Are you looking to turn a concept into a manufacturable circuit board, or do you have an old PCB that needs to be cloned and updated? With a proven track record of success, I am a Top Rated PCB Designer and Hardware Engineer with over $20k in earnings on Upwork.
What I'm doing:
✅Custom PCB Design: From Schematic Capture to PCB Layout and Routing.
✅PCB Reverse Engineering: Using high-quality images of an existing PCB, convert them back into editable Project Files (Schematic + Layout) and Gerber files.
✅EDA Software Migration: Converting designs between Eagle, KiCad, Altium, and EasyEDA.
✅BOM Management: Sourcing active components to avoid supply chain shortages (LCSC, DigiKey, Mouser).
Software Expertise:
Altium Designer | KiCad | Autodesk Eagle | EasyEDA
Why Work with Me?
✅Top Rated Expertise: Recognized for delivering high-quality work and exceptional client satisfaction.
✅Design for Manufacturing (DFM): I don't just connect dots. I design with the manufacturer's capabilities in mind (trace width, clearance, drill sizes) to ensure you don't face errors during production.
✅Reverse Engineering Precision: I meticulously trace connections to ensure the cloned board functions exactly like the original.
✅Communication: I provide regular updates and 3D renderings of the board before we finalize the files, so you know exactly what you are paying for.

I design high density, ultra compact, high-speed, RF and power PCBs in Altium or KiCad, then assemble and bring them, test up in my own lab — so you get a board that's already been powered, probed and proven, with no three-week wait on a contract assembler in between.
6+ years designing production hardware. 50+ PCB designs, 300+ boards shipped.
✅ DESIGN
Multilayer layout upto 14 layers with controlled impedance and length matching. DDR3, USB 3.1, HDMI, PCIe. Power electronics to 50A with PDN and thermal analysis. RF and antenna integration for BLE, Wi-Fi, and LoRa. Precision analog and mixed-signal partitioning. Rigid-flex. Hierarchical, documented schematics your team can actually debug.
✅BUILD
In-house SMT pick-and-place line for 1–100 unit runs. DFM audit against 100+ manufacturing rules before release. SMD Reworking and assembly facilities. BOM scrubbing for cost, lead time, and part lifecycle.
✅PROVE
Bring-up and bench validation: every rail verified, critical signals probed, thermals mapped. 500 MHz 4-channel scope, 3.2 GHz spectrum analyzer, logic analyzer, thermal camera with a fully equipped lab.
🎯You receive source files, a full manufacturing pack, and a bring-up guide your firmware team can work from on day one.
🎯Also: EMI/EMC troubleshooting on boards that failed testing, and reverse engineering of obsolete designs onto current parts.
🔧Tools: Altium Designer (primary), KiCad, EasyEDA, LTspice, SolidWorks, Onshape.
🤝Good fit if you're a startup that needs working hardware rather than a folder of Gerbers, you have a high-complexity design that punishes sloppy layout, or you have a board failing EMC and need it diagnosed properly.
I keep a daily overlap window for clients in the US, UK, and Australia — send feedback at end of day, wake up to progress.
Tell me about your board.
