Founder & developer at Gymplify, with practical AI consulting through luther.ch. Based in Zürich, Switzerland.
I build web and mobile products, take them into production and keep improving them with real users. Gymplify is my main business. Alongside it, I help business owners and small teams build websites, apps and useful workflows with AI.
I founded, built and operate Gymplify, gym management software with branded member apps across web, iOS and Android. I own the work from product discovery and UX through architecture, development, testing, app-store delivery, customer support and daily operations.
The platform connects memberships, check-in, training plans, progress tracking and member messaging. It has been live since 2021 and has more than 4,000 registered users as of 6 October 2026.
AI-assisted workflows support implementation, debugging and iteration. Product decisions, testing and release quality remain my responsibility.

Since October 2026, I offer one-to-one guidance for business owners and small teams:
- Find a starting point: choose useful AI tools and a first step worth trying.
- Build together: work on your real website, app, prototype or workflow and learn as you go.
- Get unstuck: investigate technical problems, understand your project and decide what to try next.
We work by video call or in person. Your code, accounts and hosting stay in your name so you can take the project forward independently. Consulting is provided through Gymplify GmbH.

My work combines AI-assisted development, web and mobile apps, workflow automation, testing, deployment and technical support. I use tools such as ChatGPT, Codex and MCP integrations, drawing on a hands-on engineering and product background.
I also built and operate LimmatBuddy, a river companion across web, iOS and Android with live conditions, safety information, maps and routing. It reaches up to 400 daily users on sunny days.

My Swisscom employment ends in October 2026 as I focus on Gymplify and AI consulting. That experience spans cloud platforms, engineering leadership, automation and production operations.
My earlier work includes the Nuxt Firebase module, a legacy Nuxt 2 integration, and other Vue and Firebase tools. These remain part of my engineering background.
