For owners who build with Claude Code, Codex or Cursor

A senior next to you, while you build your own system

You are a programmer out of necessity: you run a transport firm, a workshop or an agency and wrote the system it runs on, with an AI agent. Some questions you cannot ask the agent: how to split data for many clients, where backups live, why it goes in circles. You keep building; I sit next to you a few hours a month.

What we do together

Decisions that are hard to undo

Data model, many clients in one database, which hosting, which payment provider. Decided with you and written down in your repository.

Deploys, backups and environments

Set up together on your accounts, so a change goes out from the repository and a backup really restores.

Unstuck in an hour

When the agent loops on the same error, we find the cause on your screen instead of another prompt.

Rules for your agent

A CLAUDE.md or AGENTS.md written for your project, so the agent stops repeating the same mistakes.

How it works

  1. A first call

    What you build, what blocks you, which decisions are coming.

  2. 8 or 16 hours a month

    Live sessions on your screen and questions on chat between them.

  3. You keep the code

    Everything stays in your repository and on your accounts. I do not take over unless you ask.

  4. When it grows

    If clients arrive, the same person can help turn it into a product or join for longer.

Who it is for

  • Owners who build their company system themselves with an AI agent.
  • Founders whose MVP from Lovable or Bolt now has its first clients.
  • Small teams without a senior who want one a few hours a month.

Proof

I run my own projects with coding agents under written rules and hooks, restarted delivery on a mature SaaS with agents, and keep several side projects running on one domain. Fifteen years of shipping software, explained in plain words.

An AI coding agent as a team member, under enforced rules

The problem
Coding agents produce ten times the output and ten times the mess. A team of four wanted the speed without a slop swamp on main.
What I did
I authored the rule set shared by Claude Code and Codex: mechanical checks over written rules, lint and test gates for security, API surface and CSP, agents working on main with hooks, every PR reviewed by a human, AI-assisted content disclosed as such.
Result
In 2026 the agent opened about 30% of merged pull requests across two products and I reviewed about 85% of them. My own output went from under 1,000 to 5,000+ commits a year.

~30% PRs by agent ~85% reviewed 5,000+ commits/yr

Restarting delivery after three years of maintenance mode

The problem
A mature product had drifted into maintenance. The backlog was old and the team small.
What I did
Agent-assisted development under an enforced rule set, help docs migrated from WordPress into the repo as markdown with 301 redirects and i18n, help added to the Definition of Done.
Result
Commit volume up about 40× year over year in 2026, one less server to break during holidays, docs that match the product.

~40× commits YoY docs-as-code

Four side projects on Cloudflare Workers under one domain

The problem
Ideas die when deploying them costs a weekend. I wanted a path from idea to a URL in an evening.
What I did
Korpo Tłumacz, Wyrocznia, Migawki and Przemo (Agent): each a Worker with static assets, Workers AI with per-IP and global rate limits, a cost cap in a Durable Object, R2 for generated images, a first-party PostHog proxy and a CSP without inline scripts.
Result
Live at ciunkos.com/korpo-tlumacz, /wyrocznia, /migawki and /przemo. This page runs on the same pattern.

A senior next to you, while you build your own system

You run a company and build its system yourself with Claude Code or Codex. 8 or 16 hours a month with a senior next to you: decisions that are hard to undo, deploys, backups, payments, and getting unstuck. Together, on your code.

FAQ

Questions

Will you check or grade my code?
No. We work on what you are building next, together, and the decisions stay yours.
I am not a programmer. Is this for me?
Yes, if you already build with an AI agent and want to understand what it does. We talk in plain words.
Can I change the hours later?
Yes, between 8 and 16 hours a month, monthly. Unused hours do not roll over.
What if I want you to build something?
Then it becomes a separate project with its own price, for example turning your tool into a SaaS.
