Hire the Best Circuit Designers
in Nigeria

PCB Design Engineer | Altium Designer | KiCad | Circuit Design | 3D CAD | Hardware Prototyping I turn circuit ideas into real, manufacturable hardware. Whether you have a rough schematic on a napkin or a fully validated design ready for layout, I build PCBs that work the first time clean, reliable, and ready for production. What I Deliver: → PCB Layout & Design — single to multilayer boards, high-speed digital routing, controlled impedance, RF layouts, power electronics. I work in Altium Designer and KiCad, delivering Gerbers, drill files, assembly drawings, and full documentation your fab house can use immediately. → Circuit Design & Simulation — analog frontends, sensor interfaces, DC-DC converters (buck, boost, flyback), motor drivers, amplifier stages, mixed-signal systems. I size components for real-world conditions, not just ideal simulations. → 3D CAD & Mechanical Integration — SolidWorks modeling for enclosure fit checks, thermal planning, connector placement, and board-to-mechanical coordination. No surprises when the PCB meets the case. → Prototyping & Manufacturing Support — BOM optimization for cost and availability, supplier sourcing across JLCPCB, DigiKey, and Mouser, DFM/DFA review, and assembly file generation. I have built and shipped boards for IoT sensors, motor controllers, RF frontends, and consumer electronics. Recent Work: 4-Layer IoT Sensor Node — BLE 5.0, LiPo charging with fuel gauge, ultra-low power sleep modes ), environmental sensors. Passed EMC pre-compliance testing. BLDC Motor Driver — 24V/10A, integrated current sensing with shunt amplifiers, gate drivers, and overcurrent protection. Designed for continuous industrial operation. RF Frontend Board — impedance matched microstrip traces, LNA and PA stages, bandpass filter, SMA connectors. Characterized with VNA, met S11 15dB across target band. Tools I Use: Altium Designer · KiCad · SolidWorks · Circuit Design · Embedded C · STM32 · ESP32 · nRF52 Why Work With Me: → Real hardware, not just pretty layouts. I prototype what I design. I know which footprints actually solder well, which thermal vias matter, and where your assembly house will push back. → Fast without reckless. I deliver initial layouts in 2–3 days for standard boards, 5–7 days for complex multilayer designs. No missed deadlines, no ghosting. → DFM first thinking. Every design I ship is reviewed for manufacturability before it hits your inbox. Fewer respins, lower costs, faster time to market. → Clear communication. You get progress updates, design decisions explained, and direct answers. No jargon walls, no hiding behind complexity. → Nigerian hustle, global standards. I compete on quality and speed, not just rate. My clients come back because the boards work. Ready to build something? Send me your schematic, your block diagram, or even just your idea. I will review it within 24 hours and tell you exactly what it takes to turn it into a real PCB, timeline, cost, and any risks I see upfront. Let's make hardware that ships.

PCB Designer & Hardware Engineer | Altium Designer · KiCad Desgner · OrCAD | Medical PCB Design| Medical PCB Design | IoT, Automotive, Aerospace | PCB Design | PCB Design Circuit Design | PCB Design esp32 | Electrical Engineer | PCB Layout | Eagle Esp32 | PCB Power Electronics | High Speed PCB | Gerber Files | Multilayer PCB Design | High Speed Boards, Circuit Design Expert | DFM | Electronic Engineer Your hardware idea deserves more than a pile of Gerber files and a goodbye email. Most clients come to me after a bad experience, a freelancer who disappeared mid project, delivered boards that failed DFM review, or handed over a schematic that no manufacturer could read, I built my entire process around making sure that never happens to you. I am an electronics engineer PCB Designer specializing in PCB design | PCB Firmware | PCB Layout and PCB circuit design taking projects from a rough concept or napkin sketch all the way to a production ready board you can confidently hand to JLCPCB, PCBWay, OSHPark, or any other fab and get back exactly what you designed. WHY CLIENTS KEEP COMING BACK: I don't just hand you a .zip file. Every project I deliver includes: ✔ A complete schematic capture that is clean, annotated, and easy to revisit ✔ PCB layout optimized for signal integrity, thermal management, and EMC/EMI compliance ✔ Full DFM, Design for Manufacturing and DFA (Design for Assembly) review baked in not added as an afterthought ✔ Production ready Gerber files, ODB++ files, pick and place file, BOM (bill of materials), and DXF export ✔ A 3D PCB Design model so you can visualize the final board and check mechanical fit before ordering ✔ Clear documentation so your factory, assembler, or next engineer can pick up exactly where we left off If your board comes back with a fabrication issue, I fix it at no cost if the error is not from your end or the manufacturer. SOFTWARE I WORK WITH ARE: Altium Designer | KiCad | EasyEDA | Eagle CAD | Cadence Allegro | OrCAD | Proteus | LTspice Whether you have an existing project in Altium Designer And PCB Designer and need a layout revision, or you're starting from scratch in KiCad or EasyEDA, I work in your environment — not the other way around. MICROCONTROLLERS & PLATFORMS I DESIGN AROUND ESP32 · ESP8266 · STM32 · Arduino / ATmega328P · Raspberry Pi (CM3/CM4) · Nordic BLE / NRF52840 · PIC32 If your project is built around one of these or something not on this list, I've almost certainly designed around it before. I understand the routing constraints, power requirements, and RF keep out rules each platform demands. WHAT I BUILD I specialize in boards that go into the real world, not just proof of concept demos: → IoT devices — Wi-Fi, Bluetooth, BLE device, LoRa PCB, Zigbee, GPS integrated → Wearable PCB design — compact, battery-powered, tight form factor → Motor controller PCB — brushless DC, stepper, servo, H bridge → Power supply PCB & battery management system (BMS) — SMPS, LDO, USB-C PD → Solar charge controller PCB — MPPT, PWM, off-grid power systems → Medical device PCB — IEC 60601-aware layouts, low-noise analog front ends → Industrial automation PCB — sensor interfaces, PLCs, relay drivers → LED driver PCB — constant current, dimmable, high power arrays → Audio PCB — preamps, DACs, signal conditioning, low noise analog design → PCB reverse engineering — I can reconstruct full schematics and layout from a physical board or clear photographs, with no original design files needed MY PROCESS (so you always know where things stand) 1. Discovery, I ask the right questions upfront so nothing surfaces mid project 2. Schematic design from scratch or review of your existing schematic 3. Component selection and BOM optimization for availability and cost 4. PCB layout with DFM or DFA built in at every step 5. PCB Design rule check, electrical rules check, and 3D clearance review 6.
