What I do.
I’m a designer, not a decorator. A product builder, not a picture maker. And a code shipper, not just a prototyper.
Set product direction
First I help you uncover the real problems worth solving. Then I work
with you narrow them down, prioritise initiatives, and shape the
solution. This creates more alignment with stakeholders and clarity on
what to do.
Crack design problems
I work end-to-end to design quality interfaces and build robust
systems: From ideas to visuals to the finished product. By prototyping
early and often we will ship quality software that people love.
Nail front-end implementation
I work closely with developers and write production-ready
HTML,
CSS, and
JS/TS. Together we improve
accessibility, performance, reliability, and durability — with delight
in key places.
You’ll ♥ working
with me if…
You want someone who takes ownership.
I don't need much oversight to do good work. I set my own
direction, manage my own time, and know when to ask for input. You can
trust me to build something (from scratch) and see it through.
You want to build great products.
Quality comes from iteration, not imagination. I help you make
the right trade-offs and get something real in people’s hands early.
It’s the best way to find out what works. A kick-ass half always beats
a half-assed whole.
You want to launch on time and on budget.
The best is relative to your constraints. Without limits,
there’s always a better version. That’s why I work with fixed
deadlines and budgets. When something needs to give, it’s the scope —
not quality.
