I’m Mark Jumbombo, a UI/UX and product designer with 4+ years of experience improving digital products through user research, behavioural insight, and iterative prototyping. I take ideas from discovery to user journeys, wireframes, prototypes, and high-fidelity UI—then validate and refine based on evidence from usability testing and analytics. Across freelancing and contract work, I’ve supported healthcare and ecommerce experiences by translating research findings into clearer information architecture, navigation, content structure, and customer journeys. I’m comfortable collaborating with stakeholders and technical teams, and I use tools like Figma, GA4, Hotjar/Contentsquare, and AI-assisted workflows (including Claude) to accelerate exploration and support implementation with practical, user-centred design decisions.…I’m Mark Jumbombo, a UI/UX and product designer with 4+ years of experience improving digital products through user research, behavioural insight, and iterative prototyping.
