Photography of Mount Sefton in New Zealand
Victor Balaniouk

You may be wondering why there's a nature photo on the landing page of a developer portfolio. To be honest, I simply find it beautiful. I took it in the summer of 2023 while visiting a friend in New Zealand.
P.S. I highly recommend visiting New Zealand at least once in your lifetime, you won't regret it!
