As a Top-rated Upwork freelancer and experienced Hardware Engineer, I thrive on designing and developing complete electronic systems that solve real-world engineering challenges. My work blends deep technical expertise in PCB design, RF engineering, and embedded systems with a strong focus on building production-ready, reliable, and scalable hardware products. Over the years, I’ve worked across the full hardware development cycle — from concept, schematic design, and PCB layout to firmware development, prototyping, RF optimization, and manufacturing support. I enjoy turning complex ideas into functional, manufacturable electronic systems that perform reliably in real environments. Here's a snapshot of the domains I've mastered: Hardware Specialties 💻🔌 ✅ Embedded Systems Development: Expert in designing embedded solutions using ESP32, STM32, PIC, Arduino, and Raspberry Pi (including CM4/CM5 platforms). I handle everything from low-level firmware (C/C++) to hardware integration, real-time control systems, and IoT-enabled devices. ✅ PCB Design & Hardware Engineering: Advanced experience in schematic design, multilayer PCB layout (2–16 layers), high-speed routing, power distribution, signal integrity, and EMI/EMC-aware design. I focus on turning circuits into robust, production-ready boards. ✅ RF & Microwave Engineering: Specialized in RF circuit design, antenna development, and electromagnetic simulation using CST, HFSS, ADS, and 4NEC2. My work includes LoRa, GPS, RFID, wireless communication systems, and RF optimization for real-world performance. ✅ Wireless & IoT Systems: Designing connected systems using Bluetooth, WiFi, LoRa, and custom RF protocols. I develop IoT devices for automation, monitoring, sensing, and smart control applications. ✅ Sensor & Embedded Integration: Experience with MEMS/IMU, GPS modules, RFID systems, displays, motor drivers, and industrial sensors for data acquisition and intelligent control systems. Design Tools 🧰 Altium Designer | KiCad | EasyEDA | CST Studio Suite | HFSS | ADS | MATLAB & Simulink | LTspice | NI Multisim | Proteus | 4NEC2 Project Experience 🚀 ✔ Raspberry Pi CM4/CM5 Carrier Board Development ✔ High-speed Multilayer PCB Design for complex systems ✔ ESP32, STM32 & Arduino-based embedded products ✔ RF & Antenna Design for LoRa, GPS, and RFID systems ✔ IoT & Wireless Communication Devices ✔ Motor Control & Automation Systems ✔ Power Electronics & DC-DC Converter Designs ✔ Custom Sensor-based Data Acquisition Systems ✔ Smart Home & Industrial Automation Solutions ✔ Prototype development to manufacturing-ready hardware My approach is centered around engineering precision, manufacturability, and system-level reliability. Whether it’s a small embedded controller or a complex RF-enabled multi-layer system, I ensure every design is optimized for performance, stability, and real-world deployment. I also support full product development — from initial architecture and schematic design to firmware, debugging, testing, and production assistance. I’m always excited to collaborate on innovative hardware ideas and help transform concepts into fully functional electronic products ready for manufacturing and deployment.
