Absa ยท Insurance ยท UX Research & Design

Activate โ€” Insurer of the Future

Digital insurance suite: motor, building, contents & all-risk

Traditional insurance meant paperwork, slow response times and phone calls. Activate rebuilt the whole experience for the digital lifestyle โ€” shown here in the claims journey prototype.

  • Seamless policy management, no paperwork
  • Telematics-based driving rewards & cashback
  • Real-time GPS safety & instant app-based claims
Absa ยท Banking ยท UX Design

Customer One โ€” Account Experience

Core banking account list & journeys

UX research and design on Absa's Customer One programme โ€” rethinking how customers see and move between their accounts. The prototype above shows the redesigned account list in motion.

  • Research-led journey redesign
  • Tested prototypes before build
  • Long-running engagement since 2018
FNB ยท Home Loans ยท Design Sprint

Home Loans Internal Systems

First design sprint โ€” the pyramid prototype

UX and front-end work on FNB's home loans internal systems, built with agile collaboration and rapid prototyping in Drupal, WordPress, Adobe XD and Balsamiq. This clip is from the very first sprint.

  • Sprint from problem to tested prototype
  • Internal tools that staff actually use
  • UX + front-end delivery in one
Momentum find-a-financial-adviser page designed and built by Wouter Kirstein
Momentum ยท Insurance ยท UI & Front-end

Momentum Digital Experience

UI design & front-end development

Crafting interfaces for Momentum that were both functional and beautiful โ€” including the find-a-financial-adviser experience above โ€” built in Angular, CSS3, LESS, SASS and HTML5.

  • Designed and built, not just handed over
  • Component-led, maintainable front-end
  • Live on momentum.co.za journeys

More products, more industries

Absa ยท Fintech

Stash โ€” Micro-investing

Lean UX blended with 5-day Google Design Sprints on SA's easiest investment app. Fixed the expired-card flow that silently blocked deposits, streamlined PIN resets and cash-out expectations.

Outcome: higher engagement, better app-store ratings, fewer support calls.

BMW ยท Manufacturing

Production Line Calculator

Financial systems design for the production line of the new electric Mini in China โ€” complex calculations turned into a usable tool for planners.

Via CyberPro/Isanqa, 2021.

Liberty & Deloitte

Service Console & Salesforce

Liberty Service Console, Welcome Pack and Salesforce journeys; Deloitte's Gratitude App, Toursure and Customer One in Salesforce โ€” research and design for enterprise-scale service.

Via DVT and direct engagements.

Fintech ยท Sprint

Investment App โ€” Card Flow

Diagnosed a silent revenue block caused by expired payment cards. One resequenced step made users investable before they invest โ€” and restarted revenue.

Outcome: measurable revenue recovery from one screen.

Insurance ยท Sprint

Insurance App โ€” 5-Day Sprint

Broke months of analysis paralysis with a lean Balsamiq sprint. First test failed โ€” that was the win. Users tripped on jargon like "third party" long before the clever features.

Outcome: from stuck-for-months to shipped-in-a-month.

Culture ยท Workshops

Corporate Values Murals

UBUNTU and SYNERGY โ€” monumental value murals painted by the teams themselves during Cowboy team building workshops, now permanent office centrepieces.

What it's like to work with me

Wouter is a talented UX designer with decades of experience, and he works with a momentum I've rarely seen โ€ฆ often delivering polished work the same day. His insights helped transform what was a fairly dry mobile app into something genuinely friendly and personable.

No one should underestimate the value that someone with Wouter's skill brings to a project. He pairs a calm, professional demeanour with real soul, both in the work itself and in the relationships he builds along the way. Ask him what he gets up to in his spare time; you'll see what I mean.
