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
