I design software that invoices €180M a year (Mainteny), cuts handling time by 39% (Kiwi.com), lifts conversion to the 30s % (Musosoup) and covers 2,100+ destinations (BOVA).

10+ years making complex workflows faster, measured in revenue and time saved. Front-end developer by origin, so what I design ships.

What clients and colleagues say

From founders, a VP of Design and product people at Mainteny, Musosoup and Kiwi.com.

Over the years, Marko became our design partner.

… He always challenged whether something was really needed before we built it, which kept the product clean and simple even with so many new features. … I can fully recommend him to any company building a complex B2B SaaS product.
