I'm Sergey, I design services and build them with AI.
Notion systems, n8n automations and my own applications. I work out the architecture myself and drive the implementation through AI — one person across the whole chain, from idea to production.

Solutions
Ready-made solutions you can adopt one at a time
Parts of systems I have built for clients. They work together, but each can be implemented on its own, around your process.
Project launch and the team5
The whole chain: how the links work together →1 · Template

1 record
instead of picking the owner in 100–200 tasks
3 · Access

About
I am Sergey Revin. I am a service architect: I work out how a system should be put together and take it all the way to production. Increasingly the implementation runs through AI — I set the task and hold the architecture, it writes the code. Behind that are more than ten years in IT management, so I look at a product from the operations side as well as the feature side: what breaks, who fixes it, and what that costs. Currently co-founder and CEO of Nooka Ai.
