About Me

Innovative technology professional with a robust foundation in AI-driven solutions, digital marketing and technology adoption.

My Story

At 18, while studying computing in college, I launched my first business—helping gyms grow with Facebook ads. That early dive into entrepreneurship ignited a passion for building and problem-solving, which led me to combine my love for AI and business. At 19, I moved to Bali, where I developed custom AI solutions for businesses and connected with like-minded entrepreneurs worldwide.

Professional Journey

Eventually, I decided to put my self-taught skills to the test in a structured, high-impact environment. I've taken on a role as an AI Solutions Engineer in London, where I now thrive in the fast-paced world of AI-driven innovation.

What Drives Me

I'm obsessed with solving complex problems—if you dig deep enough, there's always a solution. My journey, from being labeled a "misbehaving ADHD child" to exceeding expectations, taught me one invaluable lesson: mindset beats circumstance & persistence beats perfection.
