Philosophy & Values
Creativity is the amalgamation of previous ideas. This observation, in conjunction with my natural curiosity and nomadic lifestyle, set the building blocks for my work.
Since my preteen years, I’ve been captivated by the transformative power of technology. Coding became my passion, and I dedicated myself to mastering programming languages and frameworks at the forefront of innovation.
My Work Happens on the World Stage
