Work with me
Configure the engagement. See the price before the call.
No “contact us for pricing”. Pick the kind of work, set the size, and you get hours, a price range at my rate and the earliest start date. Bring the brief to the call or send it by email.
From the cost estimator: the size below comes from your estimate. Adjust the weeks and pace if you already know better.
From the app store checker: the store path below comes from your result.
From the runbook generator: monthly care is the usual next step for a system that lives in one head. Pick the hours below.
From the SLA calculator: the monthly reserve below comes from your result. Adjust it if you know better.
From the local model calculator: a private AI deployment usually takes 2 to 8 weeks, depending on documents and integrations.
For agencies: senior hours under your brand, planned month by month.
Company login for internal apps: one day for one app, more if you want one place for all of them.
Looking for a contractor for your team? Fractional or full-time works too; tell me on the call.
From the OpenAPI to MCP generator: the weeks below depend on how many tools you need and on your login.
From the KSeF invoice validator: integration usually takes 1 to 3 weeks, depending on your system.
From the quoting calculator: the weeks below cover the agent, your suppliers and a test set on real enquiries.
Takeover week: five days, then optional monthly care.
Off WordPress: pick the size of the site and the add-ons. If the old site is exposed today, patching it comes first.
From AI Visibility Desk: hours a month on the pages assistants cite, content for buyer questions and PostHog measurement.
Try me: two weeks, five tasks you choose, a price agreed up front, then you decide.
From your company tool to a SaaS product: the weeks below cover tenants, billing, settings per client and moving your own company in as the first client.
Senior next to the owner: hours a month you plan together, sessions on your own code.
From the legacy rewrite estimate: a rewrite usually starts as an MVP-sized first stage next to the old system.
From List Desk: a clean list is step one. The next one keeps every send within Gmail and Yahoo rules: one-click unsubscribe, a suppression list and bounce handling. Pick the size below.
From Signature Desk: one signature set centrally on every mailbox in Google Workspace or Microsoft 365, so nobody pastes it by hand.
From Dashboard Desk: the events your dashboard said were missing, added to the code and checked in PostHog.
From Eval Desk: your test cases run in CI on every prompt change, with a cost cap.
From Quote Desk: the same reading of inquiries, connected to your mailbox, price list and suppliers.
Your estimate $1,350–$1,800
Book a call with this briefHow working with me looks
- A 30-minute call. You tell me the goal, the deadline and what already exists. I ask what would make it a success and what can wait. Free, and you leave with a recommendation either way.
- A written scope within two days. What gets built, what does not, how we know it works, and the price: fixed per slice or hourly with a weekly cap. You can take it to anyone.
- Weekly demos, code in your repo. Working software every week, in your accounts from the first commit. When something takes longer, we cut scope before we move the date.
- A handover you can live with. Tests, CI, a short runbook and a recorded walkthrough. Anyone competent can pick it up after me, including your next hire.
Each kind of work up close
Review of one pull request
For a team that wants a second senior opinion before something risky merges, or a founder who wants to know what the code is really like. Not a full audit: one change, read properly.
One-week audit
For a CTO or founder before a raise, a rewrite, a new vendor, or adding AI features. You get a ranked list and a plan, not a 90-page PDF. I do not fix things during the audit week; that keeps the findings honest.
Ship one slice
For a team that needs one thing done end to end: a feature, an AI agent, an integration. Scope, build, measure, hand over. The best way to try working together before anything bigger.
MVP or product build
For a founder with a validated idea and a budget. Auth, billing, analytics and deploy from week one, a demo every week. Not a fit for an idea nobody has tested yet: validate it first.
Fractional tech or AI lead
For a company with developers but no senior technical voice. I join a few days a week, make the decisions written down and reviewable, and help you hire your permanent lead. I do not replace the team.
Maintenance and upgrades
For a product that works and should keep working: framework upgrades, dependency bumps, the legacy corner nobody dares to touch. Tests first, then changes.
A senior with AI agents or a classic agency?
I build with coding agents every day; they write most of the code and I design, decide and review every change. For the right project that makes one senior several times faster than before. The cost estimator lets you set that multiplier and shows what it depends on.
I am likely the better fit for a new product or a well-scoped slice, when one person can make decisions within a day, and when you want to see working software weekly without paying for coordination.
An agency is likely the better fit when you need many people in parallel from day one, 24/7 on-call, formal processes for a large organization, or several disciplines at once (brand, content, native apps and backend together).
In regulated work (medical devices, finance, children’s data) validation, audits and sign-offs set the pace, not typing. AI still helps, but the speedup is smaller, and I will say so before we start. Low risk appetite is often the right call there.
When I am not the right choice
- You need a team of ten next week.
- You need someone on call nights and weekends.
- You want the cheapest hours, not the fewest.
- The idea has not met a single customer yet. Start with the free idea validator and ten conversations.
How I work
- Confidential by default. NDA is standard. I never show your project, name or screenshots without written consent, which is why this site names no clients without permission.
- Your code, your accounts. Code and data stay in your repository and accounts. AI tools run with training on your data turned off, and secrets never reach a model.
- A handover you can use. Every project ends with the same checklist: a README that gets it running, one architecture diagram, written decisions, CI, a runbook and a recorded walkthrough. It is done when someone outside the project can run it from the docs.
- Boring technology where it counts. I pick a stack you can hire for. Anything experimental needs your yes and an exit plan.
- Approach matched to your risk appetite. Prototype, product or regulated: the level decides how much autonomy the agents get and how much review and validation each change needs.
- Everything checkable. Every number on my pages links to its source. My tools are free, and the idea validator skill is open source (MIT).
My pledge
- Reply within 24 hours. I reply within 24 hours on working days, personally, not a bot. Weekend messages: by Monday noon.
- Late means free. If I am late, the first hour of work is free. You do not have to ask.
- Scope in writing within 24 hours. A free 30-minute call with no company deck, then the scope and the price in writing within 24 hours. You decide.
- The person who does the work. You talk to the person who does the work. No sales layer, no handoff.
- Follow-up only with news. I follow up only when I have something new for you. Never a "did you see my offer".
- Honest "not a fit". If I am not the right person, I say so on the call and point you to someone who is.
Three risk levels, three ways of working
| Level | When | How I work |
|---|---|---|
| Prototype | You want to learn fast and may throw it away. | Agents move fast with light review, on test data only. Nothing goes to production from here. |
| Product (default) | Real users, real money. | Agents work under project rules; I review every pull request; tests and CI gate every merge; staging before production. |
| Regulated | Medical devices, finance, children’s data, or a strict client policy. | AI helps with drafts and tests; validation, traceable reviews and sign-offs follow the standard. Only models on your approved accounts, or none at all. The speedup is smaller, and I say so up front. |

How it is calculated
Hours are a range: weeks or days times hours per week, plus or minus 10 to 20 percent for the unknowns, depending on the kind of work. The audit and the PR review have a fixed size. Fractional months count 4.33 weeks. The price is hours times the rate; the full range uses my lowest and highest rate.
Questions
Is this a quote?
It is an honest starting point. Within 24 hours after a 30-minute call I send a written scope with a fixed price or a capped number of hours. The final number usually lands inside the range shown here.
Fixed price or hourly?
Both work. Audits and reviews are fixed. Builds can be fixed per slice with a demo at the end, or hourly with a weekly cap. Fractional work is billed per day.
How do you invoice?
As a Polish business (B2B), monthly or per milestone, in PLN, EUR or USD. EU businesses get a reverse-charge invoice without VAT.
Why can you show prices when agencies do not?
Because it is just me and the rate does not depend on who is asking. Coding agents under rules make me faster; you pay for the hours a senior engineer spends, not for a team on the bench.
When can you start?
Now. The earliest start on this page is calculated from today and my calendar, and it changes when my availability does.
Who owns the code?
You get all of it, written by hand or with agents: it lives in your repository and your accounts from the first commit, and the contract transfers to you whatever rights exist in it. To be honest about the law: under current guidance, parts generated by AI without enough human creative input may not be protected by copyright at all (US Copyright Office, 2025). So your protection rests on the contract, confidentiality and the fact that the code is yours to hold, not on copyright alone. I keep nothing that stops you from working with someone else.
Will you sign an NDA?
Yes. I also never name clients without their permission, which is why you will not find client names on this site.
Do you use AI on my code?
Yes, coding agents are how I work. They run on your accounts, or on my business accounts if you have none, always with training on your data turned off. Secrets never reach the model, and I review every change before it reaches you. I pick tools and models to match your appetite for risk: the privacy of your code and data matters more to me than speed. If your policy forbids AI tools, I follow it; the price then reflects my hours without agents.
Time zone and language?
Poland, Central European Time. English is my working language, Polish is native. I have worked across a nine-hour time difference with weekly calls and written status in between.
Can we stop early?
Yes. Work comes in slices, each finished and in your repo, so stopping after any slice leaves you with working software. The notice period goes into the contract.
Not sure what you need?
Book the call anyway. Thirty minutes, free, and you leave with a recommendation even if it is not me.
