I build
clear products
in complex
systems.
Twelve years across fintech, SaaS, and enterprise, most recently in complex, regulated products. I take the work end to end - framing the problem, deciding what we build first and how we’ll know it worked. Now I prototype in code as well, with AI agents, and stay honest about what they can and can't do.
Hard parts I’ve designed for.
-
Limits
How much, how often, and what people see before they reach the ceiling.
- Transaction limits
- Near-limit warning
- Reset timing
- Who can see limits
-
Rejections
The no is part of the flow: why it happened, and what to do next.
- Unexpected rejection
- Credit line eligibility
- Recovery path
- Next steps
-
Verification
Proving who someone is in steps a person can finish.
- KYC
- AML
- FATCA / CRS
- Source of funds
- Document checklist
-
Agreements
Getting every party and approval in order before anything is binding.
- Signatories
- Review & approvals
- Sign agreement
- Closing
-
Roles & permissions
Who can see and do what, when one product serves several kinds of people.
- Five roles, one system
- Limits hidden by role
- Approvals by role
- Internal admin panels
-
Waiting & status
What people see while a decision is pending - and when it changes.
- Pending review
- Approvals in progress
- Real-time notifications
- Transaction history
-
AI in the product
Bringing AI into a product where it earns its place - and designing where it stops.
- Where AI helps, and where it stops
- A person checks the output
- Honest limits in the UI
-
AI in the process
A product process already run with AI: framing, research, prototypes in code - checked against evidence.
- Framing and research synthesis
- Prototypes in code with agents
- My process as a skill, with evals
Three outcomes. Real proof.
A system being built underneath me.
Led onboarding design in a half-built, regulated platform - traded the requested UI audit for discovery; the 109-story map became backlog and roadmap.

What people I’ve worked with 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.
Marcin GrodzickiGeneral Manager · Housecall ProWojtek 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.
Stumpy AvjeanVP, Product Design · Housecall ProI 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.
Jen ThorneycroftSenior Product Designer · Housecall ProYou 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.
Allen BoitzSenior Product Designer · Housecall ProI’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.
Michał BiechońskiSoftware Engineering Manager · Housecall ProI 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.
Hanna KuczaraSenior QA Engineer · Housecall ProWojtek 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.
Oliwia IgnaszakProduct Designer · Housecall ProI 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.
Dominik NieuważnyStaff Software Engineer · Housecall ProI had the opportunity to work with Wojtek in the Professionals tribe at Otodom - he was part of the Primary Market monetization team while I was on the C2C monetization team. We were both aware that we were assigned to demanding projects, where the business had ambitious monetization growth plans scaled to x4. Despite the complexity, the organisational chaos and high expectations, Wojtek handled it very well - he managed his project with confidence and kept things moving even under significant pressure.
Wojtek consistently demonstrated strong ownership over his projects - he didn’t wait to be asked, he proactively drove work forward, shared his thinking during Design Critiques, and came prepared with alternative solutions when the first direction needed rethinking. I also appreciated how he kept the knowledge flowing within the tribe - sharing design observations, new industry trends, and sparking conversations that went beyond our immediate projects.
On a personal level, Wojtek was a reliable and supportive colleague. I could always count on him when I was away, and I truly valued our casual design conversations.
Magda KrukowskaSenior Product Designer · NetguruWorking with Wojtek on the fund administration project was an exceptionally positive experience and one of the strongest cross-functional collaborations I have had on a project. His engagement, ownership, and professionalism had a significant impact on the delivery process and cooperation with the client. The quality and impact of Wojtek’s work were additionally confirmed by very positive feedback received directly from the client stakeholder.
Wojtek demonstrated full ownership of the design process end-to-end. He proactively coordinated activities, managed priorities, and ensured alignment across streams. He took responsibility not only for design deliverables but also for the overall progress and quality of the work.
His cooperation with the client-side designer and product owner was seamless and highly effective. Wojtek coordinated activities flawlessly, ensuring smooth communication and alignment between all involved parties.
Communication is one of Wojtek’s strongest assets. He consistently prepared very detailed progress updates and shared them with the client on a daily basis, providing full transparency and visibility into ongoing work, decisions, and next steps. His communication style is structured, proactive, and stakeholder-oriented, which helped maintain trust and alignment throughout the engagement.
Wojtek demonstrated strong awareness of risks, dependencies, and changing project dynamics. He actively identified potential issues early, mitigated them whenever possible, and communicated concerns clearly and proactively, helping maintain delivery momentum and reducing uncertainty. A particularly valuable aspect was his adaptability to evolving project requirements. Initially focused on a single stream (NPO), he successfully adjusted his approach when project priorities changed and smoothly transitioned into coordinating work across three parallel streams: NPO, Legal Entity, and Distributor - while effectively leveraging and coordinating client-provided assets. He managed this shift very well, ensuring continuity and alignment.
His approach to design is highly detailed, structured, and methodical. He pays close attention to details while keeping the broader product context in mind. The level of preparation, organization, and thought process behind his work positively influenced both project execution and collaboration.
Artur BorzęckiSenior Project Manager · NetguruI had an opportunity to work closely with Wojtek as a Product Analyst, providing data for his product design and verifying impact of features he had designed. Wojtek is a very thorough and well-organised person. He believes in data-driven decision making and applies it very consistently in his work. His competences go far beyond designing - Wojtek has proven to be a very inquisitive researcher.
Marek MłodożeniecUX Researcher · Sotrender (reported to Wojtek)I had a pleasure to work with Wojtek for over a year. He is an experienced designer with product management knowledge and a holistic approach to developing end-to-end products. Wojtek has strong attention to detail and user-centred design, as well as the design process itself. He’s also a great mentor and funny, easy-going person. Thanks to him I’ve grown as a UX Designer.
Aleksandra WancisiewiczSenior Product Designer · Sotrender (reported to Wojtek)Thanks to Wojtek’s ability to communicate and willingness to share knowledge I understood the specifics of the product from the designer’s side. He presented the results of his work in an incredibly clear way and made data-driven decisions in the design process. As a colleague, always open to discuss the problem and help.
Lidia KołakowskaAnalytics Engineer / Product Analyst · SotrenderThe cooperation between us was very good. We worked together on the development of Sotrender on the designer-programmer line. Together with our teams, we implemented some interesting features. He will always give interesting advice on both product and technical matters.

Complexity doesn’t disappear when you simplify - it moves to someone. Tesler named three places it can go, and every one of them could refuse. We’ve added a fourth that can’t.
