Hi, I'm Szymon.
I'm a freelance data and systems analyst. I work out how a business actually runs, make sense of its data, and build the automations and small applications that take the repetitive work off someone's plate. Increasingly, that means using AI, where it actually helps, not because it's trendy.
That comes from five years inside logistics operations: rolling out new systems, working alongside the developers who built on top of them, and creating the reports, KPIs, apps, and automations the business actually ran on. I was always drawn more to the analysis and the building than to managing people, which is why I went out on my own at the end of 2024, to do exactly that for other companies. And it's the work where I feel most in my element.

01
App building
- How I work
- I build small, purpose-built applications instead of forcing a generic tool to fit: the backend, database, and logic a process actually needs, nothing more. It starts from the actual workflow, not a feature wishlist, so nothing gets built that won't get used.
- The effect
- A tool shaped around how the business actually works, not the other way around. It stays simple enough to adjust as the process changes, without needing a rebuild each time something shifts.
02
Automation
- How I work
- I find the repetitive steps first, then automate them with n8n, using AI where it earns its place, and plain logic where it doesn't. That might mean moving data between systems that don't talk to each other, generating reports on a schedule, or triggering the right person at the right step.
- The effect
- Work that used to eat hours every week becomes a few minutes of checking that it ran. Nobody has to remember to do the boring part anymore, and the time it frees up goes toward the work that actually needed a person.
03
Business & systems analysis
- How I work
- I map how a process actually runs, not how the org chart says it should, using BPMN, user stories, and a close look at the systems involved. That usually means sitting with the people doing the work day to day, not just the ones who wrote the procedure.
- The effect
- A spec developers can build from immediately, instead of a vague ask that gets reinterpreted three times. It also tends to surface the real bottleneck, the step everyone complains about but nobody had mapped out clearly enough to fix.
04
Data analysis
- How I work
- I pull data out of whatever systems it's scattered across, clean it up in Python and SQL, and build the pipeline that keeps it that way. From there it's usually a dashboard, a recurring report, or one source of truth instead of five spreadsheets that all disagree.
- The effect
- Numbers people can actually trust, without the monthly scramble to reconcile them. Decisions stop waiting on someone double-checking a spreadsheet before a meeting.
