I’m a self-employed software engineer from Switzerland 🇨🇭, running
👉 zwei und eins gmbh — where I help companies and IT teams build and simplify web applications.

My current focus:

• Reducing complexity in existing web applications
• Backend & application architecture
• Identifying and removing unnecessary SPA / API layers
• Server-driven, hypermedia-based systems (Datastar, SSE streaming, events, HTML APIs)

If your web application is costly to maintain and increasingly complex, I help remove unnecessary complexity — so it becomes stable, understandable, and cheaper to evolve.

Most of my work is private client work — this profile shows selected open-source projects and experiments.

The tools obviously matter less than the outcome — clarity, simplicity and long-term maintainability.

• PHP (async w/ Swoole, Mezzio, Slim, Twig, DI, JWT, strictly typed), occasionally Go and Python
• Databases: MySQL/MariaDB, SQLite
• Frontend: ES6 / TypeScript, HTML, CSS/Sass (Bulma, Open Props)
• Build & tooling: ESBuild, phpstan, php-cs-fixer
• Approach: server-centric, streaming, minimal client state (Datastar, SSE)

I occasionally touch React or Vue or other SPAs — but usually when migrating away from them 😉.
