AI-native UI/UX designer and design engineer.

I design the interface, prototype it myself and direct AI agents to write the code. I gate what ships.

Simon Heikkila

Brisbane, Australia. Open to AI-native product design and design-engineer roles.

Clinician console with synthetic data: patient context on the left, an empty consult note in the centre, alerts on the right.
Design note 1

Consult note. The centre column, the full height of the screen. The clinical lead’s one hard rule: visible without scrolling.

Design note 2

Patient context. Allergies, diagnoses, labs, weight and medications stay in view on the left while the note is written.

Design note 3

Alerts and vitals. Risk flags and vitals entry sit beside the note, so current risk is seen while writing.

Clinician workflow prototype. Whole screen, synthetic data. The three markers open design notes.View full size

Selected work

Five pieces, each with my role and its current state.

Mortgage brokerage AI adoption: both owners now build with it

I set up the guardrails and hardened the intake app for production.

The principal worried a new page would “break the site”. I set up guardrails and an API into the CMS, so the team’s AI tools edit content directly, with checks and a human sign-off.

Outcome: The principal ships content changes himself, inside checks I set up. The co-owner built the first version of a client-intake app with AI.

Buyer Brief Builder: a guided brief that replaced a PDF buyers weren’t finishing

I designed and built V1 with AI agents in a day.

It offers quick and detailed paths and suburb help for unsure buyers. Deeper questions appear only when an answer needs them. The first pass was one long form, so I restructured it into the two paths.

Outcome: Its structure, flow and design language run in the client’s live workflow.

Summary only. Client work, details confidential.

Simble Forms and Bookings: I sent back anything that broke the system

I was product manager and Scrum Master for both products.

I coordinated three distributed development teams. I built a 343-symbol component library for Forms. Bookings had its own atomic library, built with the same discipline.

Outcome: I reviewed implemented interfaces in staging against the system. Anything that broke it went back.

Summary only. Systems design from before AI.

Kaikki task view: a task queue, a task with outcome, steps and context, and a triage panel.

Kaikki: knowledge and tasks in one place

I’m building it as my own product.

Agents triage each new input, add context and propose the next action.

Outcome: An active prototype, in development since December 2025.

Own product. Summary only.

More work

  • Mortgage platform contingency build

    The vendor owned delivery. I kept a parallel implementation from February and fed critical fixes upstream. When the vendor’s cutover failed, that work kept a production path open and the site launched.

  • Mortgage lifecycle automation

    Lifecycle email and CRM automation, running continuously since 2019. Pre-approval emails open at 54 to 59%.

  • Pitch decks and investor materials

    Pitch and investor materials supporting more than $32M in closed fundraising, including a fund that closed oversubscribed at $5.6M. Real decks are under NDA.

Agents write the code. I gate the product.

I coordinated three distributed development teams. I now apply the same delegation and review discipline to AI agents.

Compound feeds the next Frame.

  1. Frame

    I define the problem and what done looks like. For the Buyer Brief Builder, the problem was buyers not finishing a PDF brief.

  2. Build

    I dictate the outcome and the agents write the syntax. V1 of the Buyer Brief Builder took a day.

  3. Review

    I read what they make and gate what ships. The first pass was one long form, so I restructured it into quick and detailed paths.

  4. Compound

    What fails becomes a recorded dead end. What must stay true becomes a test or guardrail. At the brokerage, the principal’s worry about breaking the site became guardrails and a human sign-off.

Hiring for an AI-native UI/UX role?

Send me the brief. If it’s interesting to me I’ll do it, and if I’m bad at first I won’t stop until I’m great at it.
