Hey 👋, I'm Marcin

I’m a technical product designer.

...briefly.

A decade of making complex systems make sense.

A decade of making complex systems make sense.

My career evolved from brand design to complex B2B and B2C systems. Today I work in a hybrid of Figma and the IDE: ideas start as frames, become working prototypes on production code built with agentic tools and heavy use of MCPs, and some have even landed as shipped PRs to Home Assistant's frontend. It's also why I love working with developers: we look at the same working reference instead of a static mockup.

My decisions start from UX best practices and proven patterns, the kind of instinct a decade of complex products builds, and then get tested against reality: interviews, usability tests, surveys, and behavioral data when it's available.

Currently I'm a Senior Product Designer at the Open Home Foundation, working on Home Assistant. My main focus is Automations and Intelligence: how people create and manage automations, and how AI fits into the platform. Beyond that, I contribute across the product, from UX audits to features that lower the barrier to entry.

In recent years, I worked in renewable energy on web SaaS applications for solar and wind farms.

Previously, I designed a WYSIWYG website builder and CMS at lastminute.com.

At the beginning of my career, I freelanced on numerous projects, some showcased below.

Throughout my career, I’ve gained experience across industries - and I’m open to exploring new ones.

Tool stack (AI)

Over the years, the tools have evolved and so have I.

My main tool to visualize ideas is Figma, though I tend to use a hybrid approach of using MCP back and forth with AI Agents to work also in a working prototype, or on production <code>.

My UX practice depends heavily on each project’s context and the company’s setup.

tl;dr

Generally, I try to be tool-agnostic and simply use whatever makes my work better and faster. This is especially true in the current age of ✨ AI.

Process and methods

There is no single process I apply to every project. Because shipping a product is a team effort, I adapt my approach to the project’s needs, available resources, and the people involved.

My responsibility is to make sure I have enough evidence to begin iterating with confidence, using the principles of design thinking.

tl;dr

I always push for as much end-user feedback as possible, and plan my work accordingly to the resources that are available.

Endorsements

After years of freelance collaboration, I’ve dedicated the last decade to bringing my expertise into the heart of corporate B2B and B2C teams.

About me

I grew up on computer games and building LEGO Technics, which developed in me a passion to create, appreciate good design and to constantly ask the question:
“How does it work?“

Today I use my passion to work with people and create meaningful experiences and tools.

Let's connect

I'am currently seeking new career challenges.
