Senior Embedded Hardware Architect & Firmware Engineer | PCB Design & End-to-End Product Development | EMI/EMC & Product Compliance | NPI &Technical Leadership I help businesses turn electronic product concepts into working, testable, and manufacturable products. With 12+ years of embedded hardware engineering experience, I specialize in hardware architecture, schematic design, multilayer PCB development, component selection, power management, prototype bring-up, hardware debugging, validation, and manufacturing support. My primary specialization is embedded hardware engineering. I also provide embedded firmware development and hardware–firmware integration when projects require a broader engineering solution. What I Can Help You Build 1. Embedded Hardware & PCB Design** - Hardware architecture and circuit design - Schematic development and multilayer PCB design - Component selection, BOM optimization, and design reviews - Analog, digital, and mixed-signal electronics - Power supplies, battery-powered systems, and power management - High-speed digital interfaces and PCB design support 2. Hardware Debugging & Design Improvement** - Prototype bring-up and circuit troubleshooting - Power, sensor-interface, and communication problems - Root-cause analysis and corrective design changes - Hardware verification, validation, and design optimization - DFM/DFMA and manufacturing-related improvements 3. Embedded Product Development** - MCU-based electronic systems - Sensor integration and communication interfaces - BLE-connected and IoT products - Battery charging, protection, and monitoring - Embedded firmware and hardware–firmware integration - Prototype development and engineering handover 4. Product Integration & Manufacturing Support** - Coordination across hardware, firmware, and mechanical engineering - Prototype fabrication and assembly coordination - PCB manufacturing and EMS coordination - Design documentation and production support - Engineering support for applicable EMI/EMC and product-compliance activities Relevant Product Experience My engineering background includes wearable electronics, Bluetooth hearing aids and charging accessories, IoT data-acquisition gateways, EV electronics, industrial instrumentation, fuel dispenser controllers, and connected embedded products. One example is a wearable health-monitoring smart band for SpO₂, heart rate, skin temperature, and ECG data, incorporating a Nordic Semiconductor-based platform, BLE connectivity, battery management, wireless-charging integration, and a four-layer rigid-flex PCB. I contributed across hardware, firmware, sensor integration, debugging, mechanical integration, and prototype validation. I have also worked on products involving multilayer and rigid-flex PCB design, embedded processors and DSPs, battery-powered electronics, industrial communication interfaces, and manufacturing support. How I Work I begin by understanding your requirements, existing design, constraints, and expected deliverables. I then help define the engineering approach, identify technical risks, execute the agreed work, and validate the implementation against the available requirements. I can take on a clearly defined task—such as schematic design, PCB development, or hardware debugging—or contribute to a broader product-development project. Where necessary, I can coordinate specialist support for selected firmware, mechanical, prototyping, or manufacturing activities, with responsibilities agreed in advance. If you are developing a new electronic product, improving an existing design, or troubleshooting a prototype, share your requirements and current development stage. We can identify the technical scope, deliverables, and next steps.
