AlgoWars
Real-time 1v1 competitive coding battles
The Technical Challenge
Traditional coding challenge websites are asynchronous, solitary, and slow. The founders wanted to create an adrenaline-fueled, synchronous 1v1 esports arena for software engineers with sub-second matchmaking and secure code execution across multiple programming languages.
What We Designed & Shipped
MarketBaddies designed and engineered AlgoWars from the ground up: an ultra-fast competitive platform featuring real-time WebSocket state synchronization, an isolated multi-language code runner sandbox, and a mathematically rigorous ELO matchmaking rating system.
Engineering Breakdown & Implementation
- Sub-50ms bidirectional WebSocket communication powering live dual-code streaming and opponent keystroke telemetry
- Sandboxed remote code execution worker pool running untrusted user submissions in secured, resource-capped containers
- Redis-backed in-memory matchmaking queue calculating skill-balanced pairings using ELO algorithms
- PostgreSQL persistence with comprehensive match history, replay recordings, and global leaderboards
- Live at algowars.online with real engineers battling in 1v1 competitive duels
- Sub-100ms average round-trip test case execution feedback
- Zero downtime during multiplayer peak tournament events
