Austin Opia | Senior Laravel Engineer & Technical Lead

Overview

About the project

Built the whole back end for a laundry pickup-and-delivery client at Geeks For Growth. Customers register with a card on file, book single or recurring pickups, and are charged off-session when an order is fulfilled. A scheduled command generates recurring orders, a capacity service caps how many orders a pickup date can take, invoices are generated per order, and customer profiles sync to Klaviyo for marketing.

Challenges & solutions

Challenges

01Charging customers after the service is delivered, not at checkout
02Recurring orders that must appear on schedule without manual work
03Overbooking popular pickup days

Solutions

01Stripe SetupIntents at registration, saved payment methods, off-session charges and a signed webhook handler
02A scheduled GenerateRecurringOrders command, plus endpoints to convert a single order to recurring
03OrderCapacityService that checks a pickup date’s limit and returns the remaining slots before an order is accepted

All Projects Work with me on something like this
