Best way to create a polling system?

Hey, I am working on a voting system for a big streamer so that they can poll operators from their chat. I am currently using upstash redis and want to do realtime fetching but can't figure it out. Is this the best way to create a system like this? Should I use an additional backend like fastify? Currently I am storing the results from the chat into a hashed table. Right now im just hetting the data and parsing it and typing it.
