Cao Y.

I am a hardware engineer focused on power electronics, multi‑layer PCB design, FPGA logic and STM32 embedded firmware development.

I have hands‑on experience with PFC, PSFB, Buck‑Boost and H‑bridge topologies for digital power supplies. I can deliver complete hardware solutions from schematic design, PCB layout, simulation, BOM compilation to DFM review for prototype and small‑batch products.

Main tools I use: Altium Designer, LTspice, PSpice, VHDL, STM32 MCU ecosystem.

All deliverables include native source files, BOM with manufacturer part numbers, simulation documents and hardware documentation. I strictly follow NDA requirements for confidential customer projects.
