Diffed.gg

Diffed.gg is a SaaS platform that connects players looking for gaming services — such as coaching, boosting, or team play — with verified providers. The platform handles everything from discovery and secure payments to live communication and provider payouts.

I also integrated n8n automations to manage repetitive admin workflows like provider verification, payout approvals, and order notifications.
