Hi, my name is Roman. I'm a CTO and technical leader based in Leeds, UK. I run Arrows Digital, where I provide technical consulting. People call me the guy who makes impossible software work flawlessly. I love taking messy, complex systems and refactoring them until they are incredibly efficient. Whether it's AI on tiny devices or fintech APIs where every millisecond counts, I focus on cutting costs and boosting speed.
I also love adding a creative twist to everything. Want to see? Come play around with my interactive portfolio.
