Cross-border marketplace rails
5th yr · Python · payments · USDT · LLM · parsers · delivery
what I walked into
A cross-border marketplace where the service layer — payments, catalog, delivery — decides whether the business works at all. I own that layer.
what I shipped
Payment services including stablecoin (USDT) rails. LLM-powered catalog localization at real scale — cache keys and guard-rails, not vibes (I wrote up how in the log). Retail parsers built to survive markup drift. Multi-carrier delivery integrations with full order lifecycle.
status
In production, 5th year running — extended every year since 2022. Systems that keep working are the only portfolio that matters.
