Design, engineering and product are one conversation when there is nobody to hand off to. Three of these I built alone, and WhatWeCook with Firuze and David. One of them went from a sentence said out loud to a merged feature in six minutes, and from restart to App Store review in 32 days.

A journal for the people who lead, with a coach who has read every entry.
Seventy thousand store associates at 80+ brands in 40+ countries, and omnichannel features behind a 30% increase in store revenue for retailers. I led the design and the teams built them, which is a different verb and the reason the numbers are this size.
The till leaves the counter, so a sale finishes wherever the conversation is. VEJA trains a whole team on it in about two hours.
Look closerOne view of an order that merchandising, operations and customer service can all argue in front of. 12,000 people at head office open it every month.
Look closerThe whole website rebuilt, workshop to launch in eight months, written by the design team.
Look closerThose three are what I can show you here. What they add up to, the five areas of the store they cover, the numbers the retailers report and what the associates holding it say, is the whole nine years in one piece.
We wanted to take a card on the phone itself and the hardware would not allow it, so we designed around it and filed for it: the customer’s phone and the associate’s phone authenticating between themselves. Granted as US 11,379,813 B2, to NewStore, five inventors, me among them. Apple announced Tap to Pay on iPhone in 2022.
Our clienteling already ran on SMS, so we proposed the same thing over Apple Business Chat: find a shop in Maps, message it, and talk to an associate standing in it. Apple never took Business Chat far. The work was real.
The patent was filed in January 2018. Apple announced Tap to Pay on iPhone in February 2022, and NewStore shipped it to retailers that September, among the first to do it. What that is worth is for you to decide; the dates are public and so is the patent.
Signum+ came straight out of my master’s thesis and became the first thing I made that people paid for. What’s Next? was the first run at the idea WhatWeCook finished five years later. Neither has a page here; both are why the rest of this one exists.

A cooking diary that remembered what you had made and recommended the next one from your own meals. Ruby on Rails, and the first run at the idea WhatWeCook finished.
A digital signage system that came straight out of my master’s thesis. The first time I turned my own research into something people paid for.

Nobody can write this part of a portfolio themselves. People who reported to me, hired me, sat across from me and watched from outside, quoted in full rather than cut to the flattering half.
“He isn’t a typical design or UX lead. He can comfortably think like a product person, and is really on the cutting edge of generative AI and codegen, as his team all are too.”
Benjamin HoskinsChief Technology Officer, NewStore“I learned so much from his empathetic and transparent leadership style. He created a space where feedback and ideas were valued, and that made a big difference for the team’s growth.”
Sarah den BoerProduct Designer, reported to Henning“He has a rare ability to zoom into the smallest design details while simultaneously steering bold, strategic bets. A real superstar player-coach.”
Mitun PandeyDirector of Product Operations“He builds design culture, influences how teams think, and helps shape the way we work. He is a builder, a mentor, and someone who always shows up with a strong sense of purpose.”
Phil GranofChief Marketing Officer“We collaborated on a Continuous Learning strategy that brought fresh user insights straight into the product, resulting in clear, measurable improvements to the user experience.”
David HawdaleSenior UX Researcher, reported to Henning“The best design leader I have ever worked with. He has the Midas touch to make everything sharper, clearer and more impactful.”
Scott MatzaHead of Product“His ability to drive UX strategy, lead with empathy, and build a cohesive design team made a huge impact on our product work.”
Jose MartinHead of Engineering“He consistently pushed the limits of what his team was able to accomplish, always learning and sharing his knowledge to improve those around him.”
Levi BaadeProduct and Technology Builder“He does not limit himself to his immediate scope. If he sees something that could be improved he steps in and takes initiative without fanfare, and he plays an active role in shaping the culture of the company.”
James LunanSolutions EngineerI took over a design function with no designers left in it and rebuilt it: research, content and communication design alongside product, all on one levelling framework, with research every six weeks whatever the roadmap was doing. Customer satisfaction went up and handoffs to engineering got smoother. That half of the work ships through other people, which is the half a portfolio usually cannot show.
