About
Markoto Sajidman holds a degree in mechanical engineering (Dipl.-Ing.) from the University of Karlsruhe (TH), with a focus on measurement and control engineering. His diploma thesis addressed fuzzy-logic-based control of mechanical drive systems.
From 1993 to 2000 he worked as a research engineer and project leader at a German applied-research institute, developing intelligent control systems for a manufacturer of quartz-glass tubes and optical-fiber preforms — from initial concept through to deployment in live production. Since 2000 he has practiced as an independent engineer and continues to work with the institute as a freelance associate to this day.
Three decades in industrial control
Current focus
As a freelance associate of the institute, Markoto Sajidman is the lead controls and software engineer for the production automation of a global manufacturer of quartz-glass tubes and optical-fiber preforms, with production sites in the USA and Germany. His control software runs on all eight glass-drawing towers of the main production site.
Next-generation preform processes
Development and full automation of novel drawing processes for hollow-core and multicore fiber preforms, taken from first trial to production-ready, recipe-based automation.
Control platform modernization
Migration of the control platform from legacy VXI instrumentation to PLC and HMI systems, operating-system upgrades on all control computers, and integration with the client's IoT platform via OPC UA and MQTT — without interrupting production.
Monitoring, safety and data
Automated detection of oscillations, disturbances and anomalies with protective control responses; safety shutdowns on crack and sensor faults; part-number-based KPI databases and automated post-run reporting.
Engineering practice and continuity
Git-based development with code review and re-simulation of historical production data before every release; source-code documentation, training material and knowledge transfer to the client's engineering team.
Track record
Professional profile
Project Leadership
