Alannah Byrne

hello there,

Hi, I’m Alannah.
I make messy, data-heavy products feel simple.

I design data-heavy, complex products for people who work in spreadsheets all day and deserve better. I untangle the problems, then design the flow with intent-based UI design systems.

Mobile-first growth

Steady engagement gains from many small A/B tested releases, rather than one big launch.

Systems that last

Two design systems built from scratch, adopted across product and engineering teams.

Engineers building with confidence

An AI pattern workflow that helps engineers ship consistent UI without waiting on design.

Simvia: a design system that answers for itself

I turned a platform built screen by screen into one structural system, then gave it a voice: an AI assistant that tells anyone what exists, and logs what doesn't.

46 documented patterns, 17 platform-wide rules and 7 page templates in ten days

the short version

How I work

  1. 01

    Untangle the domain

    I dig into the rules, data and edge cases until everyone agrees what the problem actually is.

  2. 02

    Prove it in a working prototype

    I test real logic with real people before anything gets built for good.

  3. 03

    Scale it through systems and people

    I turn decisions into design systems and habits so teams can ship without me.
