I deeply despise engineering that only works on paper. With a PhD in Electronic and Automation Engineering, I don’t just build research experiments, I engineer robust, mass-production-ready hardware and firmware that survives the real world. If you are stuck in prototype purgatory or terrified of your next manufacturing run, I am here to get your product out of the lab and onto the factory floor. WHO I HELP Series A+ startups, ambitious SMBs, and R&D teams who need to stop iterating on breadboards and start manufacturing. WHAT I DELIVER Flawless hardware demands flawless firmware. I execute the full stack so you don't have to coordinate multiple freelancers: • Manufacturing-Ready Hardware: Custom PCB architecture, schematic capture, and layout. I don't just send you a schematic; I deliver a de-risked manufacturing package (Gerbers, resilient BOMs, DFM/DFT notes). • Bulletproof Firmware: Lean, scalable C/C++ (Bare-metal or RTOS like Zephyr/FreeRTOS) deployed on STM32, ESP32, and Nordic MCUs. • Secure Edge Connectivity: Stable RF telemetry (LoRaWAN, BLE, WiFi, Cellular NB-IoT) optimized for extreme low-power budgets. • Industrial Automation & Control: Complex motor control, analog sensor integration, and custom automated test fixtures (Python/LabVIEW) to ensure 100% production yield. MY UNFAIR ADVANTAGE • Zero Finger-Pointing: Because I design the board AND write the embedded code, there is no blame game between the hardware and software guys. I own the system architecture from end to end. • Total IP Ownership & NDA-Ready: You receive full ownership of the schematics, code repositories, and test scripts from day one. I operate under strict confidentiality, send over the NDA and let's get to work. • Documentation-First Factory Handoff: I don't just throw ZIP files over the wall. You get comprehensive architecture docs, build instructions, and direct manufacturing handoff support so your Contract Manufacturer (CM) knows exactly how to build and test your product. LET'S BUILD IT Stop wrestling with designs that won't scale. Message me with your core requirements (MCU preferences, power/enclosure constraints, target certs, and quantities) and let's map out your roadmap to production.

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.

I help medical and IoT product teams design the right hardware architecture early, so they avoid costly PCB re-spins, noise issues, and late-stage failures. If you’re building a sensor-heavy, STM32-based, or medical-adjacent product, I act as your hardware systems architect—focusing on design decisions, trade-offs, and long-term reliability, not just execution. How I typically help: • System architecture & feasibility studies • Component and topology selection (MCU, sensors, AFE, power) • Schematic-level hardware design & review • Pre-fabrication PCB audits to reduce redesign risk My work is decision-driven and outcome-focused. I start by understanding what you are building and why, then provide clear, documented recommendations you can confidently execute or manufacture. I’ve worked on medical electronics, bio signal front ends (ECG/EMG), wearables, and IoT devices, where design mistakes are expensive and timelines matter. If you’re looking for clarity, strong architecture, and fewer hardware surprises, I’d be glad to help. ✅ Core Expertise 🔹 Hardware Product Development - Architecture Design, Schematic & Layout (up to 12-layer PCBs) - Rigid, Rigid-Flex & Flex PCB Design - Signal & Power Integrity, EMI/EMC mitigation - DFM/DFT, FMEA, Risk Analysis, Certification Prep - BOM optimization, part lifecycle, obsolescence management 🔹 Sensor-Integrated Wearables & IoT - Real-time biometric sensing (ECG, EMG, HR, SpO2, Temp, IMU) - Wireless: BLE, Wi-Fi, LoRa, 4G, CAN, RS485 - Medical-grade signal acquisition & conditioning - Battery management, power efficiency & charging circuits 🔹 Prototyping & Compliance - Pre-compliance testing: EMI/EMC, Thermal, Vibration - Regulatory: Medical safety (IEC standards), ISO/NABL - Detailed documentation: test plans, architecture diagrams, handover packages 🔹 Tools & Platforms - ECAD: Altium Designer, OrCAD, CAM350, KiCAD - Firmware Platforms: STM32, Nordic nRF52, ESP32/8266, Microchip, Raspberry Pi - Protocols: I2C, UART, SPI, RS232/RS485, LVDS, RF, NFC ✅ Deliverables - Design Concept Block Diagrams - Process Flow Block Diagrams - Schematic PDF - Design Files (Schematic & Layout) - Fabrication Files - Assembly Files - Bill of Materials - 3D Models - Components Library - Test Documents (If req.) 🏆 Notable Projects & Solutions Built - Smart Drug Delivery Device: Precision-controlled insulin injector - Bone Density Meter: Early-diagnosis medical scanner - Julia Robot: Cooking automation system with embedded sensors - EMG Wearable: Portable diagnostic device for muscle activity monitoring - SOWBIT: Veterinary health monitor (ECG, SpO2, Temp) for livestock - Smart Ring: Measures multiple vitals via fingertip contact - Elite Alerte: Maritime emergency alert & sensing system - CloudSwitch: IoT-enabled wireless AC meter for remote energy tracking - Fuel Level Sensor (Ultrasonic + GSM): Real-time monitoring for containers - PoE Switch & Weighing Scale: Industrial-grade, high-precision electronics 🌍 Why Clients Choose Me ✅ Medical-grade design focus with regulatory foresight ✅ Deep cross-industry experience from wearables to industrial controls ✅ Excellent communication, proactive updates, and engineering documentation ✅ Efficient collaboration with global clients and vendors ✅ Quality-first mindset with long-term reliability and support
