Hey there 👋

My name is Dat, but people call me David. I was born in 1997 in a small town in Czechia, the heart of Europe. Grew up with computers when my parents bought us one at an age of six and fell in love with technology ever since.

As a software engineer, currently studying at CTU Prague, I always wanted to make products with usability and usefulness in mind, finding the right blend of tech and domain knowledge to create memorable and polished experiences.

Aside from working with startups and agencies such as Spendee and Cleevio, I attend hackathons across the globe. With a few victories under my belt. In my spare time, I do enjoy dabbling with photography and playing badminton.
