Senior PHP 8 developer — APIs and payment systems

I am a senior PHP developer with eight years of commercial experience, and almost all of that time I have been working on backend — the part of the product that must work reliably when it comes to real money and real users. My main profile is payment system integration and REST API design: from database schema to gateway integration, webhook processing, refunds and correct operation under load.

I write in modern PHP 8 — I use Laravel or Symfony when the framework actually simplifies the task, and clean PHP where a lighter solution is needed. In any case, I treat security as a mandatory part of the work, not as an addition: I rely on OWASP Top 10 and check every point where user input meets the system. I can lead a project all the way — from planning to deployment — or join an existing team and take the backend load off without a long onboarding period.

I value communication just as much as code: I keep the customer informed daily, warn about risks in advance and leave clear documentation after myself.
