Zoltán Ujvári

From 1971 he worked at the Videoton Development Institute (VIFI); in 1972 he became head of the Data Transmission Department (the department's task was to localize and develop the telecommunications and local hardware devices of the VIDEOTON computer family, which was developed using a license purchased from the French company CII/SEMS). In addition to his managerial work, he developed the factory-level remote data processing strategy.
In 1980, he was head of the Hardware and Systems Engineering Department (localization of the SEMS S series, development of microprocessor-based process control systems, development of design versions of VT computers).
He personally contributed to the development of a production control system developed for the Ministry of Gas Industry of the Soviet Union - together with the French company TECHNIP - in which communication was carried out by VT600 computers, and direct process control by VT industrial process control microcomputers (RPT series). He participated in the creation of a packet-switched network consisting of 3 VT60 nodes based on X.25 (Budapest - Székesfehérvár - Tab). He was the initiator of the development of the VIDEOTON-developed UNIX operating system workstation family (VT32,320,3200) intended for office and CAD (Computer-aided Design) applications.
He and his colleagues reported on their results in presentations at COMNET conferences (1988, 1981).

Between 1986 and 1990, he was the chief engineer of VIFI, responsible for the Institute's extensive hardware and software development activities.

In 1990, he and his partners founded FlexiTon Ltd. (data support for telecommunications network developments, digitized maps for network planning, spatial models for mobile network planning, optical network registration software), where he was technical director between 1990-92, then managing director until 2005, and then technical director again until 2013.
