Hello,
I am a WHMCS specialist. I have 10 years of experience in development with WHMCS
I have created many provisioning modules, addon modules & registrar modules for WHMCS.
I follow best coding practices in industry for a neat and clean code, with OOPs. I use in-built whmcs api functions and provided database functions, so that the module can work even after whmcs/php version updates.
You can check my reviews, for the WHMCS jobs I have done.
Regards
