Milestone #1 - schematic design

Yaroslav is a reliable professional. He delivered the PCB design exactly as requested, meeting both the deadline and the agreed budget. The final deliverables were technically sound and according to the instructions provided. If you have clear requirements and need someone to execute the layout and routing efficiently, he is a solid choice. Thanks for the work!

Custom ESP32-S3 Controller PCB

Yaroslav delivered a clean and well-organized 4-layer PCB design for a complex ESP32-S3 controller with LTE (BG95-M4), PoE, Ethernet, RS-485, and relay outputs. He proactively flagged component availability issues (BG95-M3 stock, ESP32 N32R8) and proposed solid alternatives. Strong technical skills, good communication, and production-ready JLCPCB files delivered on time. Will hire again.
