What Our Clients Say About DevriX

Jon Reed


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!

Stuard Frank

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. Get in contact with them today, youll be in good hands.

Kris Gunnars

Founder, AuthorityNutrition

Before I started working with DevriX, I was having severe stability problems with my high-traffic website that gets over 10 million visits per month. They helped me migrate the site to a new webhost and fixed some code issues. Since then I’ve had a near 100% uptime, with an even faster site than before. The team at DevriX is highly knowledgeable about WordPress coding best practices and they always focused on clean code and fast loading times. I highly recommend working with them if you have a WordPress website.

Mario, Stanko and team are great to work with. We’ve worked with them on a number of complex, original applications, and can always count on them to bring extensive knowledge and skill to every project. They’re also very conscientious in their approach – always striving to build the most technically reliable solution. If you’re looking to create a robust software exactly to spec, then I’d highly recommend these guys!

Case Studies


Kustomer (now part of Meta) is a customer service CRM platform built for managing high support volume by optimizing experiences.

Kustomer has been working with DevriX on a WordPress development retainer plan since August 2019. Our mutual work was focused on the marketing side: building better looking pages and fixing various visual imperfections throughout the site. This, together with general speed and codebase improvements, which were highly needed, were two of our top priorities.

Major speed improvements across the website

Thorough UI improvements

A gradual reworking of the previous codebase

Obsev is a publishing site that hosts particularly viral entertainment and cultural commentary stories.

In November of 2018, they were doing significant traffic (30MM+ page views per month) and hitting a wall with scaling challenges. With these performance issues limiting their growth, it was imperative that we get them through the wall and remove the scaling barrier that was capping their growth and damaging their brand. Fast forward to today and they’ve more than quadrupled the traffic levels that were hobbling the site before.

More than quadrupled Traffic

Smart Meetings

Smart Meetings is a leading media company for professionals in the meetings industry.

We got in touch regarding a website migration from a custom platform built on top of Zend Framework to WordPress, rebuilding their theme to a responsive and clean layout, breaking their content down to over a dozen post types for different types of information, transferring their custom search tools to WordPress plugins and integrating several 3rd party systems. Our team broke down the migration script into multiple sequential iterations until the entire platform had been migrated.

Here is how WordPress retainers proved to be the optimal website redesign solution.

Density is a B2B company whose solution tracks anonymously how people use buildings and in-door spaces based on deep learning algorithms. Our task was to build a brand new corporate site used to present and sell the company's services and products and replace the one published on their domain at that time. Their current site was static and could not be updated easily but our team succeeded to launch the new site’s primary version within three weeks. Shortly after that, we pushed live Webinars and Blog features, tasks like documents (PDF), more advanced work with Marketo forms, the Kustomer's post type, and the Support page.
