About
Do you need a reliable Embedded Systems Engineer who can design your hardware, firmware, and PCB layouts from scratch and deliver a working prototype faster than expected?
That’s exactly what I do.
I help startups, researchers, and product teams bring their ideas to life by designing custom IoT devices, sensor systems, and embedded electronics from the initial schematic all the way to a fully functional PCB with firmware ready for testing and deployment.
As a freelance embedded systems and PCB design engineer, I provide IoT hardware development and firmware integration services using ESP32, STM32, and Arduino platforms.
My focus is always on reliability, manufacturability, and speed. Whether it’s a wearable medical sensor, an industrial IoT module, or a custom research prototype, I ensure each design is optimized for performance, safety, and long-term scalability.
I’m passionate about bridging the gap between concept and creation.
Every circuit I design and every line of code I write aims to make your idea smarter, faster, and ready for the real world.
If you’re looking for a dependable engineer who treats your project like his own let’s connect and build something that lasts.

Featured Projects
Custom FPGA TENEP Board For Aerospace Application
A high-performance, Tenep board engineered for aerospace systems requiring precise control, high-speed data processing, and real-time reliability. Designed with robust power management, EMI/EMC protection, and fault-tolerant architecture.
ESP32 Based Wireless Sensor Cart
This board was built for real-time wireless data transmission, combining robust hardware design with power efficiency and expandability.Designed with a battery management system and added 4-channel relay outputs to control external wheels and actuators
Custom AQI & CO2 Monitoring Sensor with STM32
This project showcases expertise in miniaturized PCB design, sensor integration, and IoT-ready wireless communication.Designed for portable and wearable environmental sensing applicationsOptimized for low power consumption in a compact form factor
Electromyography (EMG) Signal Acquisition Circuit
Design and developed a complete circuit and PCB for an Electromyography (EMG) system. The objective was to accurately acquire and amplify the weak myoelectric signals produced by muscle contractions while effectively filtering out noise and other artifacts. This required a careful approach to analog and mixed-signal design to ensure a clean, usable output signal for further analysis or control applications. .
IoT-Enabled Adjustable Electric Nerve Stimulator with Mobile App
This capstone project showcases my full-stack capabilities in creating a connected medical device: an adjustable electric nerve stimulator designed for carpal tunnel syndrome treatment. It encompasses embedded systems design, PCB development, and mobile application development for a complete user experience.
Custom Reed Switch for Orange Pi
A compact magnetic reed switch sensor designed for reliable door open/close detection with Orange Pi boards. It offers simple GPIO interfacing, low power consumption, and high durability ideal for smart home automation, security systems, and access monitoring applications.
