The problem

Streamers juggle several tools to get overlays and effects on screen while they're live.

What I built

I built the paid plans: 4 packs and add-ons, each with monthly and annual billing and its own limits, renewing automatically by card or GoPay through Midtrans without ever charging twice. I also built Google and Discord sign-in, rate-limited sign-ups, and TikTok chat commands that add songs to the streamer's Spotify queue.

The result

I found and fixed a bug that over-counted viewer gifts by 51%, so leaderboards and gift goals are now accurate.
