How I Work

Building the
right products.

“I diagnose before I design.”

Most design work fails at the brief. The wrong problem gets solved beautifully, and nobody notices until the metrics don’t move. The first job is always finding the right problem.

01 — Principles

How I think about product work.

01
Prioritize ruthlessly.
Implementing the 80/20 rule in product building — focusing on what truly matters and diligently cutting what doesn’t. A small fraction of decisions carry almost all of a product’s outcome. Find them. Invest there.
02
Diagnose before you design.
The need to deeply understand complex problems before attempting to solve them. Most design work fails at the brief. The wrong problem gets solved beautifully — and nobody notices until the metrics don’t move.
03
Build deep understanding.
Thorough knowledge of users, clients, their needs, motivations, and challenges — including stakeholders and team dynamics. This also extends to understanding what the business actually needs, not just what was asked for.
04
Adapt the process.
There’s no one-size-fits-all in product development. Adaptability according to user and business needs beats a rigid framework. Embracing flexibility and agility is the only way to stay relevant.
05
Systems, not screens.
A holistic approach considering the broader ecosystem — the full journey, edge cases, empty states, and error conditions. Good design at one screen breaks at thirty. Think in design systems, not just deliverables.
06
Encourage interdisciplinary teams.
Teams that exchange knowledge and experience from various disciplines — engineering, product, business — collaborating closely with each other, produce consistently better outcomes than siloed specialists.
07
Data over opinion.
Making product decisions based on verified data. Not opinion polls dressed up as research. Strong opinions, weakly held — and updated when the numbers say so. Set KPIs before shipping, not after.
08
Ship, then learn.
Quick iteration and validation of assumptions through MVP development — testing understanding against reality, adjusting accordingly. Real signal comes from real users in real conditions.
09
Honest collaboration.
Honesty, openness, and respect are the load-bearing elements of any team that ships good work. No politeness theatre — direct, evidence-led feedback that isn’t personal. That’s how trust is built.
02 — Approach

How this translates in practice.

I come up through scrappy B2C startups, then a software house, then a B2B analytics platform, then a European bank, then a unicorn in Silicon Valley, and now back to fintech. Every context taught me the same thing in a different accent: a handful of decisions carry almost all of a product’s outcome. Find them. Invest there. Have the discipline to leave the rest alone.

I work best embedded with a product squad — close to PM, close to engineering, in the room where trade-offs get made. I don’t need a full brief to start, but I need to understand the actual problem before I start designing anything. That means I’ll ask harder questions upfront and run faster once we’re aligned.

I’m direct with feedback and expect the same in return. I document decisions. I work async-first when the team is distributed. I treat the design system as a product, not an afterthought. And I believe the best design is the one that ships and moves a metric — not the one that looks impressive in a presentation.

03 — Engagements

Three ways to work together.

Format 01 · Senior Product Designer
Full-time employment

Looking for a senior product designer role at a product-led company where design is taken seriously — complex problems, shipped outcomes, real ownership.

Format 02 · Consulting
Senior design consultant

Part-time consulting engagement. Diagnosis first, then execution — working across discovery, design, and delivery. Best for teams who need a senior design partner without a permanent hire.

Format 03 · Sprint
Focused design sprint

2–3 weeks on a single product problem. Discovery, design direction, validated prototype, and hand-off. Best for 0→1 problems or a stuck roadmap item that needs a fresh senior pair of eyes.

04 — Recommendations

What colleagues say.

Wojtek is the best person I hired, ever. He is obsessed with applying structure to chaos — be it via process design or careful and deliberate communication. His calm demeanor is a great asset, but it actually hides a very competitive nature and a need for speed in execution. He is an expert in User Experience and Product Design, with a very analytical approach to both generating and evaluating user insights.

Wojtek consistently demonstrated an exceptional level of effort and energy in the product designer role at Housecall Pro. The dedication to achieving excellence was evident in Wojtek’s work, and I am grateful for the valuable contributions Wojtek made to our team. Working with Wojtek has been a pleasure, always exemplifying professionalism and unwavering commitment.

I worked with Wojtek during my first year at Housecall Pro and he is one of the most organized and thorough designers I have worked with. He set a standard for the rest of the design team in terms of user journeys and async work. He goes into the depths of a problem and fully analyzes it before tackling flows that best suit the user’s solution.

You can take one look at Wojtek’s design files and realize that, as a designer, you’re falling short in some way. His files are incredibly clean, organized, and easy to understand. When Wojtek joined the team, his attention to detail blew me away and I instantly knew that I needed to step up my game.

I’ve worked with Wojtek for several months and I can confidently recommend his work. Wojtek’s a great team player, always ready to help us by consulting on design or product features. He took very big ownership of his work and demonstrated amazing organizational skills and an impressive level of emotional intelligence.

I highly recommend Wojtek as a Product Designer. He has a deep understanding of user needs and knows how to design products that meet and exceed their expectations. His ability to translate complex ideas into simple, elegant designs is truly remarkable. Excellent team player and collaborator.

Wojtek is the most well-organized designer I have ever had the pleasure to work with. His design documentation is incredibly thorough and meticulous, and served as an example for all product designers on the team. On many occasions, his analytical approach helped me look at the problem from an entirely different perspective.

I worked with Wojtek on a fintech product for over a year. He had a great understanding of his domain and, despite many challenges, handled them well. Wojtek has an analytical approach and it shows — his work is thorough and detailed. Excellent at communication and planning. Funny, easy-going, and always open to discussion.
