About

Free introductory call
Picking the right mentor matters. You want someone who actually gets your situation, not just someone with impressive credentials. I get it! That's why I'm happy to do a free intro call. We'll talk about where you're stuck and what you're trying to build, and I'll share how I work.

Background
I'm Kirill, CTO at Aspect Health, building AI-first health automation products. Before this, I led R&D at Improvado and ran the AI lab at SOAX. I've also founded a startup, worked as a fractional CTO for years, and spent time at both early-stage companies and growth-stage tech firms. This mix means I understand both scrappy MVP building and scaling teams with real infrastructure constraints. My domain expertise includes:
- AI Agents and Automation
- Large Language Models (LLMs)
- Data Engineering and ETL Pipelines
- Startup Technical Strategy
- B2B SaaS Architecture

Who I work with
- Engineers looking to level up their career, improve their CV, or integrate AI into their workflows
- Founders figuring out their first technical hires, MVP architecture, or how to actually use AI in their codebase

Achievements
- 12+ years of experience spanning startup founding, engineering leadership, and hands-on AI development
- Transformed a company from 15th to the Top 3 in their market through data infrastructure improvements
- Built systems processing 3+ billion rows daily with 5x query performance gains
- Delivered 10,000+ AI-generated scrapers daily and automated 80% of customer support tickets
- Publications with 100,000+ views on developer tooling and AI workflows
- Open source contributions, including merged PRs to OpenAI repositories

What mentees say

5 out of 5 stars

I am an ML Engineer building an in-house AI agentic system. I came to Kirill to ask him the questions I couldn't find answers anywhere but from a person with a deep experience in the matter - since it is quite a new field, there are not that many people to refer to. Kirill was the right choice. Kirill is an extraordinary person with a wealth of experience in building enterprise level AI-powered systems. He is very open, easy to approach person, who is willing to get into the problem and answer the question at the best of his knowledge. He might be especially helpful at brainstorming ideas, solutions and potential pitfalls.
