Fractional CTO
You built it with AI. I make it stop breaking.
I’m Artem Kiselev. I take internal tools built with AI and make them stable enough to trust, so your team keeps building on them without me.

Sound familiar?
Nobody invoices you for this, but you pay for it: idle team hours, slipped client deadlines, data nobody can get back.
None of this means you built it wrong. It means it grew.
- “I’m tired of doing everything myself.”
- “I don’t know how safe this is.”
- “I spend too much time debugging.”
- “Every time we add something, something else breaks.”
- “The person who built it won’t touch it anymore.”
If it keeps breaking, start with Rescue. If it works and you are the one holding it, start with Speedup.
A stable system you trust and can keep developing
Every system needs different rules at different stages of growth. I pick the ones yours needs and build them into the system, so the AI agent follows them without reminders.
Agent context
Without it, the agent forgets what it built last week and breaks it.
Linters
Without them, small inconsistencies pile up until nobody can read the code.
Tests
Without them, you learn a change broke billing when a client calls.
Guardrails
Without them, the agent can delete or expose what it should never touch.
Documentation
Without it, the system works only while its builder is around.
Everything lives in your repo, on your accounts, under your keys. How it works →
Rescue or Speedup
Both start with a $1,900 health-check, done in up to 5 business days. The fee is credited toward the project.
- Your system
- Works, but you check everything
- Good fit when
- You want people and agents to build on it faster, with clearer docs and sounder engineering.
- You get
- You, your people or your agents change it faster, and every change is safe.
- Price
- From $1,900 to $15,000
I reply to every request the same business day. I take no more than three clients at a time. Optional retainer after either →
Where this already works
Nezabudka
Online school
The founders build with AI coding tools and need everything to run without errors or downtime. A non-technical founder now develops a functionally heavy product on their own, using a process I set up: a safety net that holds quality and reliability at a set level by itself.
Weekly → monthly: how often the system needs me. She made 84% of all changes herself, and automated tests grew 4.5 times.
Zetique
An international accounting firm. Its CRM, HR and process tools are built and run by AI agents under my management, on the same practices.
Wondersell
My own group of projects around online marketplaces: we launch fast and shut down what doesn’t work. Built and run on the same practices.
Who I am
I founded Timepad in 2008 and grew it to 200,000 clients and 4,000,000 events. It became one of the largest event management and ticketing platforms in Eastern Europe. I was a CTO and an owner, so I look at technology from the business side. Today I build with AI agents every day and work personally on every project.
Safe to let me in
- NDA first
- Signed before any access changes hands.
- A real contract
- Legally binding, invoiced by my company in Spain.
- Read-only to start
- Anything more for the project, you grant and you can revoke.
- Yours, all of it
- Code, repo, accounts and keys stay in your name.
Questions owners ask
- Do I have to stop using Lovable or similar tools?
- No. You keep building in the tools you know. The point is that it stops breaking when you do.
- Can I stop after the health-check?
- Yes. The report is yours either way, and the fee is credited toward the project if you continue.
- What access do you need?
- Read-only, after an NDA and a signed contract. If the project needs more, you grant it and you can revoke it.
- What if it breaks after you’re done?
- If something I touched breaks, I respond the same business day and fix it free for 60 days after handover. Later changes by someone else and vendor outages are not covered.
- How is this different from a freelancer or an agency?
- I work on your project personally, from diagnosis to hand-off, and everything I set up stays in your repo.
Let’s look at your system.
