Simplifying Complexity
With Clear Design

Hi, I’m Grzegorz. I design digital products that solve real problems and support everyday work — from standalone features to full product ecosystems. I work end-to-end, from research and structure to interface and implementation. I’ve worked in remote and hybrid setups, both as an individual contributor and in leadership roles. I create user-friendly digital products and led design teams that make both users and developers happy.

Based in Gliwice, Poland, I craft digital experiences by day, and spend my free time listening to podcasts, brewing coffee, taking photos, and tending to my garden.

I believe in making technology less complicated and more human. I focus on creating experiences that just make sense.

Core Competencies

Design Strategy & Leadership

I help organizations establish effective design processes and build high-performing teams. Drawing from my experience leading multiple design teams, I create frameworks for success, mentor designers, and ensure design solutions align with business objectives while maintaining user-centered approaches.

End-to-End Product Design

I guide digital products through the entire design process, from initial concept to final implementation. Using an iterative approach of research, prototyping, and testing, I create solutions that engage users while driving business growth. My focus is on building products that are both purposeful and delightful to use.

User Research & Testing

I drive design decisions through systematic user research and testing methods. By implementing structured research programs, usability testing sessions, and design workshops, I help teams validate their assumptions and create products based on real user insights rather than speculation.

Design System Development

I create and implement scalable design systems that unite teams and ensure product consistency. By establishing shared components, patterns, and guidelines, I help organizations work more efficiently while maintaining design quality across all touchpoints. These systems serve as the foundation for successful digital products.

Collaboration in remote and hybrid teams

I have extensive experience working in distributed product teams. I'm comfortable with async workflows, aligning across time zones, and setting up collaboration practices that improve visibility, accountability, and speed of delivery.

Work Experience

2023 – 2024

Lead UX Designer / External Consultant

I was brought into a project that required rethinking the UX and structure of a platform supporting daily operations across hundreds of pharmacies in Poland. I set up the entire UX process: discovery, onsite research, workflow mapping, and decision analysis. Based on this foundation, I designed systems for task management, returns and orders, and a centralized admin dashboard.

The result was a measurable time saving — up to one hour per day per pharmacy. For the organization, this meant operational cost savings and standardized processes at scale. I led the project end-to-end, collaborating directly with the development team and business stakeholders.

2023 – 2024

Senior Product Designer

At Timebook, I was responsible for the UX and structural design of a tool built for product managers. I designed modules that supported the entire product work process — from building Opportunity Solution Trees and decision-making to managing meetings, documentation, calendars, and tasks. The goal was to integrate all essential tools into a single application.

We were also the tool’s first users — testing new features in our daily workflows helped us identify gaps and iterate quickly. This led to faster development and better product decisions. We introduced Continuous Product Discovery as a team-wide standard and used Amplitude to inform design priorities.

I inherited an existing design system, audited and streamlined it, and expanded the documentation. I also introduced async collaboration practices (Loom, Figma, Miro, Timebook). We worked in a hybrid model with a distributed team (PL, UK, US, BY).

2020 – 2022

Product Design Lead

I led the design of a mobile app supporting people working in the gig economy. I was responsible for features like onboarding, financial dashboards, payments, and loyalty programs. I initiated the team’s migration to Figma, introduced Miro and Loom for daily collaboration, and Maze for usability testing.

One of the biggest outcomes was the redesign of the challenge system, which led to over 200% increase in user activity. The project was fully remote, and I worked with teams from Poland, Sweden, Turkey, and Ukraine. Beyond design, I also supported product direction and team operations.

2010 – 2020

UX Team Leader

I built and managed the UX team while eSky was still focused on the local market. As the business grew internationally, I defined the team’s structure, led hiring, and established daily collaboration routines with product and engineering.

Together with the team, I led ongoing optimization of booking and post-purchase flows — from landing pages to support paths. We worked with A/B testing platforms like Optimizely, combined with tools like Google Analytics and Hotjar, as well as regular usability testing, to inform decisions. Over time, we refined our approach to experimentation and made design choices based on measurable results. Later, I moved into a senior IC role where I focused on improving booking conversion through data-driven UX changes. I also worked on internal tools used by customer support teams to streamline issue resolution and reduce handling times.

2008 – 2010

UX/UI Designer, Product Owner

I started as a graphic designer and quickly took ownership of designing internal HR systems. In a small team, we developed a candidate management platform. Later, I was responsible for JobExpress — a startup aimed at competing with leading job boards in Poland. I owned the UX and product structure, led research and planning. The product gained initial traction and laid the foundation for my transition into large-scale product and e-commerce work.
