In early January 2018, the company Factory X d.o.o. became a Microsoft Gold Certified Partner, the most highly accredited partner for the development of applications using Microsoft technologies, and attained the Gold Application Development competency. For the 4th consecutive year, we have confirmed this status in January 2022. It is a testament to the expertise of the employees of the company Factory X d.o.o. as well as to their professional conduct in the realization of various development projects using Microsoft technologies. Gold Application Development is the highest level of competency for companies that deal with software development (ISV – Independent Software Vendor). Apart from at least four MCSD (Microsoft Certified Solution Developer) certificates, the competency requires a portfolio of a certain number of complex and demanding projects. Projects by which Factory X d.o.o. continues to successfully confirm their expertise have been done for clients from Germany, Switzerland, Austria, the Netherlands, and in those projects, the company Factory X d.o.o. demonstrated its focus on advanced technologies and being up-to-date with contemporary trends. Attaining the Gold Application Development competency would not have been possible without professional and responsible employees, who are the greatest asset of Factory X.
