Python FastAPI backend developer crypto payment integrations

About me
I build backend payment infrastructure in Python: FastAPI, SQLite/PostgreSQL, Docker.
My speciality is stablecoin payment reconciliation that never touches your keys. Exact-amount invoice matching, confirmation policies, restart-safe chain scanners, and HMAC-signed webhooks that retry until they land. Every claim I make is backed by a test you can run.
I work asynchronously, in writing. Send your requirements and I reply with scope, a fixed price and milestones. No calls, no meetings, no screen sharing.
Most recent build: a self-hosted USDT TRC20 reconciliation service, 117 passing tests.
