Senior Ruby on Rails developer for payments, APIs and SaaS

Über mich
Senior Ruby on Rails engineer with eight years in production Rails. I build systems that handle money and keep working when the internet doesn't: payment integrations (Stripe with 3D Secure, PayPal, Amazon Pay, Apple Pay, Google Pay), multi-tenant SaaS and API-only backends on PostgreSQL or MySQL. I'm the founder and sole engineer of Hajza, a booking and point-of-sale platform live with paying venues in Pakistan and the UAE, and a Senior Backend Engineer on restaurant reservation software. Every change ships with tests. Message me before ordering and I'll confirm scope, price and delivery.
