Wordpress Website Customization
Talha did an excellent job helping configure and refine our WordPress ListingPro directory site. He quickly identified setup issues, installed the correct importer plugin, and worked through the initial listing architecture to get everything running smoothly. Communication was prompt, the work was efficient, and he showed good problem-solving ability when troubleshooting the import feature.
I’d gladly work with him again on future MontanaPower.com development tasks. Highly recommended.
