Testimonials from our happy customers


Jon Reed

I’ve been working with web design firms since the mid-90s. DevriX is the best I have worked with by a wide margin. Their ability to customize high-performance WordPress sites is the best value I’ve seen. They bring a spirit of collaboration to their work, as well as taking initiative on virtual project management. It’s extremely rare to work with a firm that has both development and design chops.

DevriX has been able to add sophisticated functionality to while maintaining a very high mobile-first design standard. That’s a tough balance to maintain. One remarkable thing: I have never met the DevriX team. We have never even spoken on the phone or VoIP. Another member of our team has spoken with them, but the point is I’ve been able to get projects done with DevriX that involved complex design requirements without ever talking real-time. That requires an exceptional attention to detail. I cannot recommend DevriX highly enough.


Adam Sewall

VP Marketing, Verkada
DevriX enabled us to deliver an entirely reimagined B2B website in under 3 weeks. From backend integrations to mobile layouts on the frontend, I was continually impressed with the team’s knowledge and, equally important, ability to think like a user.

The engineers weren’t just completing deliverables — they were proactively suggesting solutions to our challenges, and filling in gaps where requirements were incomplete or unclear. Communication was clear and effective throughout the course of the project. Highly recommended for teams looking to move fast!

Mario and his team are flat out awesome.

They’ve been able to handle the most difficult challenges we’ve thrown at them whilst all the time offering a level of expertise and command of their subject area way beyond that offered by your average freelancer or small agency.

In fact, i’d wager you’d struggle to find such committed and skilled workers at this price point anywhere else, putting them easily on a par with some of the leading WordPress dev shops but at a fraction of the price.

Whether you’re looking for a team to make your next big project a reality or to further develop or stregthen an existing project then you won’t be disappointed with what Mario and the DevriX team have to offer.

If it was not for Stanko’s patience, I would still be misunderstanding simple instructions. Can I be dumb and difficult. You guys are the best.

Jordi Lopez

CEO of Kopelia
I want to take a minute to thank Mario for the timely work done on our catalog system. The previous version system had performance problems. The response time of Mario was perfect and he tuned all the system to improve the performance. Now the performance of the system is ok. I just want to say thanks for a job well done!
