Throughout my life, I've earned the endearing nickname "my little inventor" from my grandmother, who recognized my innate curiosity and creativity. From my earliest days, I've been drawn to fixing and discovering things, often working with limited resources. This has instilled in me a passion for problem-solving, and I've become a self-taught individual who thrives on creative solutions. I bring this same spirit of curiosity, resourcefulness, and creativity to my professional endeavors.
