Precise AI engineering.
Built to stay visible to ChatGPT, Gemini, Grok and Claude.
What do you need?
We design, build and run it: frontend, backend, payments and the pipeline around it.
- Next.js, TypeScript, Node.js and Postgres — a proven stack that's easy to hire for
- Sign-in, Stripe billing, e-mail and admin tools built in
- Tests, CI/CD and preview deploys from the first week
- NDA on request — the code and IP are yours
One Flutter codebase for iOS and Android — native Swift or Kotlin where it matters.
- Flutter, Swift and Kotlin; offline-first data and push notifications
- An API and backend — built new or connected to yours
- fastlane CI: TestFlight, Play tracks and staged rollouts
We audit it and make it hold up inside a large system.
- Full audit of AI-generated code: security, architecture, performance
- Fixes and refactors that fit your existing system
- Automatic checks so the next AI edit can't break production
- We sign an NDA — your code stays private and only yours
We design and set up a private server where your coding and business agents run in parallel — fenced in, logged and reviewed.
- One container and git clone per agent, with CPU and memory limits
- MCP tools for your systems, with human approval before anything is sent or released
- CI as the gate, plus a log of every run: what changed and what it cost
- Private VPN access and scoped tokens — no production secrets within reach

Precision over promises.
Led by Anton Tkachenko — fifteen years of building production software across web, mobile and interactive systems.
Every project we take follows the same order: measure, specify, build, test, document. Nothing ships untested. Nothing is handed over undocumented.
Our method comes from game engineering, where a system must behave identically every time. We apply it to AI search, AI-built software and business automation.
A senior lead on every project, from audit to production. A limited number of clients per quarter.
