About me
Electronics engineer focused on practical PCB design, hardware integration, enclosure fit. I turn schematics into fabrication-ready boards that pass DFM checks without revision loops. Core skills: • multi-layer PCB layout • high-speed routing • ESP32, BLE integration • DFM compliance • 3D CAD enclosure fit • BOM optimization. I use KiCad, Altium, Onshape daily.
