Relevant Coursework

Work Experience

Electronic Engineer Mar 2025 – Present
ELKE, SmartShoe: Gait Monitoring and Analysis System Patras, Greece
  • Conducted classification and performance benchmarking of FSR-based pressure sensor insoles, providing insight on system architecture decisions.
  • Designed and developed PCBs for an ESP32-based system-on-module carrier board, integrating sensor interfaces and battery management, covering schematic capture, component selection, and layout optimisation for manufacturability and size constraints.
  • Managed over 50% reduction in board footprint through routing and layout optimisation.
  • Worked closely with firmware engineers to define sensor sampling strategies, enabling reliable low-power data acquisition and Bluetooth transmission, achieving over 30 days of continuous module operation on a single charge.

Projects
