Paul Hajj. Principal Product Designer. Multidisciplinary. AI-fluent. Sydney-based.
Working with
I'm curious by default, I have a bias for action and I'm inspired by simple design that dissolves complexity.
I pair scale-up velocity with enterprise discipline, I help validate ideas early so you build things that are lucrative and loveable.
I move fluidly between big-picture thinking and hands-on execution, helping mature design thinking and process without sacrificing speed.
I pressure-test direction, unpack the whys (or why-not), rapidly prototype POCs and lead experiments that enable fast, evidence-led decisions.
I advocate for simple, impactful design that doesn't break things, I involve tech early, respect systemic constraints and sweat the edge cases.
