// HOW I WORK

Senior enough to lead. Hands-on enough to make.

01

Find the real problem

Research, stakeholder alignment and evidence turn ambiguity into a useful brief.

02

Make thinking visible

Flows, prototypes and workshops create shared understanding before teams over-invest.

03

Design for delivery

Accessible interfaces and scalable systems are shaped with engineering, not handed over to it.

// THE SHORT VERSION

I bring calm, clarity and momentum to complicated product work.

more about me ↗

I'm Marlon Bunday, a senior UX/UI and product designer with 25+ years helping organisations untangle complex digital products — from regulated sectors such as insurance and healthcare to enterprise data platforms and multi-brand consumer services.

I work best where the problem is genuinely hard: legacy systems being reinvented, multi-stakeholder products with competing constraints, or regulated environments where clarity is a compliance requirement, not a luxury.

I connect user insight with commercial and technical reality. I'm calm in ambiguity, articulate with non-design audiences, and I believe the best design decisions can always be explained simply.
