Story | How I got here

Engineering, craft, then building things of my own.

  1. 2011

    It started with a camera

    Photography was where it began. Near the end of my Mining Engineering degree, it led me to Photoshop, then Illustrator, and then to designing websites. I graduated in 2011 and kept going with design.

  2. 2013 – 2018

    From intern to professional

    At Nilmoon, an online store, I designed websites as an intern. Then Innotech, a product design company building websites and apps: that is where my professional career really began, with three years as a UI designer.

  3. 2018 – 2023

    Wallex, from day one

    I joined as the founding product and brand designer: logo, brand and the first version. For two years I was the only designer, and I built the design system. As Senior Product Designer I later rebuilt onboarding and the purchase flow, redesigned and automated support, and cut KYC from two days to five minutes. Read the KYC case study →

  4. 2023 – now

    My own studio

    I founded MonooFrame. 7+ products, with engagements up to 14 months, in logistics, crypto, steel e-commerce, AI journalism, AI security and banking credit. One of them, Geonosys, an AI-security product, went on to raise $2M in funding.

  5. 2026

    Co-founding Joiniee

    Joiniee began with one question: why do people do an activity alone, when others could find you and join you? It is now an iOS social sports app, live on the App Store. Discovering Claude AI changed what I can do: I can now take a product from a user’s problem to the finished app on my own, and ship it with my team.

  6. Next

    Deepening the theory

    I want to study the theory behind design at university, and then keep growing inside an international company.

Thinking | How I work

Behind every screen, four habits.

  1. A

    Simplify the journey first.

    Before I touch the interface, I look for steps that can disappear. Fewer steps beat prettier screens.

  2. B

    Design for the rules, too.

    Platform policies, regulation and edge cases are part of the product. I design for them from the start, not after a rejection.

  3. C

    Follow it through to release.

    A design is not finished until it is live. I work with engineers, and increasingly build myself, so what ships matches what I intended.

  4. D

    Learn from real people.

    Important decisions get tested with users, and I record what changed and why, so every choice can be explained.
