Product design




Golem is an open-source, decentralised marketplace for computing power. It enables CPUs and GPUs to connect in a peer-to-peer network, enabling users to rent resources from other users' machines. As a UX/UI specialist, I was tasked to work on the user interface client that was meant to connect the requestors (Blender artists) with providers (all the users willing to share their computing power).

I started my journey with the app in the late product development phase and was tasked to improve its existing UX as a one-man army in 3 months before the official release date. Seems impossible, but in this time, I was able to propose the implementation of the most crucial changes based on:

  • Heuristic evaluation
  • Stakeholder interviews
  • Corridor tests and close cooperation with the development team.

After this intense beginning, I could start the proper product design process. I've started by IDI with defined requestors' target groups. And with a live product already online with a user base growing daily, I could gather constant feedback via the company's dedicated chat and close cooperation with the QA team.

What worked:

  • Improving main navigation and making it consistent throughout all the app screens allowed users to use the app more effectively.
  • Redesigning the wallet component from scratch using user stories and detailed user flows allowed the team to deliver the safer and easier-to-use tool.
  • Defining user personas and creating a constant feedback loop allowed us to incorporate improvements to the app in every release.
  • Making detailed task and subtasks lists, that informed users on the backend side of things, made the app more user-friendly in the complex world of decentralisation.
  • Identifying all the errors in the app that were not solvable on the backend allowed us to create helper guides and improved app usability.
  • Improving overall transparency in the app allowed the innovative and complex product to be understood by the users.

UX tools used:

  • Heuristic evaluation
  • IDI's
  • Observation tests via Google Meet
  • Coridor tests
  • Desk research

Design tools used:

  • Sketch
  • InVision
  • Illustrator
  • After Effects


Working for over 2 years on such a complex product was an absolute blast. Being able to meet the development requirements with the users' needs and combine it all in the application used on 3 different systems was challenging but very gratifying. More details about the app can be found in the "Usage" section in the official Golem Network documentation
