Hi, I'm Yuri Ly. I work on AI inside a real business and build Telegram products used by millions
Developer and researcher based in Ukraine, writing code since I was twelve. Currently AI lead at KNESS. On the side I run my own Telegram products used by millions
What I'm doing
Main work: AI lead at KNESS Group. I research, build and roll out AI agents (systems that fetch data, make decisions and handle routine on their own) across the company, from picking the problem to stable production. On the side: fStik, QuotLy and a few more Telegram bots; servers and databases all on my own machines. Occasionally I take on AI and automation consulting, picking real business problems, like teaching AI to process documents or handle requests on its own instead of a whole department.

About
Started at twelve, editing uCoz sites with too much time on my hands. Then came PHP, then VK bots, then the Telegram ecosystem I still live inside today.
Millions of people have used something I wrote, mostly through fStik and QuotLy. Once won first place at the official Telegram Mini App Contest, a cool milestone, but not the main focus anymore.
The main focus now is AI that actually works inside a real company. I do that at KNESS, a large manufacturing group, as AI lead: I work with teams across the company to find what's worth automating, build it, wire it into live systems, and see it through to stable production.
On the side I run my own bots and write at @LyBlog.
How I build
For about two years now I've done most of my coding alongside AI agents. Day to day it's Claude, currently the strongest tool I've tested; GPT and Gemini I keep around for verification and comparison. Working stack: TypeScript on Node.js, React / Next.js on the frontend, Python for ML, Telegram through Telegraf, grammY, TDLib, MTProto and Mini Apps. All on my own boxes: Linux, Docker, Sentry, MongoDB / Postgres / Redis
