Danish — Backend Development freelancer in Pakistan

TroponinIQ is an AI Chatbot Web and Mobile App that gives users direct access to the training and nutrition methods of expert coach Justin Harris. Pragmatic built this platform to turn decades of specialized knowledge into an interactive, on-demand assistant. The system uses a JavaScript-based MERN stack, with Next.js for the frontend and Node.js for the backend, to route user questions to AI models like Claude and Gemini. To ensure the AI provides accurate advice instead of general guesses, the team implemented a Retrieval-Augmented Generation (RAG) system. This system is trained on over 25 years of Harris’s specific content, including thousands of hours of podcasts, articles, and ebooks. When a user asks a question about contest prep or supplementation, the app searches this database for the relevant method and uses the AI to explain it clearly. This setup allows the tool to provide personalized advice that stays consistent with Justin’s specific formulas and training philosophy.
