Peter Wilder Product & UX Designer

Open to senior product / UX roles · US, EU, Remote

I design complex products
until they feel obvious.

UX/UI & product designer for software where ambiguity has a price — expert tools, enterprise platforms, and the states real products can’t skip.

Selected work GIA Hamilton RKS Design Freddie Mac NomadNest

5+ years designing across regulated, technical, and high-context product environments — platforms used by experts, internal teams, and global institutions.

Specimen · Hamilton — settings, one token set / two themes Shipped
Hamilton lab-automation settings screen shown twice — identical layout rendered in dark and light themes from a single token set.

01One token ladder drives both themes — no per-theme overrides survived review.

02State parity: hover, focus, disabled, and error verified across both renders.

03Density held at instrument scale — the same 8-px rhythm both sides of the split.

What I actually do

  • I don’t just make screens.
  • I define what the screen needs to prove.
  • I structure the flow before styling the surface.
  • I design the states most portfolios crop out.
  • I document decisions so engineering doesn’t have to guess.
  • I revise when evidence beats preference.

Every state. The whole job.
Most portfolios ship the left. The work is the right — the empty, loading, and error states a real product can’t crop out.

Eight states, every component: default · hover · focus · active · disabled · loading · error · empty.

Four contexts. Four design muscles.

Four engagements, each proving a different muscle — in-house expert systems, enterprise UI at scale, agency end-to-end, and founder-led product. The range is the thesis, not an accident of who was hiring.

The shape of the work.

Five years, five operating contexts. The question a portfolio this varied has to answer is whether the range is a thesis or a drift. Two views — the arc it followed, and the ground it covered — answer it.

Eight engagements, one continuous line — founding team to agency to in-house to a venture of my own. The trajectory is deliberate: each context was chosen to learn what the last one couldn’t teach.

The coverage matrix 8 engagements × 3 contexts
  • Full case study
  • NDA / concurrent
  • Covered
  • Not covered

Every operating context, covered at least once. Four engagements documented end-to-end as full case studies. Range you can audit — not just claim.

Principles earned under constraint.

Five positions I’ve defended in rooms where agreeing would have been easier. Not taste — conclusions, each with the project that taught it. Open any one for the reasoning.

Research reshapes the problem, not just the solution.

RKS — discovery inverted the brief; I restructured the IA around visitor intent.

What one interview cost

I’ve thrown away a month of design work because one interview revealed I was solving the wrong thing. Research that only confirms what you already believe isn’t research — it’s decoration. The reversal never happens if it’s scoped as a validation step.

If users notice the interface, the interface has failed.

Unreleased product — iterated a reply affordance until zero test participants missed it.

When a pause is a defect

When a participant pauses before acting, that pause is a defect. My first treatment was visually minimal because I’d optimized for hierarchy; one in four people missed it. The version that tested clean was not the one I’d have shipped on intuition.

Evidence outranks preference — including mine.

Hamilton — two treatments I argued for were cut once the render cost was measured.

Setting my own work aside

I’ve set aside work I was proud of because the data was unambiguous. It never gets easier and it’s always the right call. Preference has no standing in a decision once there is evidence pointing the other way.

Constraints, taken early, sharpen a design.

Hamilton — a WPF rendering limit became the filter the visual system was built through.

The case for early limits

A constraint met in sprint one produced a more disciplined system than a blank canvas would have. Treated as a late-stage blocker, a constraint forces compromise. Treated as a first-order input, it produces the design you wouldn’t otherwise have reached.

The handoff is part of the design, not cleanup.

GIA — ran sprint ceremonies while designing; watched what every vague annotation became.

What an open handoff costs

Engineering fills whatever the handoff leaves open. A missing edge case becomes a bug; an undocumented loading state gets invented by someone who didn’t design the component. A handoff should leave no decision the designer would have made differently than the person building it.

How ambiguity becomes interface.

The same path on every engagement — an unclear problem resolved into a built, documented interface. Not handed between people; carried as one continuous process.

  1. Unknowns

    Name what the team can’t yet answer.

  2. Evidence

    Interviews and testing aimed at the riskiest assumptions.

  3. Structure

    Information architecture and flow before any surface.

  4. Interface

    Layout, hierarchy, and the system that holds them.

  5. States

    Empty, loading, error, and edge cases — designed, not assumed.

  6. Handoff

    Annotated specs that leave no decision to guess.

  7. QA

    Built result checked against the design intent.

Research

Competitive landscapes read for the decisions behind them, not the features. Interviews that listen for what people don’t say. Usability testing aimed at the work I’m most attached to — that’s where the useful surprises are.

Design

Tokens, states, and edge cases decided before the showcase view. Flows that hold under real data, not demo data. The work is done when an engineer could build it without asking a question the design should have answered.

Delivery

I’ve run sprint ceremonies while designing, so I scope for what production actually does with a spec. The handoff is annotated, walked through, and treated as the last design decision — because it is one.

Where I’m strongest.
