Product Development

I turn ideas into shipped products. Web apps, native apps, games — from concept to launch. You talk to one person. The same person who designs, builds and ships your product.

Fast and Reliable

I ship regularly — recent work includes a macOS app, a web platform and a browser game. Realistic timelines, honest updates, shipped when promised.

Quality That Lasts

Clean architecture, maintainable code, no shortcuts. I build things that work today and still work in five years — by solving problems properly instead of patching around them.

Technical Range

I've been building software for 25+ years, across the full stack and across platforms.

  • Web applications (Java, Spring Boot, PHP, JavaScript)
  • macOS and desktop applications
  • Browser games
  • Content management systems
  • Open source libraries and frameworks

Consulting

Beyond building products, I advise on the foundations that keep them healthy:

  • Digital sovereignty // migrating proprietary systems to open source alternatives
  • Linux server administration // running web and database servers, data security, TLS, backups
  • Quality assurance // automated testing (unit, integration, end-to-end)
  • Compliance // GDPR conformity, accessibility (WCAG) and SEO
  • AI-assisted development // using modern AI tooling to develop and operate software more efficiently

Technologies

  • Frontend // HTML, CSS, SCSS, JavaScript/ES6, Vue.js, Svelte, Bootstrap, jQuery, SVG
  • Backend // PHP (CakePHP, Craft CMS, Kirby, Redaxo), Java (Spring, Hibernate, Tomcat), Node.js
  • Databases // MySQL, PostgreSQL, Oracle
  • CMS & Shop // Craft CMS, Redaxo, Reboot CMS, FirstSpirit, TYPO3, Magento
  • Testing & QA // JUnit, PHPUnit, Cypress, Selenium, Puppeteer, automated E2E tests
  • Infrastructure // Linux administration, Docker, Podman, Git, REST APIs, TLS, PayPal, macOS, iOS/Swift
  • Methods // agile development, code reviews, AI-assisted development

Open Source

I maintain a portfolio of widely-used open source projects — from Bootstrap components to chess modules. See my Projects for the full list.
