Hello, ready to create this plugin.
---

Creating templates, plugins from scratch.
Working with such plugins, as well as customizing them for specific needs:

Ready to take on the implementation - I will create a full-fledged WordPress plugin with an admin panel, PDF certificates, QR codes, and a verification page /verify/.
I work cleanly, with security (HMAC-SHA256), adapt the design to your template, and provide a clear installation instruction.
I guarantee accuracy, speed, and a result that can be immediately shown to clients.
Sincerely,
Andriy

Good day.
I have experience and a desire to work.
I will complete it within the agreed deadlines.

I will implement the functionality according to your technical specifications: generating unique codes and QR codes, creating PDF certificates based on a template, a verification page /verify/, and an admin panel for managing certificates. I have experience in developing similar solutions and ready-made tools for generating QR codes and PDFs. I will do everything exactly as described and with clean, secure code. There is no ready-made plugin that does everything at once (PDF + QR + verification + certificate revocation) available publicly — usually, this is written for the specific tasks of a company. But I can: use proven libraries (mPDF, endroid/qr-code); integrate them into your custom plugin; create an installation ZIP that can be installed via WordPress.
