Backend engineer focused on the parts that are expensive to get wrong: billing, payment webhooks, auth and LLM features. Sole engineer of the production platform behind an online school with 300+ active students a month (site, CRM, LMS, payments), and of a CRM + LMS for a study-abroad company used daily by 25 staff across 3 branches.
Public billing core: https://github.com/alt-f6/edtech-billing-core (append-only ledger, race-safe payments, 104 integration tests on real Postgres; a randomized test caught a real double-refund bug).
Looking for a long-term remote contract with a US or EU team.
