Firebase expert needed

Hello. I am sure that I'll finish your project successfully with my experience. I am a senior full-stack developer who has 8+ years of development experience. I specialize in node.js and Google firebase(auth, db, function, storage). If you are interested in me, please contact me anytime. Looking forward to your reply. Best regards.

Hello, I offer you my experience and skill working with Firebase on a regular basis. I can carry out the task you need and I am waiting for your message on the chat to specify the details.

i read your description and I have a long experience with node js and firebase i can upgrade your exisiting code base to latest node and firebase version and the duration depends on how big your code base is but i think 10 days are enough

Hey, Firebase is telling the developers to upgrade the firebase functions from Node.js 8 to Node.js 12 as they will discontinue Node.js 8 very soon. I've upgraded this before and I can do it easily. There are some storage problems associated with latest node.js version and being an experienced in it, I know how to avoid the issues when upgrading it. Thank You
