Aura — Giving Agentic Development a UX Conscience

As product managers and engineers began building through agents, the old design handoff lost its place in the workflow. I built Aura to bring UX reasoning into that workflow, with explicit review scope, maintainable rules and human decisions where they matter.

When the Database Starts Designing the Product

An operational monetisation product exposed the logic of its backend to its users. My team and I raised the implications for navigation and control, including the need for alerting. This case examines product judgment under constrained decision rights, with identifying details omitted.

Modernising a National Platform You Do Not Control

vr.de had just relaunched, yet much of it had not quite made the journey to mobile. The real challenge was larger than responsive design: turning tight CMS constraints, long release cycles and a crowded stakeholder map into an executable modernisation programme.

Sales Landing Pages — From Behavioural Evidence to Better Conversion

The landing pages attracted substantial traffic but converted just 0.8% of visits. I used behavioural and commercial data to rethink the page structure, followed by a staged rollout and further experiments. Reported results included 2% conversion and an 8% increase in gross revenue.

Twelve Companies, One Shared Product Logic

Design System Strategy — Scaling, Migrating, Still Shipping

A shared component system supported several products as the engineering team grew. I built its design foundation and helped carry it into MUI, balancing continuity for users against the maintenance cost of owning every component ourselves.

Evidoxa — Testing a Product Idea in Humanities Research

Historians described a need to organise sources and relationships without first becoming database specialists. I developed the idea into a working MVP, using the prototype to explore how a flexible data model could fit the routines of research. Validation in sustained research use is the next step.
