Azumo Reviews & Testimonials

Software Development Review from Michael S.
We selected Azumo to develop our software. We transitioned from another development company, so Azumo was initially responsible for migrating our existing code and environments. We are currently still working with Azumo as our nearshore software development team on adding new items to our software.

UI/UX Design Review from Anonymous
Azumo helped us migrate our existing UIs into a new framework, creating reusable components and the infrastructure needed for future development. The developer they assigned became a seamless part of our team, always punctual, responsive, and a great fit overall.

Software Development Review from Anonymous

IT Services Review from Taras Oliinyk
The project involved developing a mobile app for an e-commerce client, with U1CORE building the marketplace and WEZOM responsible for the mobile application. Both companies worked as partners on the same product, so the mobile app had to fit naturally into the marketplace's functionality. WEZOM brought solid mobile development expertise to the project and built the application around the marketplace requirements. Their team was able to work within the shared product setup and keep the mobile functionality consistent as the project progressed. We would be happy to work with WEZOM again on similar projects!

eCommerce Development Review from Ivan Usenko
We involved WEZOM to support the technical side of a U.S. e-commerce client's advertising setup. Our team handled PPC and marketing, while WEZOM implemented server-side tracking and profit-based ROAS attribution.Their technical work fit well into the client's existing setup and gave us a more reliable view of campaign performance. This made it easier to assess results and adjust advertising spend accordingly. Overall, we had a positive experience with WEZOM!

eCommerce Development Review from Max Zakhozhiy
For one of our jewelry e-commerce clients, WEZOM took care of the website development while our team handled its promotion. The teams coordinated well throughout the project, especially on technical requirements that could affect the websites future promotion. WEZOM was open to our input and made it easy to align development with the client's marketing needs. The finished website gave us a good foundation for ongoing promotion, and we were happy with how the two teams worked together. We'd be glad to collaborate with WEZOM again.

Software Development Review from Claus-Peter Mueller
We have engaged Infinum to develop an app that would digitalise our leasing process. From creating the initial offer through the necessary financing application and client identification to the final signature – all the steps required to successfully lease a vehicle or other object can be performed in-app, freeing the users of friction and having to deal with tedious paperwork.The app itself in the background has 30+ integrations, while keeping a seamless and quick to follow process on the front for our users. That application is in production and Infinum is responsible for maintaining it and further improving. After the initial development, we have additionally expanded our scope from vehicles to other equipment. They have also developed a Leasing widget, product which enables quick financing model while purchasing a vehicle online on car seller marketplace pages. At this moment, we are still in partnership with Infinum, and their engagement is mainly focused on localising the app to other countries and supporting us in our further business expansion. The work performed was done in Ruby on Rails and React technology, with support of other services.
Web Design Review from Anonymous

eCommerce Development Review from Jeffrey Weiss
I've worked with Table XI for the last 9 years on a University-wide system to manage transactions at over 70 centralized service facilities. It has been an outstanding experience. The system performs well and is rock solid. We've extended the feature set far beyond our initial scope and they've handled our needs without pause. My favorite part is the responsiveness. I've never been left waiting for a reply, and I have never seen an issue go unresolved in a short span of time. Great partners.

Software Development Review from Matt Frey
Table XI did a really good job kicking off the project by helping us with requirements gathering and project planning. They had some great exercises to facilitate this process and I particularly enjoyed how they teased out how flexible we were in terms of scope, budget, quality, and timeline. Doing so helped us ensure our expectations were all aligned prior to starting work. Table XI also maintains a great engineering culture, which was exhibited by their engineers.

Mobile App Development Review from Mark Otter
TableXI has supported Participate on a lot of different levels and in a variety of projects - ranging from project management to product development, user research, or design work - and we are a smatter and more equipped organization because of it. Our staff picked up lots of new skills by working with the talented folks at TableXI. All projects were delivered on time, with quality, and within budget.
