Hire the Best Arduino Experts
in Nigeria

I build end-to-end IoT + automation systems: embedded firmware + sensors + edge compute (Raspberry Pi) + cloud APIs + dashboards—then I add ML/AI where it actually improves results (vision, anomaly detection, forecasting, smart alerting). If you need a system that runs reliably 24/7, logs the right data, and has a clean UI for monitoring/control, I’m your guy. What I do best Embedded + IoT + Automation Hardware + firmware on ESP32/ESP8266, Arduino, Raspberry Pi Sensors + controls: pressure, temperature, humidity, motion, current monitoring, relays, solenoids, valves, pumps, motors, etc. Protocols + comms: UART, I2C, SPI, RS485/Modbus, MQTT/HTTP, GSM/4G modules Deliverables: wiring diagrams/pinouts, clean code, robust state machines, watchdogs, retries, fault handling ML/AI for real-world devices Python ML pipelines using NumPy/Pandas/scikit-learn (and deep learning when needed) Use-cases: sensor anomaly detection, predictive maintenance, computer vision (OpenCV), classification/scoring, smart alerts Deploy models on edge devices (Raspberry Pi) with practical performance constraints Web Dashboards + APIs Backends: FastAPI / Flask / Django (REST APIs, auth, RBAC, background workers) Frontends: React / Next.js dashboards with charts, real-time updates, admin panels Databases: PostgreSQL/SQLite; event + telemetry logging, audit trails, analytics Chatbots + RAG (Retrieval-Augmented Generation) Build support/ops chatbots that can answer from your docs/knowledge base Ingestion + chunking + embeddings + vector search + guardrails Integrate into web apps, Slack/Telegram/WhatsApp-style workflows How I work I clarify requirements fast, then deliver in milestones: prototype → stable MVP → production hardening Strong focus on reliability: retries, monitoring, logs, edge-case handling, clear documentation You get a system you can actually maintain (not a fragile demo) Typical projects clients hire me for Remote monitoring/control for equipment (pumps, tanks, power systems, access control) Raspberry Pi edge gateways + sensor telemetry + dashboards ESP32 automation firmware + mobile/web control AI-assisted monitoring (vision/anomaly alerts) + web dashboard RAG chatbot for customer support or internal operations If you’re building an IoT product, automating a real-world process, or adding AI to a system that already works, message me with what you have (requirements, diagrams, repo, or photos). I’ll help you ship it cleanly.

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. Gerber files, ODB++, BOM, pick and place file, and DXF export packaged cleanly 7. PCB bring-up support, if you need help troubleshooting your first assembled boards, I'm here 8 Prototype to production handoff, I support the full journey, not just the first spin 🔒 WHAT YOU CAN EXPECT FROM ME ✔ I sign NDAs, your design stays yours ✔ I communicate daily on active projects, no radio silence ✔ I flag problems early, not at delivery ✔ I do not outsource your work to a third party ✔ I am available for long-term product development, not just one-off files ✔ Embedded systems integration? Firmware handoff? I can coordinate or connect you with the right people Send me a message with a brief description of your project, what it does, what platform you're building on, and where you are right now (idea, schematic, layout, or redesign. I respond within a few hours and I'll tell you honestly

🌟🌟🌟🌟🌟 A startup founder came to me after another engineer had spent months developing their product with little progress. They had no complete schematic, a tight enclosure, and an investor demonstration only weeks away. The challenge wasn't simply designing a PCB, it was engineering an entire hardware platform that could be manufactured with 👇👇 confidence Starting from the system architecture, I selected production ready components, developed the complete schematic, optimized a high density multilayer PCB layout, performed design for manufacturing DFM checks, generated the complete manufacturing package, and supported the prototype through fabrication. The board powered up successfully, and the client moved forward with their product demonstration. That is how I approach every project. I don't simply draw circuit boards, I engineer products that are designed to move beyond prototypes into manufacturing.
