Hi,
As an experienced WordPress developer with over 6 years of experience, I have successfully incorporated custom attribute filters into various websites, similar to your requirements. My expertise includes working with CSS, HTML, JavaScript, PHP and WordPress. This enables me to create custom filters that seamlessly integrate into your existing design while providing users with intuitive options to filter their search.
One aspect I particularly pride myself on is my ability to teach and empower my clients. In line with your requirement, I can not only add the filter but also teach you how to customize it in the future. I strongly believe in fostering transparency and long-term relationships with my clients, thus ensuring their complete control over their website post-development.
Looking at the attachment you provided, I already have ideas on how to create a filter that aligns perfectly with your preferences. Moreover, my specialization in eCommerce solutions further strengthens my understanding of the importance and impact of such functionalities for online businesses. If you're after a skilled WordPress freelancer who can tackle this task promptly, and efficiently and provide valuable knowledge for future customization.
Regards,
Rajat Pathania
