From a business problem to an architecture your teams can build.
I design systems where business goals, software structure and team organisation have to fit together: logistics, the public sector, insurance, telco and manufacturing, across 22 years. I started out writing the code, so my designs come with the trade-offs, the team boundaries and the cost of change already worked out.

What companies bring me in for
Most work starts with a decision that is expensive to get wrong. These are the ones I see most often.
A new product with an unclear shape
You know the business goal but not yet what to build. I turn it into requirements, the qualities that matter and an architecture a team can start on.
How I workA legacy system or a troubled project
Replace, rescue or rebuild: the options compared on cost, risk and time, so the decision is made while it is still cheap to change.
Work with meA vendor proposal on the table
An independent view of the architecture and the risks before you sign, from someone who has delivered systems like it.
Work with meOne platform for many markets or units
Shared foundations with local rules, as in the DPD platform for 14 countries and the portal for every labour office in Poland.
DPD case study
Three platforms, three kinds of problem
A contract platform for INNIO, a B2C portfolio for a parcel carrier in 14 countries and a nationwide public portal. Each one with the problem, my role, the decision and what it led to.
Contract Lifecycle Management for INNIO
A platform that configures the contracts INNIO signs and simulates their costs before signing, so contracting follows one controlled process.

Three portals that gave a B2B parcel carrier a direct relationship with recipients in 14 countries and 13 business units, each with its own rules.

Read the case studyWhat clients say
From written recommendations by people who worked with me on the client side of these projects.
Piotr doesn't just build, he optimises. He is a ‘safe pair of hands’ for any product team.
Able to create a big picture design and also to go top-down even in very complicated environments. He still has his hands deep on technology.
He was able to fully understand where all of us were coming from, and at the same time offer new, futuristic, way-ahead-of-us kind of solutions.
How I approach architecture
Responsible Software Architecture says what a good design has to take care of. The six-step process is how I get there on a real project. Architectural Kata 2.0 is where people practise it.
- Responsible Software ArchitectureFour pillars a design has to answer to
- Six-step design processFrom requirements to team boundaries
- Architectural Kata 2.0A workshop to rehearse the process
Workshops: practise the decisions
Architectural Kata 2.0 is a one-day workshop where teams take a realistic business problem through the six steps and defend the result in front of a demanding client.
- From business goals to architecture requirements
- Finding system boundaries
- Comparing options and justifying trade-offs
- Communicating architecture
- Testing assumptions
- Using AI in architecture work
Talks, a podcast and writing
A sample. The recordings are mostly in Polish, the articles in English.
Architect, engineer by origin
I started in 2004 writing code, then led teams and designed platforms for logistics, the public sector, insurance and telco. Today I am a Solution Architect and a co-founder of Arpeggia Studio, where I design architecture with clients and run the Architectural Kata workshops.
Facing a decision that’s expensive to undo?
