Interests
Apart from being a web developer, I enjoy developing my spiritual journey in Christianity. I'm a strong believer in a purpose driven life and always seek to help other discovering their own life purpose and living their best.
When I'm not being my most productive self, I spend a large amount of my free time playing games with my friends, reading books and being part of entrepreneurship projects.
