Platforms

Web

Double Jump gameplay with several players in a level, the in-game chat prompt visible.

Still from the project.

The challenge

Real-time multiplayer and blockchain integration pull in opposite directions: one needs low latency and stable session state, the other needs on-chain transactions that are slow and can fail. Both had to sit behind normal gameplay.

What I did

Designed multiplayer logic and the real-time chat system.
Deployed the backend on Kubernetes (GCP).
Integrated NFT minting with Solana and Magic Eden cross-chain.
Mentored junior engineers on the team.
