Background

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.

My tech stack

These are the tools I use most often, though my stack varies by project.

  1. Sketch

    Figma

    How I use itEvery project starts here. I sketch low-fidelity concepts, test flows on rough frames and settle the layout before anything gets polished.

  2. Prototype

    Claude Code / Claude Design

    How I use itI research the problem, map flows and write specs with Claude, then turn the sketch into a working prototype with Claude Design and Claude Code.

  3. Review

    Cursor

    How I use itI open the code in Cursor to edit it by hand and review every change, in React, TypeScript and Tailwind. AI helps me read unfamiliar code and catch issues before it ships through Git.

  4. Systemize

    Storybook

    How I use itRepeated patterns become components with documented states, tokens and accessibility checks against WCAG 2.2, so design and code stay in sync.

  5. Measure

    PostHog

    How I use itAfter launch I watch funnels and session replays to see where people actually get stuck. What I find goes straight into the next round of sketches.

Product DesignerMy 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.

UI Design InternFramna (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.
