About Me

A modern engineering profile built around curiosity, execution, and the drive to turn complex ideas into useful, elegant solutions.

My approach

Research-led thinking with a practical product mindset.

I am a researcher and IoT enthusiast who enjoys shaping ideas into working systems — from embedded hardware and sensing pipelines to polished digital experiences that feel thoughtful and usable.

With experience across programming, frameworks, hardware, and experimentation, I work with purpose and precision while staying focused on solutions that are both technically strong and meaningful in the real world.

My weakness is my only strength — I can’t give up on anything.
