I build production backend systems at Hatom for vehicle fleet operations, customer onboarding, subscriptions, payments, licensing, and product entitlements.
I've developed Laravel REST APIs, a configurable rental pricing engine, payment and invoicing workflows, authentication systems, multi-channel notifications, PDF documents, and reporting for revenue, reservations, fleet utilization, and customer insights.
I also built an internal TypeScript and Node.js CRM and entitlements platform plus a multi-tenant payment gateway, focusing on secure integrations, reliable background processing, observability, test coverage, and maintainable architecture.
