Senior engineer for AI applications: model integration, evaluation, workflow automation and the interfaces people actually work in. Ten years inside Roche, Credit Suisse, Swisscom and Migros, where a system has to survive audit, not just a demo. Most recently I built the marketing automation pipeline that runs my own operation.
Each engagement ended with a recommendation letter.
From an unclear problem to a working product people can understand and use.
Understand what people are trying to achieve, where work gets stuck, and where AI can help. Turn an unclear problem into a useful interaction, information structure and testable prototype.
Make it clear what an agent is doing, what needs a decision, and what can happen next. Design task assignment, progress, review, refinement and recovery so people stay in control.
Build web applications, dashboards and workflow tools. Combine frontend experience with AI-assisted development to connect services, test user journeys and improve the working product.
When should an agent ask a question? What can it do on its own? How can a person challenge the result? These choices shape the product. I connect workflow research, interaction design and working software to make them tangible.
Research, flows and prototypes expose friction before it becomes engineering cost.
Claude Code, Cursor, Copilot and Codex speed up implementation, review and iteration.
LLM UX, evaluation patterns and RAG workflows turn vague AI potential into reliable product behavior.
I designed and built a working environment for AI-assisted research and creative production. It brings agent instructions, tools, queues, review interfaces and durable records into a workflow I use myself.
Translate intent into a task, make progress and failures visible, and show where a human decision is needed.
Compare generated outputs, refine a direction and review the result before moving forward.
Preserve prompts, source references and parent-child history so earlier work can be understood and continued.
Self-directed product development, used in my own workflow. A practical source of learning about human-agent collaboration.
Technicians running high-precision diagnostic machinery needed captured knowledge, instantly reusable. I owned the assistant end to end: interaction design, evaluation frameworks, dataset curation and the human-in-the-loop gates that let a regulated team trust the output, plus the enablement programme that got staff actually using it. Regulated environment; details in person.
Built UI components used across the organisation, one, an e-signature cleaner, reduced support ticket load by 80%. Launched the new UI for subsidiary Neue Aargauer Bank. Trained the UI leads in each of the 14 scrum teams, so the work continued after my contract ended.
Redesigned the datalake platform, internal and external, and coded components in Vue.js. The "Direct to Error" journey prototype scored 89% CSAT and "Resource Viewer" 81% CES, those numbers were the build decision.
Led UI/UX for the mobile self-checkout feature, design system in Figma, click prototypes, usability testing, and improved onboarding analytics. Shipped with a 9% lift in core metrics.
Wallet, store and social feed for the Silver Studio app, onboarding flows, portfolio views, and payment journeys, with social mechanics competitive with Snapchat, Meta and TikTok.
Designed and developed mobile app and web interfaces for IP-TV, 4K TVs down to phones. Built the Teleclub subscription shop solo, live for a paying broadcaster. Won Lab Day 17.
Complete redesign of a social MVP, UX flows across notifications, chat, hangouts and profiles. Shipped; retention rose 120% after release.

I've designed and built inside Swiss enterprise teams for a decade, full engagements, several extended. I also maintain a small AI product that has run a rental business's guest communication autonomously since 2023.
My educational background combines business development engineering studies at Aarhus University with gymnasium studies in design and technology. It informs how I connect user needs, business goals and technical delivery.
