I design trust into AI you can't fully verify.

For thirteen years I've designed interfaces where people had to rely on systems they couldn't check — black-box analytics, probabilistic data, now LLMs. I make those systems legible enough to trust, and correctable when they're wrong.

Ask Markerr: Designing an AI Rental Search Experience for People Who Want to Trust It, But Shouldn't Blindly

Ask Markerr gave Markerr a concrete way to demonstrate its AI product direction: how search could move from dense filters toward natural-language exploration while keeping evidence, correction, and user control at the center. Its value was strategic AI repositioning, not launched product impact.

Case study2025

Ask Markerr did not ship to real users. It reached POC/MVP stage and was demonstrated to partners and stakeholders as part of Markerr's AI roadmap. That distinction matters, especially in AI product design, where the gap between demoed and validated can be large.

Designing trust into a government-scale AI audit system

63%

Case study2017

I led the UX for an AI system that helped government auditors write complex legal instructions. By reshaping messy inputs and giving auditors full control to review and correct the AI's output, we cut writing time by 63%: months to hours. The system shipped, was adopted across teams, and won Best technology case in the public sector.

Two platforms, one product: B2B pensions for HR and brokers

Shipped two distinct platforms on shared data in three months. 100+ research insights anchored every priority call. The dual-platform decision, validated through research, prevented a single-product compromise that would have pleased neither audience.

Case study2022

B2B platform architecture and multi-surface workflow design for HR managers and brokers.

Ditching Spreadsheets and Empowering Financial Plans

The MVP wasn't just user-friendly, it tackled inefficiency. Manual updates? Slashed by 40%, freeing specialists for deeper client bonds. New recruits? Onboarded in 1 week, not 2, thanks to the platform's usability. Confused calls? Down 30%, as dashboards made financial plans crystal clear.

Case study2019

Fintech workflow separation and analytical surface strategy. Replacing spreadsheet-as-product behavior.

OUT

Trust is the shape of the whole interaction, not a badge added at the end.

Empathy and the drive to earn genuine trust are not values I added to my practice. They are the foundation it is built on. Everything else — the input architecture, the behavioral translation, the code proximity — comes after that.

When little is on the line, people over-trust fluent answers, so you add friction. When a lot is on the line, they're already skeptical, so you give them evidence they can check.

01

AI shouldn't earn trust through opacity

Trust is a design problem, not only a model problem. I reshape the inputs a model sees and give people the right to correct what it produces.

Craft lives in the failure states and the uncertainty

Not the happy path. I design for non-determinism, graceful failure, and correction flows before I design for success.

Ship close to code

I build high-fidelity interactive prototypes with AI-Assisted Coding. I stay through implementation instead of through static frames over the wall.

Borrow proven patterns across domains (Jacob's Law)

Users don't live in your product; they live in everyone else's. I reuse what they already know so the novelty budget is spent only where the AI genuinely breaks the paradigm.

I don't treat product design as a linear assembly line.

My approach relies on a proprietary framework grounded in problem-solution co-evolution: Parallel Trust Design.

By balancing Sensemaking (immersion, debate, and philosophical framing) in tandem with an executable Trust Design Toolkit, I use visual pattern-finding to bridge the gap between abstract strategy and concrete product actions. I don't wait for requirements to stabilize; I design to establish Calibrated Trust.
