Senior Aerospace HW & Embedded Systems Engineer | Project & Team Lead

With over 6 years of dedicated experience in the aerospace sector and dozens of successful embedded projects under my belt, I bridge the gap between high-reliability hardware engineering, firmware development, and project management. I specialize in safety-critical systems, power electronics, RF and end-to-end product development.

Available for remote freelance contracts with willingness to travel on-site for hardware integration, laboratory testing, and critical project milestones.

Core Technical Expertise & Toolset:
  • Aerospace Compliance: DO-254 (Hardware), DO-160 (Environmental/EMC) – Jet Engine Control Units, Airborne Power Distribution Systems.
  • FADEC & ECU Design: Spearheaded the conceptual architecture and hardware development of safety-critical dual-channel Electronic Control Units (ECUs / FADEC) for the Progress D-18T jet engine, powering the Antonov An-124 Ruslan – one of the world's largest and most complex heavy-transport aircraft.
  • Power Electronics: 28V DC Airborne Grids, Converters up to 3kW, HV Systems, Battery Management Systems (BMS).
  • RF & High-Speed Design: High-speed digital PCB routing, signal integrity (SI) optimization, and RF front-end design up to GHz range.
  • Embedded Systems: Firmware development in Embedded C, Bare-metal & RTOS architectures (Visual Studio, Embedded IDEs).
