Product design · usability engineering · working prototypes

Hi, I’m Gideon.

I’ve worked on clinical monitoring at Philips, lab workflows at QIAGEN, product systems at Syndigo and gaming tools at Nifty League. I also design and build my own products, including InvoiceRate.

Featured case studies

01 / 04PhilipsProduct design and usability engineering

I worked on bedside-monitor behaviour, safety scenarios and risk documentation for clinical and engineering review.

190M+ patients monitored / yearOpen case study

I work across research, design and implementation.

I lead product and design strategy, research, interaction design and design systems. When a static screen cannot show the behaviour clearly, I build a working prototype.

03How I work

How I take a product question through to a working prototype.

01

Start with the decision that needs testing

I start with the person using the product and the decision they need to make.

02

Make the rules visible in the interface

I map research, business rules and technical limits into flows that product, engineering and domain teams can review together.

03

Build the interaction when screens are not enough

I build prototypes when a static design cannot show timing, states or edge cases.

04Contact

Need help with a product that is hard to use or hard to explain?

Tell me what the product is, who uses it and what needs attention. I’ll reply myself.
