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.
| Cardputer AI | Chatting with a tiny chip. Real AI in your pocket, running 8M parameters on only 512KB of RAM. |
| TinyTalk 2 | The tiny brain. An 8M-parameter model that actually knows when to stop talking or when it doesn't know an answer. |
| Hazke | A whole galaxy on a chip. 16 star systems, 3D flight, and a living economy, all computed from a single math seed. |
| Card Craft | Survival games on a micro-chip. Mine, craft, and survive in 3D at 30fps on hardware that shouldn't be able to do it. |
| GhostAI | An AI agent that doesn't just scan for bugs, but also executes the actual breach. It finds cracks in vibecoded apps, proves the exploit works, and then helps you patch it. Totally local and private. |
| ESP32 Cleaner | Deep cleans SD cards without you ever pulling the card out of the slot. |
| Follower Tracker | The tracker you actually wanted. See who unfollowed you without giving up your password or paying a subscription. |
| Memorable Password Generator | Strong passwords using real words. Simple, fast, and zero tracking. |
