I'm Aleksandra, a Digital Product Designer & UX Researcher.

Hi there!

I'm Aleksandra, a Digital Product Designer & UX Researcher.

I have 10 years of international experience in design agencies and software development companies. With a background in design and social sciences, I cover the entire design process — from discovery to handoff. I have experience in industries such as pharmaceutical, sustainability, automotive, smart home technology and connected cooking appliances.

I help product teams adopt a user-centric perspective, uncover unmet needs through in-depth interviews, harness the creativity of every team member by facilitating design sprints and brainstorming workshops, minimize the risk of building features nobody needs through rapid prototyping and testing, enhance product consistency with well-structured design systems, and reduce friction by conducting usability testing.

I speak Polish as native language and I am fluent both in English and Spanish.

Who I've Worked With

Featured Case Studies

From Design Sprint to MVP

Electronic Lab Notebook

From Design Sprint to MVP

Chemaxon aimed to expand its portfolio with a web-based Electronic Lab Notebook (ELN) for synthetic chemists in early drug discovery. I was responsible for designing this new product, collaborating with an agile team. I led a Design Sprint, interviewed scientists, iteratively designed and tested Figma prototypes, and evaluated feature ideas with Kano questionnaire. Insights shaped the MVP, which was released to early adopters. I also contributed to building a Design System for consistent UX. Feedback from early users highlighted the ELN’s ease of use as a key strength.

Uncovering User Needs to Drive Monetization

Airly Data Platform

Uncovering User Needs to Drive Monetization

Airly aimed to monetize its air quality data platform, previously offered for free with sensors. My task was to understand how users from Polish councils were using the with the app. Using Amplitude data, I identified the 10 most engaged councils and recruited 5 users for in-depth interviews. I uncovered 3 key use cases, including one critical need not supported by the tool—creating yearly city reports with air quality data. To address this, I performed desk research, collected real examples of air quality data visualization, collected requirements and redesigned the chart component to support this use case, improve user value and increase engagement.

Improving an AI-driven Tool through User Research

Airly AI

Improving an AI-driven Tool through User Research

After the launch of an AI-powered air quality assessment tool by Airly, I was brought in to gather feedback from early adopters in the UK. I interviewed over 70 air quality consultants across 20+ companies to evaluate their experience. Based on the insights, I measured the UX-Lite and NPS score, identified 13 features that were later implemented, created Job-to-be-done map and proposed two new assessment types with supporting wireframes. I learned that while users appreciated the efficiency gains, many expressed concerns about trust in AI-generated results and the need for manual verification.

Designing a Subscription Funnel for Revenue Growth

Chemicalize

Designing a Subscription Funnel for Revenue Growth

Chemicalize, a cheminformatics platform for university students and teachers, aimed to replace its outdated credit system with a subscription-based model. I was responsible for designing a new purchase flow to encourage free users to upgrade to paid plans, while also refreshing the visual design of the application. My work focused on simplifying the upgrade process and highlighting the value of each plan. As a result of these changes, the platform saw a tenfold increase in yearly revenue.

Optimizing Lab Data Experience for Scalable MVP Growth

Assay

Optimizing Lab Data Experience for Scalable MVP Growth

Chemaxon’s team aimed to rebuild an MVP for Assay Scientists using modern tech to enable feature growth. I redesigned the UI with custom Material UI components and improved UX through iterative testing. Usability tests and interviews revealed that users needed more than data standardization—they wanted seamless lab instrument data uploads, outlier removal, and clear visualizations for decision-making. I translated these insights into a vision for the ideal user experience.

What I Bring to the Table

I help teams deeply understand their users

Through user interviews, observation, and journey mapping, I uncover real needs, pain points, and motivations. My research goes beyond surface feedback to reveal what truly drives behavior, helping teams move past assumptions and focus on solving the right problems for the right people.

I turn research into actionable design

I bridge insights and execution by turning findings into clear user stories, quick prototypes, and prioritized ideas. I facilitate design sprints and workshops that bring teams together to explore and validate solutions early—ensuring designs are usable, relevant, and grounded in real-world needs.

I reduce product risk and improve user experience

I uncover usability issues and product gaps through testing and competitor analysis. By supporting continuous discovery and creating lightweight research processes, I help teams stay aligned with evolving user needs—leading to more confident decisions and better user experiences.
