Clement provides excellent suggestions and feedback of his own. I have also questioned whether or not he sleeps because his response time and availability has been impeccable. Clement’s work is both functional and practical. He is an easy recommendation for me after the experience I have had. Thank you.

We only had an idea, he took that idea and created a great website. Any modifications or requests he made, he immediately jumped on it and was willing to continue working on it until it was exactly what we wanted. We enjoyed working with him because of his patience with us and he created a great website. Definitely will be working with him once we expand and grow as a company.

Dynamic shuttle seat reservations are highly complex, but Clement coded custom PHP plugins over WooCommerce that prevent double-bookings, adjust dynamic rates, and notify clients via Twilio. Direct checkout sales skyrocketed by 180%!

Our mobile bounce rates were failing due to bloating third-party apps. Clement cleaned up our theme scripts, optimized our script priority queue, and hand-coded native Liquid upsell cart drawers that load instantly. Checkout abandonments dropped by 18%!
