Developer. Designer. Frontend Enthusiast.

My passion for technology started when I was six. I was given an iPhone 3G with no SIM card. Through online resources, I learned how to bypass activation. From there, my interest expanded to development. I have been developing websites, apps and Unreal Engine experiences for creators.
