled a similar issue before, let me know what you worked on and how you approached the fix; that will help me pick fast. Access will be granted as soon as we agree, and I’m ready to test the moment you push the update.
