More than just
Code
I am a dedicated problem solver who thrives on tackling complex challenges. With a background spanning from Fintech backend systems to Robotics instruction, I bring a unique perspective to every project.
Beyond software, I explore the world through the lens of photography and experiment with hardware using Arduino. I believe that understanding how things work at every level—from the physical circuit to the high-level API—is key to building truly impactful solutions.
