Case study
An AI coaching PWA with Supabase authentication and data, Groq inference using Llama 3.3 70B, and private network deployment.
Photography shows industry context, not the client’s premises or a product screenshot.
The context
The coaching application is a delivered AI coaching PWA for fitness. It combines an application interface with Supabase authentication and data.
Groq provides LLM inference with Llama 3.3 70B. The private network deployment of the application is distinct from the location of model inference.
The challenge
Connect a coaching PWA to authenticated user data and Groq model inference.
Keep private network application deployment distinct from the external inference request.
Present the Llama 3.3 70B coaching capability through a usable browser application.
The solution
Delivered functionality and implementation boundaries.
01
The progressive web application is the user's entry point to AI coaching. It brings browser-based interaction together with the authentication, data and inference components. PWA delivery describes the application surface; model inference is a separate part of the request flow.
02
Supabase supplies authentication and application data. Identity and the information used in a coaching interaction must be considered together: knowing who the user is and deciding which information an interaction may use are related engineering responsibilities.
03
The coaching integration uses Groq and Llama 3.3 70B. The application presents the interaction while the model produces language output. A model response is assistance within the coaching product, not a guarantee of a training outcome or a substitute for medical care.
04
The application is deployed on a private network, while Groq supplies external LLM inference. Application access and model processing therefore have different boundaries. The private application boundary controls access; the inference boundary determines what information leaves the application for model processing.
Core functionality
Technical implementation
The PWA is the coaching interface. Supabase provides identity and data, and Groq serves Llama 3.3 70B inference. The application was deployed on a private network; inference is an external service call. Private application access does not mean that model processing occurs on the same network.
