Required Firebase,Firebase Cloud Firestore freelancer for Firebase firestore functions job

I am developing a web app using firebase and I use cloud firestore for it.

I have a specific feature to be built that requires firestore functions. I need someone to help me with writing the few lines of code for this feature and also teach me about the same.

The webapp already has a few features.

For someone who knows firestore functions, this will not take more than an hour or two.

P.S - I am a developer myself.
