Okiyumi Rent — system viewplaceholder media, TODO(user): screenshots

Context

Account rental is an operationally heavy business: orders arrive from marketplaces around the clock, every order needs instant, correct issuance, and mistakes cost money. The system was designed to run the whole operation without manual intervention.

Build

The core is a multi-tenant issuance engine: every tenant gets isolated data and configuration, while the order pipeline — payment confirmation, account issuance, renewal, refund — is centralized and race-protected.

Marketplace orders (FunPay) and direct Telegram orders converge on the same pipeline, so business rules live in exactly one place.

TODO(user): what happened after launch — tenants, volume, what you'd highlight.
