FAQ
Will this slow down my website?
No. I write custom, lightweight code tailored to your specific need, unlike pre-made plugins that load unnecessary scripts.
Do I own the code?
Yes. Once the order is complete, you have 100% ownership of the plugin source code.
Can you edit my existing theme/plugin?
Yes. I can create a "Child Theme" or a "Site-Specific Plugin" to override existing functions without breaking future updates.
