About me

Samuel Oldmark

Product Designer

Stockholm, Sweden

Who I am

I design calm, high-trust experiences for complex products.

I focus on turning high-stakes product complexity into clear decisions, clear interfaces, and shipped outcomes.

Trust-critical productsUX + UI + FrontendOpen to new roleProblem framing to shipped UIFast, decisive executionReact / TypeScript / Tailwind

I'm Samuel Oldmark, a product designer based in Stockholm focused on digital products where trust, clarity, and usability directly impact business results. I design end-to-end experiences across web and mobile, from problem framing and user flows to interface design and shipped implementation.

I currently run my own agency, Oldmark Studio, where I work with multiple clients across different sectors. My work spans UX and UI design, design systems, websites, digital products, frontend development, and AI-assisted solutions. Working across varied projects has made me comfortable taking broad ownership, adapting quickly, and turning early ideas into polished, working experiences.

I'm currently looking for a product design role where I can lead meaningful product work, raise design quality, and help a strong team ship better outcomes.

A word from collaborators

“I have worked with Samuel for a little over a year and he's extremely professional and has a very keen eye to detail. He also comes up with creative yet very practical ways to solve UX issues and has the user in mind while doing so. Samuel is also very flexible in accommodating changes and also very agile in coming up with alternative solutions when one solution doesn't work. He's an asset to any organization and will contribute immensely to them.”

Experience

Oldmark Studio

Founder & Product Designer – Oldmark Studio

May 2024 - Present

I run my own agency, Oldmark Studio, where I work with multiple clients across different sectors. My work spans UX and UI design, design systems, websites, digital products, frontend development, and AI-assisted solutions. Working across varied projects has made me comfortable taking broad ownership, adapting quickly, and turning early ideas into polished, working experiences.
Hälsa+

Product Designer – My Medical Data | Hälsa+

Jan 2025 - Apr 2026

I worked as a product designer at My Medical Data, where I designed and planned a new mobile app called Hälsa+ focused on health. As the only designer on the team, my role was to provide UX and UI solutions while also acting as a bridge between development, design, and stakeholders. When I joined, there was already a demo app built from scratch, but it had room for both UX and UI improvements. This experience was very insightful, and I expanded my skills by taking on new tasks and challenges that I hadn't faced before.
Framna

UI Design Intern – Framna (earlier Bontouch)

Nov 2023 - May 2024

I completed my five-month internship at Framna (earlier Bontouch) in Stockholm two months ago, which was a part of my education. My main focus was on UI design, though I was also involved in UX work. During my internship at Framna (earlier Bontouch), I had the opportunity to work with a real product and participate in client meetings. I collaborated with experienced designers and developers, gaining a deeper understanding of all aspects related to a digital product, as well as how collaboration between different skill sets can be executed.
