A little about me

My work connects research with practical product decisions across enterprise B2B software, banking and digital services. A background in product and systems design engineering helps me make complex processes easier to navigate.

I work from early problem definition and customer research through interaction design, detailed UI and working prototypes. I’m particularly interested in AI experiences that reduce manual work while keeping people informed and in control.

What I’ve worked on

Enterprise workflows — supplier management, data quality, banking and digital services.

AI experiences — guided actions, document extraction and reviewable automation.

Research & direction — customer interviews, usability testing, product strategy and design mentoring.
