A startup founder came to me with a four-week investor deadline, a constrained enclosure, and no schematics. We engineered a dense 6-layer IoT PCB layout with full signal integrity simulation it powered up perfectly on the first pass, secured their seed round, and earned this review: “He didn’t just design a circuit board, he literally saved our investor launch.” That outcome isn't luck. It's the result of treating every hardware engagement as a production problem from day one, not a prototype exercise. I'm a Top Rated Plus PCB design engineer and electrical engineering specialist with 10+ years of experience and 85+ completed hardware deployments across IoT devices, industrial automation, robotics platforms, and medical device electronics. My work covers the full hardware development cycle, schematic design, multilayer PCB layout, embedded systems integration, signal integrity optimization, and manufacturing-ready deliverables that hold up through fabrication and real-world operation. Recent projects include a flexible PCB design for NIR (near-infrared) sensing and a Bluetooth lapel microphone board built on the Nordic NRF52840 compact, signal-sensitive hardware where PCB layout discipline, impedance control, and RF interference management directly determine whether the product works. ESP32 and STM32 embedded systems, BLE and WiFi communication hardware, motor controllers, and power electronics for EV and industrial automation applications make up the rest of my active project history. ● How I Work: I design primarily in Altium Designer and KiCad, with schematic design and IPC-compliant component sourcing completed before layout begins. Every PCB layout is built around DFM and DFA principles, high-speed routing, impedance control, EMI/EMC mitigation, differential pair routing, and thermal management so respins stay rare and first-pass success rates stay high. Deliverables include fabrication-ready Gerber files (RS-274X/ODB++), CPL/pick-and-place files, and production-ready Bills of Materials. No loose ends at handoff. ● Core Expertise: ⁃ PCB Design & Layout: Multilayer PCB layout (2-layer to 12+ layer), high-speed routing, signal integrity analysis, impedance matching, EMI/EMC mitigation, rigid-flex PCB design, thermal management, DFM/DFA optimization ⁃ Schematic Design & Circuit Engineering: Schematic capture, analog and digital circuit design, mixed-signal circuit development, power electronics design, BOM optimization, component lifecycle analysis ⁃ Embedded Systems & IoT Hardware: ESP32, STM32, ARM Cortex embedded hardware development, BLE and WiFi system integration, low-power IoT hardware design, embedded firmware-ready platform development, wireless sensor node design ⁃ ECAD Tools: Altium Designer, KiCad, Autodesk Eagle footprint and library generation to IPC standards ⁃ Manufacturing Deliverables: Gerber files (RS-274X / ODB++), pick-and-place/CPL files, production BOM, fabrication, and assembly documentation. ● Who I Work With: My strongest engagements are with founders and engineering teams who treat hardware development as a serious investment not a race to the cheapest PCB layout quote. ● Who are strong fit: ⁃ You are building a market-bound product and understand the real costs of component sourcing and PCB prototyping cycles ⁃ You are ready to invest the time and budget that production-quality electrical engineering actually requires ⁃ You come with defined requirements a clear concept, target specs, or reference schematic design ⁃ You are available for brief milestone reviews to keep the PCB design aligned throughout development ● We are not a fit if: ⁃ You need a homework assignment or university thesis completed. I work exclusively on commercial hardware ⁃ You want to skip signal integrity checks or DFM rules to reduce cost, but still expect a reliable, production-ready board ⁃ You need a complex multilayer PCB design completed in two to three days responsible embedded systems engineering requires a realistic timeline ● Track Record: 100% Job Success · Top Rated Plus · $200K+ earned · 5,700+ hours delivered Upwork hourly and fixed-price engagements, from initial schematic design through manufacturing handoff. If your project is production-bound and you need a PCB design and embedded systems engineer who takes full ownership from schematic design through fabrication-ready deliverables invite me to your job or book a direct consultation to review PCB stack-up strategy, circuit architecture, and component selection before we begin.
