01 / PROBLEMS I SOLVE
Does any of this
sound familiar?
Your team knows where the friction is.
Let’s turn that into something that works.
01
People are doing the work your systems should do.
Spreadsheets, emails, repeated data entry and an essential process held together by workarounds.02
You want to use AI, but need more than a demo.
Which workflow is worth improving? What data can it use? Who checks the result? How does it fit the business?03
You have a prototype. It isn’t ready for real users.
An AI-built app or proof of concept still needs sound architecture, integrations, security and a dependable deployment.04
Off-the-shelf tools don’t fit the way you operate.
You need an internal application that connects your people, documents and existing systems.02 / WHAT YOU CAN HIRE ME FOR
From a business problem
to a working solution.
I work directly with founders and operational teams: understand the work, build alongside the people using it, and take it into production.
Digitise the work.
Replace manual back-office steps, spreadsheets and disconnected tools with dedicated applications and automation.
Ship the prototype.
Turn an early demo, AI-built app or MVP into software you can run: review the code, fix weak points, connect services and deploy it.
WHAT THIS LOOKS LIKE

Excel + email + repeated data entryOne internal application & connected workflow
An AI demo with no path to rolloutA measured pilot, integration & production deployment
A promising prototypeReliable software, with ownership and a release plan
03 / SELECTED WORK
Real systems.
A product you can try.
Business-critical engineering, applied AI and a product built and launched end-to-end.

Folio
From scanned pages to a book you can actually read.
- Problem
- Scanned PDFs are hard to search and awkward to read on an e-reader.
- What I built
- A browser-based product that turns scans into EPUB and searchable PDF, with local OCR, text review, payments and export.
- The hard part
- Bringing private document processing, a clear user experience and a complete product flow together.
- Outcome
- A live product: upload a scan, recognise the text, review it and download a readable document. The PDF and its text stay on the user’s device.

WaterGarden
Consumer product thinking, mobile UX and the reasons people come back.
More about the work
- Focus
- A product exploration around behavioral design and retention.
- Current stage
- Independent exploration. No public release or usage results are claimed here.
AI inside the workflow
For document-heavy and manual operations: a focused pilot that can become a working internal tool.
More about the work
- Start with
- One repetitive task, representative data and a clear definition of a useful result.
- Build towards
- Extraction or drafting, validation, human review and integration with the systems your team already uses.
- Delivery approach
- Measure quality, surface exceptions and decide what is safe to automate before rolling it out. This is an engagement example, not an undisclosed client case study.

04 / HOW I WORK
Understand. Integrate. Ship.
I don’t stop at recommendations or architecture diagrams. I design systems, write production code and work through the details of making software usable.
Find the right first problem.
Map the process and constraints. Agree what improvement would matter and what a first release should prove.
Build with the people using it.
A short feedback loop, real examples and practical decisions about data, integrations and human oversight.
Take it into production.
A dependable deployment, clear ownership, documentation and a sensible path for maintenance and further work.
05 / ABOUT KRZYSZTOF
Engineer by background.
Builder by instinct.
I’m Krzysztof — Chris for short. Senior software engineer and product builder.
My background spans aerospace engineering, more than a decade in software and business-critical fintech systems. I’m comfortable with complexity — and focused on making it manageable.
Building my own products keeps me close to the customer problem, the experience and the practical work of launching something useful.

06 / LET’S TALK
Where could your team
work better?
Bring the process, the prototype or the problem.
We can start with a 20-minute conversation about what is manual, inefficient or difficult — and whether AI, custom software or a simpler process could help.
You don’t need a specification. A concrete example is enough.
