Case Study
Payment & Subscription Systems
Stripe and Laravel Cashier for subscriptions, webhooks, and billing flows where mistakes actually hurt.
- Stripe
- Laravel Cashier
- Webhooks

Problem
Products needed payment and subscription handling that stays correct when real money is involved.
Context
Apps using Stripe and Laravel Cashier for customers, subscriptions, payment events, and keeping local state in sync.
Challenge
Lifecycle edge cases, failed payments, webhook reliability, and keeping the app aligned with Stripe.
Approach
I built and maintained billing flows around Cashier/Stripe primitives, webhook handling, and application updates driven by payment events.
Result
Billing systems where correctness and reliability matter more than shiny new features.
Lessons
In payments, webhooks and lifecycle events are the real product surface.
