I Payment Rails

A unified Python interface to Uzbekistan's payment providers — Payme, Click, Uzum, Paynet, and Octo — collapsed into a single API with first-class support for Django, FastAPI, and Flask. What was a week of provider-specific boilerplate becomes a few lines.

II Passwordless Trust

Passkeys / WebAuthn for FastAPI. It performs the cryptographically sensitive ceremony — challenge issuance, signature verification, clone detection — and hands control back to you. Secure by default; out of your way by design.
