Practical, original write-ups on building secure Laravel backends: payment webhooks, wallet ledgers, REST API design and performance. Written by me, from how I build software.
Payment gateways deliver webhooks at least once, not exactly once. If your handler credits an order every time it is called, a retry means a double credit. Here is a pattern that stays correct.
A wallet is a ledger problem, not a CRUD problem. The rules that keep it correct are simple, but skipping any one of them leads to lost or duplicated money.
Good APIs feel boring to use: predictable URLs, predictable errors, predictable pagination. This is the checklist I run through before an API goes to production.
A page that runs fine with ten rows and crawls with ten thousand is often an N+1 problem. It is one of the most common causes of slow Laravel pages, and one of the easiest to fix.
Plenty of developers can make a Laravel page work. Fewer can build something that stays correct as it grows. These are the checks that separate the two.
If one of these topics is what your project needs, send me a short description and I'll reply by email.
