 My current project is a biomedical Mobile X-Ray System. I am responsible for design and development of the embedded part of the device. The project is being developed according to IEC 62304 medical software standard.

 Also, I played a key role in development and successful delivery of my previous project, which was an industrial sewage pump SCADA Programmable Logic Controller (PLC) for South East Water, one of the largest water and sewerage providers in Melbourne area. 

The SCADA PLC supports DNP3 communication protocol over TCP and runs SCADA programs created in Schneider ISaGRAF Workbench IDE. It operates as a remote SCADA DNP3 Outstation and communicates to a ClearSCADA DNP3 Master via M2M 3G GSM module. The device has a number of external Digital and Analog I/Os for measuring and controlling different external environmental parameters.


  • Designed and implemented architecture and firmware for the embedded part of the biomedical Mobile X-Ray system;
  • Captured and analysed requirements for SCADA PLC at an early stage, developed a proof-of-concept prototype and proposed the overall solution architecture;
  • Ported ISaGRAF PRO Run-time Development Kit (PRDK) virtual machine and Triangle MicroWorks DNP3 Software Library to STM32 microcontroller embedded system;
  • Significantly improved quality and stability of internal embedded framework used on various projects;
  • Implemented a number of software components and drivers for the SCADA PCL controller such us M2M 3G modem, file system, networking etc.
