Code โ€ข Create โ€ข Innovate

Turning ideas into reality

I'm a software developer specializing in IoT systems, LLM applications, and full-stack development. I have a unique background that combines software engineering with hardware integration, mechanical design, and industrial automation.

My journey spans from building color-tracking robots with Arduino to developing sophisticated LLM chatbots with LangChain and FastAPI. I'm passionate about creating solutions that bridge the physical and digital worlds, whether it's through IoT devices, PLC programming, or modern web applications.

Currently pursuing my MSc in Computer Science and Engineering at Soonchunhyang University in South Korea, focusing on AI, Machine Learning, and Deep Learning research. I graduated with a BSc in Information and Communication Technology from the American University of Phnom Penh, bringing both advanced academic knowledge and hands-on experience in diverse technologies including C#, React, Android development, and embedded systems.
