Valentin Stoyanov

Embedded Software Engineer at Fontys ICT - HTES (2025-02 – 2025-07)

Architected a hybrid braking system for an autonomous vehicle to enable precise, closed-loop deceleration control.
Designed a dual-loop cascaded PID controller using direct force feedback (0-1000N) from a load cell to ensure repeatable braking performance.
Developed a high-fidelity MATLAB/Simulink model of the electromechanical braking system to simulate and validate control strategies.
Analyzed the Simulink model to identify and document the limitations of a fixed-gain PID controller when handling system non-linearities.
Authored a complete engineering documentation suite, including requirements analysis, design specifications, and a final project handover plan.

Software Engineer at DHR Engineering (2022-07 – 2024-07)

Developed and maintained software services for a robotic automation system within a 3D printing farm, enabling a 73.8% increase in machine utilization over a 24-hour period compared to manual operation.
Collaborated with an external client to design and implement a safety system for their DVF (5-axis machining center), machine, protecting operators from two KUKA robot arms.
Reverse-engineered the communication protocols for Bambu Lab 3D printers, utilizing FTP for file transfers and MQTT for command and control, which enabled full remote operation and status monitoring.
Architected and developed the central orchestrator service for a robotic automation system, enabling real-time communication between a ROS 2-based robotic arm and the 3D printing farm via Python and MQTT.

Embedded Software Engineer at Hyster-Yale Group (2022-02 – 2022-07)
