I want to run a quick proof-of-concept that lets me gauge how smoothly we can collaborate on larger AI builds. The assignment is deliberately small: • Frontend – a single Flutter screen with a neat, minimal interface: one text field, one “Generate” button. • Backend – a lightweight FastAPI service exposing one POST endpoint that accepts the text, calls any straightforward language model (OpenAI, Hugging Face, or something comparably simple), then hands the generated text straight back to the app. • Flow – user types → hits Generate → sees the model’s response immediately in the same view. Please organise the code in clearly named folders, add concise README files for both sides (setup, run, and any env-var notes), and keep everything runnable on macOS or Linux with standard tooling (Flutter stable channel, Python 3.10+ with uvicorn). Turnaround is 48 hours from award. I will create a single $150 milestone up front and release once the project builds locally, the endpoint responds, and the UI shows the return string without hiccups. If this goes smoothly, it will open the door to far more ambitious AI-driven mobile work together.
