WHAT I DO 𝗣𝗖𝗕 / 𝗘𝗹𝗲𝗰𝘁𝗿𝗼𝗻𝗶𝗰 𝗘𝗻𝗴𝗶𝗻𝗲𝗲𝗿𝗶𝗻𝗴 End-to-end hardware for connected consumer and commercial devices WiFi/BLE sensors, smart switches, environmental monitors, battery-powered trackers. I handle antenna keepout and module placement correctly the first time, design for FCC Part 15B compliance, and build boards that pass DRC and upload to JLCPCB's SMT assembly flow with zero unmatched parts. 𝗜𝗻𝗱𝘂𝘀𝘁𝗿𝗶𝗮𝗹 & 𝗘𝗺𝗯𝗲𝗱𝗱𝗲𝗱 𝗖𝗶𝗿𝗰𝘂𝗶𝘁 𝗗𝗲𝘀𝗶𝗴𝗻 Motor control (BLDC, brushed DC via MOSFET/H-bridge), power electronics (buck/boost/flyback, LDO regulation), high-resolution ADC/DAC interfacing, RS485/Modbus/CAN communication, and sensor integration (analog, I2C, SPI). I design for real operating environments, not just the bench. 𝗦𝗰𝗵𝗲𝗺𝗮𝘁𝗶𝗰 & 𝗕𝗢𝗠 𝗥𝗲𝘃𝗶𝗲𝘄 / 𝗗𝗙𝗠 𝗔𝘂𝗱𝗶𝘁𝘀 Independent, evidence-based peer review of existing designs validating findings against schematics, datasheets, and calculations, flagging single-source parts, and delivering a clear GO / conditional-GO / NO-GO recommendation with reference-designator-level citations. 𝗣𝗿𝗼𝗱𝘂𝗰𝘁𝗶𝗼𝗻-𝗥𝗲𝗮𝗱𝘆 𝗟𝗮𝘆𝗼𝘂𝘁 & 𝗠𝗮𝗻𝘂𝗳𝗮𝗰𝘁𝘂𝗿𝗶𝗻𝗴 𝗦𝘂𝗽𝗽𝗼𝗿𝘁 Full deliverable packages: schematic (PDF + native source), PCB layout, Gerbers (RS-274X), BOM with verified LCSC/DigiKey/Mouser part numbers, pick-and-place files, 3D render/STEP export, and assembly drawings. I design around real DFM constraints — 0402/0603 minimums, no BGA or hand-soldered parts when the job calls for full SMT assembly, and I flag stock/availability risk on every BOM line before it becomes your problem. 𝟯𝗗 𝗖𝗔𝗗 & 𝗠𝗲𝗰𝗵𝗮𝗻𝗶𝗰𝗮𝗹 𝗗𝗲𝘀𝗶𝗴𝗻 Full mechanical design and 3D modeling in SolidWorks, including enclosures and housings built to fit the electronics I design, mechanical tolerancing, mesh repair, and watertight geometry cleanup for 3D printing. I prepare STL files for prototyping and coordinate STEP exports between electrical and mechanical teams. Because I design both the PCB and its enclosure, I catch fit, clearance, and thermal issues at the design stage instead of after the first prototype comes back wrong something that happens often when electrical and mechanical design are handled by two separate people who never see each other's files. 𝙃𝙊𝙒 𝙄 𝙒𝙊𝙍𝙆 1. Requirements & block diagram — I confirm fixed pin assignments, power architecture, mechanical constraints, and connector choices before touching a schematic, so firmware, hardware, and enclosure stay in sync. 2. Schematic design — calculated, not copied. 3. Layout & mechanical design — placement, routing, and enclosure fit designed together, not after the fact. 4. Production data — Gerbers, BOM, CPL, STEP files, and assembly drawings. 5. Design notes — thermal behavior, current limits, mechanical fit, and part substitutions. TOOLS 𝗞𝗶𝗖𝗮𝗱, 𝗔𝗹𝘁𝗶𝘂𝗺 𝗗𝗲𝘀𝗶𝗴𝗻𝗲𝗿, 𝗘𝗮𝘀𝘆𝗘𝗗𝗔 𝘀𝗰𝗵𝗲𝗺𝗮𝘁𝗶𝗰 𝗰𝗮𝗽𝘁𝘂𝗿𝗲, 𝗣𝗖𝗕 𝗹𝗮𝘆𝗼𝘂𝘁, 𝗮𝗻𝗱 𝗹𝗶𝗯𝗿𝗮𝗿𝘆/𝗳𝗼𝗼𝘁𝗽𝗿𝗶𝗻𝘁 𝗰𝗿𝗲𝗮𝘁𝗶𝗼𝗻. 𝗦𝗼𝗹𝗶𝗱𝗪𝗼𝗿𝗸𝘀 𝗳𝗼𝗿 𝟯𝗗 𝗖𝗔𝗗, 𝗺𝗲𝗰𝗵𝗮𝗻𝗶𝗰𝗮𝗹 𝗱𝗲𝘀𝗶𝗴𝗻, 𝗮𝗻𝗱 𝗲𝗻𝗰𝗹𝗼𝘀𝘂𝗿𝗲 𝗺𝗼𝗱𝗲𝗹𝗶𝗻𝗴. WHY WORK WITH ME I write clear, specific proposals, flag problems before they become expensive including mechanical clearance issues, not just electrical ones and communicate plainly about tradeoffs so you can make the call, not guess at mine. If your project needs an ESP32/STM32 product from breadboard to production, a mechanical enclosure or 3D model to go with your electronics, or an honest second set of eyes before manufacturing, send me the specs.
