SERVICES

Four ways in.

Fixed scope, fixed quote, no surprises.

I am the one who does the work. No account managers, no handoffs. Three are fixed-quote projects; the fourth is a monthly plan with a public price list. Here is exactly what happens when you hire me.

THE METHOD

The answer is the easy part.

Most of the value is deciding what to measure before anyone opens the data. The same three steps, every time.

  1. Find the real question

    Before any data, we pin down the decision you are actually trying to make, and how we will both know the answer is right. Half of bad analysis is a clean answer to the wrong question.

  2. Measure it honestly

    Then the craft: clean the data, build the pipeline, fit the model or run the test, and check the working at every stage. Every figure ends up traceable to where it came from.

  3. Hand you a decision

    You get a plain answer you can act on, with its confidence stated and its limits named. Something you could take into a meeting on Monday, not a report that gets filed and forgotten.

01 · DATA CLARITY SPRINT

Data Clarity Sprint

Your data chaos goes in. A decision you can defend comes out.

What goes in

Your files, your exports, and the question that keeps coming back. Any format, any state. The messier the better.

What comes out

A cleaned dataset, the analysis, and a short written answer in plain language. You keep all of it.

How long

Short and fixed. We agree the exact dates in writing before I start.

02 · DASHBOARD BUILD

Dashboard Build

A live dashboard your team actually opens on Monday.

What goes in

Your data sources and the numbers your team actually argues about.

What comes out

A live dashboard wired to your sources, with every metric defined in writing, so everyone argues about the same number.

How long

Depends on how many sources you have and how clean they are. Scope and dates fixed up front, in writing.

03 · ML PROTOTYPE & DATA APPS

ML Prototype & Data Apps

A working model or a small data app, shipped in weeks, not quarters.

What goes in

A question that smells like machine learning, and the data you think answers it.

What comes out

A working prototype you can put in front of real users, plus an honest written note on what it can and cannot do yet.

How long

Weeks, not quarters. Scope fixed before I start.

04 · YOUR OWN SYSTEM, MONTHLY

Your own system, monthly

A booking tool that fills quiet weeks. A client list that never forgets a renewal. Built for you, for one monthly price.

What goes in

How your day actually runs: who books, who comes back, what you keep retyping, what falls through the cracks.

What comes out

Your site plus one custom system that does exactly what your business needs and nothing else. No extra buttons. You own the code.

What it costs

A fixed monthly price in złoty, month to month, cancel anytime. The price list is public.

HOW I WORK

How I work.

  1. Scope

    We talk. I write down what goes in, what comes out, and what done means. You sign off on the words, not on a vibe.

  2. Quote

    One fixed number, in writing, before any work starts. No day rates that drift.

  3. Ship

    I do the work, show my measurements, and hand everything over. The code, the data, and the written answer are yours.

Projects get a written quote that does not change after you accept it. The monthly plans have a public price list.
