Industrial PCB Designer (ESP32-S3, 24V Power, EMI/EMC, IP65 Enclosure) – IoT Pulse Controller for Car Wash/Vacuum

Tetiana did an excellent job on the PCB design for our ESP32-S3 IoT pulse controller. She understood the 24V power, industrial reliability, EMI/EMC, and IP65 enclosure requirements very well. Communication was clear, the work was professional, and she delivered earlier than expected. I am very satisfied and would gladly work with her again.
