About
I'm an electronics engineer in Ho Chi Minh City, Vietnam, finishing an M.Eng. in electronics. I design PCBs in KiCad and do 2D CAD drafting, and I work in writing: clear questions up front, written design notes, and files you can open and check yourself.
What I can show you:
- A four-layer RP2040 board with USB-C and a 90 ohm USB differential pair, delivered as JLCPCB fabrication files (Gerbers, drill, BOM, CPL), with a 2x2 panel and a DFM check against the fab's published limits.
- A two-channel phantom-powered microphone preamp in KiCad, with the schematic checked against the TI datasheet and hand-routed inputs.
- An open-source Eagle board migrated to KiCad 10, with every net and copper segment compared against the original.
- 2D drafting delivered as DXF, DWG and PDF: a dimensioned mechanical part drawing, a 1:50 floor plan, and a scanned 1921 drawing redrawn to its printed dimensions and overlaid on the original.
Good fits: schematic capture and layout for small and medium digital/analog boards, Eagle-to-KiCad conversions, fab-ready output and DFM review, BOM cleanup, and converting sketches, scans or PDFs into clean CAD drawings.
I'm also a computer-vision engineer (Python, OpenCV, camera calibration, embedded Linux), so boards that carry cameras or sensors are familiar ground.
What I won't claim: I have not taken a product through mass production or certification (FCC/CE/UL), and I do not stamp architectural or structural drawings.
