Hi, I’m
Nikita.

I like the point where
engineering meets
“could we?”

I’m a tech lead and software engineer in London, working across distributed systems, developer platforms and agentic AI. I lead teams and stay close to the architecture and code.

Outside that, I build. Creative tools, tiny games, useful experiments. I’m interested in what frontier models can do when you give them real problems, thoughtful direction and a way to check the result.
