Coding support: React, TS and Google Apps integration

I need someone to *help* me build a mobile Web app. The app is React/TS and uses Gemini to analyse a photo or voice memo and then add an appointment to Google Calendar or a contact to Google Contacts etc.
I have got some way using Google AI Studio and can share code with Github.
Important: I am not a dev. I've coded a long time ago but don't my way around modern environments and languages. I need someone with good English who knows the technologies above but who can also explain what they're up to and be patient with me while I learn how to do stuff myself.
I can't really define deliverables so you must just call credits off the amount which I'm considering a trial. If it works well I would expect to extend.
