Senior WordPress & WooCommerce developer with 10+ years of backend experience, specializing in REST API integrations and custom plugin architecture.
I connect WordPress to external systems that need to run reliably in production: CRMs, ERPs, payment gateways, custom APIs, and AI tools like OpenAI/ChatGPT.
I focus on clean PHP code, proper authentication, error logging, and long-term maintainability. I treat your live store with care, never take shortcuts, and build code that lasts.
Message me with your requirements and I'll confirm feasibility within an hour.

FAQ
Will this plugin continue working when WordPress or PHP updates?
Yes. I write clean, modern PHP following official WordPress Coding Standards, using core hooks (actions and filters) rather than hardcoded hacks. This ensures your plugin remains stable across future WordPress core and PHP version updates.
Can you modify a third-party or premium plugin without breaking future updates?
Yes. Whenever possible, I write custom companion plugins or child-theme functions that hook into the existing plugin's API and filters. This way, you can safely update the parent plugin without losing your custom modifications.
Will this custom plugin slow down my website?
Absolutely not. Unlike bloated commercial plugins that load dozens of unnecessary scripts, custom plugins only execute the exact code your feature requires, resulting in zero bloat and lightning-fast execution.
How will I install and manage the plugin?
I deliver the plugin as a standard, ready-to-use .zip file. You simply go to your WordPress admin dashboard → Plugins → Add New → Upload, and activate it with one click. If requested, I can also install and test it on your staging environment for you.

He did a perfect job, customizing one function that was important to me in the Learndash plugin, giving a better and faster solution that I imagined. 100% satisfied with him and, for sure, I will come back when I have other needs.
