Embedded Systems Engineer | End-to-End Firmware & Hardware Prototyping
I am an experienced Embedded Systems Engineer specializing in device communication, data processing, and efficient system design. With expertise across the entire embedded development lifecycle, I provide clients with end-to-end solutions—delivering both embedded software and functional hardware prototypes from a single source.
My technical foundation is rooted in C/C++, Python, and C#, along with extensive experience developing firmware for ESP32, ARM, STM32, and Silicon Labs platforms. I work with both bare-metal systems and embedded operating systems such as FreeRTOS or Linux, ensuring flexibility and scalability across applications.
Beyond firmware, I design custom hardware prototypes, including PCB design (schematic and layout) using KiCad and Fusion Electronics, sensor integration, motor control, and wireless communication systems. This unique combination of software and hardware expertise allows me to streamline development, reduce turnaround time, and ensure seamless integration between components.
I place a strong emphasis on efficiency, reliability, and clear communication with clients and stakeholders—helping transform ideas into robust, market-ready solutions.
