Hire the Best Circuit Designers

I help companies design, prototype, and troubleshoot complex hardware systems, especially where mechanical, electrical, thermal, and control systems must work together reliably in demanding real-world environments. I am a former Head of R&D at Northrop Grumman Marine Systems, with experience in turbines, generators, electric motors, rotating machinery, and large-scale power systems. My work also includes combustion systems, battery systems, power electronics, embedded hardware, and full product development from concept through working prototype. I work with startups and established companies on: - hardware system design - rotating machinery and power systems - combustion, thermal, and fluid systems - battery and embedded hardware - controls, instrumentation, and industrial automation - diagnosing and solving difficult engineering problems I focus on practical, buildable solutions with strong attention to reliability, manufacturability, safety, and system integration. I’m often brought in when a project needs senior-level engineering direction to move from concept to a working system efficiently. I studied engineering and business at Stanford University and have 20+ years of experience working with venture-backed startups, helping connect engineering decisions to product development, scaling, and execution.

Are you looking for a freelancer creating accurate and reliable 🔴 Circuits schematics, layouts, and simulations as well as 3D CAD models 🔴? As a mechatronic engineer, I have an electrical and mechanical engineering background. I am introducing myself and my services as a freelancer in the field of electronic circuits and PCB design. Being a mechatronic engineer helps me to integrate both electrical and mechanical considerations into my designs, and that's what sets me apart from other designers. My expertise lies in using: • Autodesk Eagle • Altium designer • EasyEDA • KiCad • Proteus To generate accurate and reliable: • Schematics • PCB layout design • 3D models And I will provide you with: • Detailed PDF files • Images • DXF files • Bill of Materials (BOM) That clearly illustrates the design and its components, and this will not only help you to understand the design better but also allow for quick and efficient manufacturing processes. I can help you design your ⚫ 3D model enclosure ⚫ for your PCB or consider this aspect while designing the PCB itself. This results in a more integrated and optimized solution that meets both your electrical and mechanical requirements. As a new freelancer on Upwork, I am eager to take on any job at the 🔴 most reasonable cost 🔴 to grow on this platform and receive valuable feedback. I am committed to building long-term relationships with my clients by prioritizing clear communication, timely delivery, and customer satisfaction. I am open to feedback and willing to make adjustments to ensure complete satisfaction with my work. I am eager to establish a lasting partnership. If you are looking for a reliable freelancer in the field of electronic circuits and PCB design, I would be honored to work with you. Please don't hesitate to contact me to discuss your project in more detail and to receive a personalized quote.

I’m a PCB design | Reverse PCB Design Engineer specializing in reconstructing, analyzing, and improving existing circuit boards when original documentation is missing or incomplete. Over the past 10+ years, I’ve reverse-engineered dozens of commercial products ranging from consumer electronics to industrial controllers helping clients recreate legacy hardware, correct design flaws, and prepare boards for manufacturing. Work History & Experience •Rebuilt complete schematic and PCB files from physical boards for multiple clients in the U.S. and Europe •Successfully reverse-engineered 4-layer and 6-layer RF boards, including WiFi, Bluetooth, and GPS modules •Restored obsolete industrial control boards where BOM and Gerbers were no longer available •Converted entire product families from old proprietary boards into modern Altium or KiCad designs •Helped several startups recover and redesign hardware after losing original engineering teams •Reverse-designed battery-powered IoT devices, optimizing power paths, charging circuits, and safety features •Translated raw PCB scans and photos into fully manufacturable Gerber and ODB++ files •Conducted board validation, corrected routing issues, and improved manufacturability for mass production •Supported clients in factory communication, DFM review, stack-up selection, and production testing Core Skills •PCB reverse engineering (from 1-layer to 8-layer boards) •Schematic reconstruction from physical PCB •Net tracing, component identification, and footprint rebuilding •Recreating BOM with equivalent components •Altium, KiCad, Eagle, OrCAD •High-speed and RF routing reconstruction •Power supply and charger circuit analysis •Legacy hardware modernization •EMC/ESD improvement and reliability upgrades •Gerber recreation for manufacturing What I Can Deliver •Complete schematic + PCB files from any board •Clean, readable, and logically organized circuits •Rebuilt BOM with part numbers and sourcing links •Improved design ready for prototyping or mass production •DXF/STEP data for enclosure designers •Manufacturing package (Gerber, drill, pick-and-place, PDF docs) Why Clients Choose Me •Hands-on experience with 100+ boards across multiple industries •Ability to reverse-engineer boards without original documents •Fast, precise reconstruction—even for dense multilayer layouts •Professional communication and clear reporting •A strong record supporting real production builds

I design and develop embedded electronic devices, working across hardware and firmware from initial design to production-ready systems. I work end-to-end: from schematics and KiCad PCB layout to firmware bring-up, debugging, validation, and preparation for manufacturing. Platforms & systems: • ESP32, STM32, nRF52 • C / C++, ESP-IDF, FreeRTOS, Zephyr, bare-metal Wireless & device protocols: • Wi-Fi, Bluetooth LE, Thread, Matter / HomeKit • Sub-GHz RF (433 / 315 MHz), infrared Hardware & production: • Multilayer PCB design in KiCad (fab-ready files, realistic BOMs) • Hardware bring-up, debugging, and validation • Preparing designs for manufacturing and real-world use Mechanical & product design: • Functional enclosure and mechanical part design (Fusion 360) • Design for 3D printing and rapid prototyping • Mechanical integration of electronics into real products Why work with me: • Production-first mindset — not just working prototypes • Strong understanding of hardware–firmware interaction • Clear communication and realistic timelines If you’re building a device and need an engineer who can turn it into a reliable, production-ready product — let’s talk.

Running a temporary lower billing rate as I launch on this platform. Hi, I’m am an American U.S. based medical device engineer with 15+ years of experience designing, testing, and validating PCB-level electronics for medical, industrial, military, and R&D applications. I specialize in EagleCAD/Fusion360 (primary) and Altium-compatible designs, and have hands-on experience with micro-soldering and bench-level troubleshooting and repair (facilities can be arranged for the right project). If you need help turning a schematic into a manufacturable board, debugging an existing design, or setting up automated testing for your hardware, I can support you from system concept through prototype, verification, and market release. Transparent communication and regulatory-grade documentation come standard—you’ll always know what’s been done, what’s next, and why it matters. Let’s get your design validated and ready to build.
