300+
orders in the first 3 days
An order generator for a group of e-shops replaced two legacy applications. It ran in shadow mode for several weeks and now sends orders to the manufacturer in their format, after an operator check.

Freelance engineer. I build and run systems with AI agents.
In IT since 2009. From 2021 to 2026 I led development at a small web agency: the team, delivery, estimates, servers and production. Since 2026 I bring that experience directly into companies as a freelance engineer. I build with AI agents, but I own the architecture, the data model, the security and every decision, and I answer for what runs in production: tests, monitoring, backups with verified restores.

Most of my commits today list Claude as a co-author. Agents make me faster, but they add a kind of error that only a human catches. In three months I logged eight incidents caused by agents. No automated check caught any of them and human review caught all of them. My process is built around that.

We agree on a number of days per week and I work as part of your team for the long run, without a hire and without agency overhead. You set the priorities. I get AI into production and teach your people to work with it.
One process or system as a bounded, fixed-price project: orders, inquiries, an owner dashboard. We start with mapping and end with a handover.
I go through your company with you to find where work depends on a person today and what should run on its own. You get a list of those places ranked by impact and a fixed quote for the first one.
I build in small batches and run the new process next to the old one on your real data. We switch over only once it is visibly working.
You get documentation and a trained team. The code and the data are yours. If you want, I keep running it: monitoring, backups with verified restores, and changes.
The goal is that you do not need me for day-to-day operation. Another developer can take over, and nothing ties you to me.
Three shapes. Which one is yours usually becomes clear during mapping.
For a company that knows it needs something and wants to know exactly what, and what it costs.
Three to five days in which I go through your processes, systems and data and talk to the people doing the work today. You get a ranked list of opportunities and a fixed quote for the first project.
For a company with one specific process or system.
I build it, test it, document it and hand it over. Automated tests, a run next to the old process, documentation, training, and code and data that belong to you. The price is fixed and known before we start.
For a company that needs a senior engineer for the long run, but not full time.
An agreed number of days per week. You set the priorities. I build, operate what we have built, and train your team to work with AI on your real tasks.
I quote after mapping, always up front and always fixed. I do not bill by the hour.
I am Vít Šafařík from Opava, Czechia. I have been in IT since 2009, after seven years in B2B sales, and a developer since 2018. From 2021 to 2026 I led development at a small web agency. Since 2026 I bring that experience directly into companies as a freelance engineer. I build with AI agents, keep architecture, data and security in my own hands, and answer for the result.

A few sentences are enough: what should work, what does not work today, or whether you are looking for someone a few days a week.
