Dipl.-Ing. Elektrotechnik | 30+ Jahre Embedded Systems | Hardware & Firmware | ARM, STM32, Embedded Linux, RTOS, LabVIEW | Medizintechnik, Bahntechnik, industrielle Messtechnik | Verfügbar für B2B Remote-Projekte in Österreich.

ch bin Diplom-Ingenieur der Elektrotechnik (BME Budapest) mit über 30 Jahren Erfahrung in der Entwicklung eingebetteter Systeme. Mein Schwerpunkt liegt auf der Entwicklung kompletter Hard- und Firmwarelösungen – von der Hardwarearchitektur und Schaltungsanalyse über Embedded Software bis hin zu Mess-, Prüf- und Automatisierungssystemen.
Im Laufe meiner Tätigkeit habe ich Projekte für die Medizintechnik, Bahntechnik, industrielle Messtechnik und die Automobilindustrie realisiert. Ich arbeite sowohl mit Bare-Metal-Systemen als auch mit RTOS (FreeRTOS, embOS) und Embedded Linux. Zu meinen Kernkompetenzen gehören ARM Cortex-M, STM32, AVR, Renesas, Bootloader, CAN, Modbus, Low-Power-Design, Debugging sowie die Entwicklung von Mess- und Prüfsystemen mit NI LabVIEW.
Ich übernehme Projekte von der Analyse bestehender Systeme über die Entwicklung neuer Hardware- und Firmwarelösungen bis zur Inbetriebnahme und Fehlersuche. Dabei arbeite ich sowohl eigenständig als auch in internationalen Entwicklungsteams.
Besonders gerne unterstütze ich Unternehmen bei technisch anspruchsvollen Aufgaben wie der Modernisierung bestehender Embedded-Systeme, der Entwicklung energieeffizienter Geräte, der Integration von Hardware und Firmware sowie bei der Lösung komplexer technischer Probleme.
Ich suche Remote-Projekte oder langfristige Kooperationen im deutschsprachigen Raum, insbesondere in Österreich.
