Flutterflow Architect Needed for Simple Research App

This is a Flutterflow app called CARS which stands for Cybersecurity Awareness & Resilience Solution. I am a Phd student at NSU and I will be engaging in developmental research for microbusiness owners testing cyber awareness and resilience for their microbusinesses. This is intentionally a minimal research app. There is no backend all logic is handled in FlutterFlow + Firestore. The app enforces sequential viewing of videos and tracks completion and rewatch behavior only. The focus is on simplicity, reliability, and clean UX. Avoid over-engineering. There are 102 videos that have already been loaded via csv via Rowy into Firebase/Firestore. You already have: videoId title module order videoUrl and the videos are set-up to play sequentially one after another. If you get the job, I will provide the csv with placeholders for videourl for privacy. Please review the attached Developer Brief to get an idea of the specifics of this job. Thank you.
