Hi there, I understand you want an AI-powered role-play sim that fits into Skillsincloud, with a strong conversational engine, scenario builder, real-time feedback, and seamless Rails/Vue integration. I’ll build a robust backend using Ruby on Rails and a responsive Vue frontend, wired to LLMs (OpenAI/Anthropic) with prompt engineering and RAG to keep chats context-aware. The Scenario Builder will define Personas, objectives, and emotional cues, while the feedback module analyzes sentiment, keywords, and goal progress to guide users. AWS will host and scale the solution, with S3 for storage and smooth deployment alongside your current stack. The result is a polished, immersive training tool that you can extend beyond Phase 1 to include avatars later. 1) What are your top five buyer personas for initial scenarios, and what key signals define each persona? 2) Do you require per-user data isolation or can we share datasets across tenants? 3) Which Rails/Vue versions are in use, and are there any coding standards or linters you want enforced? 4) How should the scoring rubric for performance be structured (weighting for sentiment, keywords, and goal achievement)? 5) Do you have preferred OpenAI/Anthropic models or a budget cap for API usage? 6) What are your non-negotiable security/compliance requirements (data retention, access controls)? 7) Do you want offline fallback or caching for response times under peak load? 8) How will you handle content moderation for sensitive topics

Hello, I specialize in AI-powered conversational systems and built and customized large scale role-play simulation engines using OpenAI, RAG pipelines and Rails backends for training platforms. The main challenge here is making the AI feel like a real human conversation partner, not a chatbot, especially when handling emotional triggers and persona switching mid-scenario. I am certified in prompt engineering and RAG architecture development and I will solve this by building a layered context system where each persona carries its own memory, tone and behavioral rules throughout the conversation. Few things I would love to know. How are you planning to score user performance, is it real-time during the conversation or after the session ends? Are the personas fixed templates or should trainers create custom ones? And does your current Rails and Vue setup use ActionCable for real-time communication or something else? I can also structure the scenario builder so it becomes reusable for any future training module you add beyond phase one. Happy to show similar AI simulation work I shipped. Available to start right away. Best regards, Dev S.
