What Drives Me

Beyond writing code, I'm passionate about discovering people, creativity, nature, conservation, healthy living, science, sustainability, renewable energy, and humanitarianism. I believe technology should serve a greater purpose—which is why I'm excited about opportunities that align innovation with positive environmental impact.

When I'm not coding, you'll find me hiking, exploring nature, art and culture, diving into psychology and quantum physics, or practicing yoga and mindfulness. I enjoy sharing my photography with people to make them more conscious of the beauty of nature, in the hope that they protect it for ourselves and future generations. #SaveSoil
