Hello, my name is
Nikolai Liapin
I'm a software engineer with a focus on SDET. My day-to-day job involves building apps that test other apps, internal tools, working with multi-agent systems, and diving into ML topics like LoRA fine-tuning.
I build things for fun, too: little pet projects I genuinely care about. Liapinsoft is where I share them with the world.
This site hosts everything I publish: game pages, documentation, and support in one place.
I'm also available for freelance and contract work — if you have something that needs building, testing, or automating, get in touch.
