About

Mateusz Łukaszczyk

I work with companies and organisations that are already up and running and have a technology problem bigger than one small fix.

Who I am

I fix, connect and build the systems your business runs on. Before that, I ran a tutoring school with a team of nine and then founded Immersivum. Budevo and Invessly came later.

I graduated in international relations and applied linguistics at KUL and studied for a year in the United States. Outside work I run the travel channel Odkrywczo.

How I work

  • One accountable person

    My name is Mateusz Łukaszczyk. You talk to me and I do the work. From the first step to go-live you deal with one person. The contract and the VAT invoice come from EVEL sp. z o.o. (VAT ID PL5252869036).

    After each step you get a written document, and flows run on your company's own accounts.

  • AI tools under control

    I work with AI tools (agents) that I direct myself, and I check every change they make. I use them so that prototypes and new versions are ready sooner. No change reaches your live version without your approval.

  • Stages, not on-call duty

    I work in paid stages with an agreed scope. I do not run a 24/7 emergency service. Support after launch is agreed separately, with its scope and response time written into the contract.

After you send the brief, you see a confirmation on screen, and a human reply comes by email within 1 working day.

How I work with AI

Language models are part of my toolkit in the same way as a code editor or Figma. I am personally responsible for the design, the quality of the build and the tests.

  • What AI does

    First drafts of code and layouts, copy variants, data migrations, tests and control screenshots.

  • What I do

    Talk to you, decide what to build and how, check every version, and answer for the quality of the finished project.

  • What stays private

    Your customers' personal data, passwords, documents and financial data do not go into models unless we agree on it in the contract. Repositories are private. Details in the privacy policy.
