Who we are

About Xari

An engineering team that trains, consults, and builds — best known for DevExpress XAF, and just as at home shipping complete products across mobile, web, IoT, firmware and security.

Built by people who care about the craft

Xari is a team of engineers, consultants, trainers, and builders with deep experience across XAF, .NET, cloud, mobile, firmware, AI, and product delivery. We work closely with clients, share knowledge generously, and bring the same engineering discipline to training, consulting, and development work.

Leadership

XAF is not only our work — it is our passion.

Jose Javier Columbie

Microsoft MVP

Jose holds a Master's in Electrical Engineering and is a .NET architect and Microsoft MVP. He leads Xari's training, consulting, and Azure enterprise development, with a deep focus on performance, data access, and application design — and DevExpress XAF and XPO at the heart of almost everything he builds, across desktop, web, and mobile. A frequent speaker and blogger, he's a tireless advocate for the XAF community.

Joche Ojeda

DevExpress MVP

Joche is a DevExpress MVP who has worked with XAF and XPO since their earliest days, starting with XPO back in 2005. As a lead developer he evaluated frameworks to build a unified ERP and, when XAF arrived, was hooked. He remains a dedicated XPO advocate, using it across ASP.NET MVC and Core, Xamarin, and more recently the Uno Platform.

What we do

Xari is an IT consultancy and software engineering company. We are best known as DevExpress XAF specialists — training teams, consulting on the tough problems, and building line-of-business apps on the framework we love. We also design and build complete products end to end: mobile, web, IoT, firmware, electronics, and security. Across all of it we bring the same engineering discipline and one simple goal — clients who feel supported, productive, and glad they chose us.

Global reach

Xari's customers and students span the globe — a testament to the depth of XAF and the reach of the community.
