About

I build software that scales - and lead the teams that ship it.

I'm Borislav Koprinski, a passionate senior software engineer. I've been in the industry since 2014, and I still try to improve my craft every single day.

During my time as CTO at 1ForFit, I led the team through process improvements and scaling our platform - making sure our technology kept pace with the rapidly changing needs of the business.

Interests

Computers and software are my biggest passion - for me this is not just a profession, but my whole life. I love business and building things, and I am at my best working across a range of projects that make people's daily lives a little better.

Cars are my biggest hobby: I keep a garage of modified builds, all BMWs for now, with more to come. I also used to play guitar seriously, gigging with three bands along the way: Explicit, Nepukist, and Dismounted.

Sport and a healthy lifestyle are hugely important to me. I do my best to train every day and keep to a healthy diet, mixing the gym with swimming, basketball, and football. Staying fit keeps me sharp and energized for everything else.

Off the clock

Traveling, exploring new places, and road trips with good people.
