AI engineer with a founder's spirit.

Demo Day · nFactorial Incubator 2026 · pitching Linetta

I build AI products end-to-end: market research, product decisions, LLM pipelines, backends, and the interface people actually touch. I like owning the whole loop: find a real problem, ship a product, watch the numbers, iterate.

Right now I'm building Linetta, a mental-health app, and mentoring the next generation of engineers at AI Trend.

I'm on X, GitHub, and LinkedIn. Here's my CV: English / Русский.

Work

Linetta Founder & AI Engineer 2026

A mobile app for mental health, my main project. Born inside nFactorial Incubator: I did the research, designed the product, built it, and took it to the App Store. Paying users from the first months: $910 in revenue so far, and growing.

Freelance Backend & LLM Engineer 2023–2025

Shipped AI products and automations for real clients, end to end:

Hi5: platform for a private school; landing page plus a Telegram payment bot with automatic OCR receipt verification. Confirmed payment → the bot issues access by itself, no manual moderation.
Course-registration bot: a Telegram bot that handled course signups and onboarding for 3,000+ people.
Expert Finance Group: landing page and an AI lead-qualification bot for an accounting firm; OpenAI-driven dialogue that pre-screens inquiries.
Coach Breath: Telegram education platform for an 18-lesson video course with an AI mentor that reviews homework in the trainer's own style.
