TallyUp PvP Mini-Games Platform

Started from scratch. Built the technical foundation for five games across mobile, web, and Telegram. Led a team of 4 engineers. The hard part wasn't the games—it was the server-authoritative multiplayer handling 30–40 tournaments with 2,500 players each. Shipped it, scaled it to 2,500+ concurrent users, kept it running.

• Built server-authoritative multiplayer so players couldn't cheat
• Created Vue admin portal that let us manage tournaments without code changes
