Can you confirm which authentication method you want to use (e.g. email/password, OAuth, JWT-based auth) and whether user roles beyond admin are required for the final build?

Hi Kollin,
Before submitting a proposal, I’d like to clarify one point: is the £500 budget intended to cover the entire scope outlined in the brief, or is it allocated for a specific portion of the work?
Kind regards,
VahKollin K.19 Dec 2025Hi.
Nice to meet you.
Could you let me know that you understand all of this project?Vah D.19 Dec 2025Hi Kollin,
Nice to meet you, too.
Yes, I understand the project and its requirements clearly. The app is already in place with React and Express, and the remaining work is about finalising the existing features, polishing the UX and performance, adding the audio and admin functionality, and getting everything ready for a clean production launch.
Happy to answer any questions or discuss the next steps.
Kind regards,

Hi Kollin, Is the current codebase fully structured and documented, or will I need to audit and refactor parts before completing the remaining features?
