01. About me

I have been working professionally with web technologies since 2007. For about half of these 15+ years, I have worked as primarily a back-end developer, and for the other half as a full-stack developer. This mix of experience makes me particularly suited for projects that require intricate business logic, but also a good eye for interface design and user experience.

Check out my projects page for a list of some of the stuff I have worked on.

02. Specialities

During my time as a dedicated back-end developer, I have worked heavily with system architecture, APIs, testing, Domain-Driven Design, payment system integrations, and more.

These are all areas in which I can offer my expertise, and in combination with my intermediate front-end knowledge, I can help you with full-stack projects such as initial prototypes, custom administration panels, and implementing whole new features to existing applications.

See my services page for more information.

03. Technology Preferences

My primary competency is back-end development with PHP, .NET (C#) and Node.js. On the front-end side, I mainly use TypeScript and Vue.js.

Here is a list of my most used frameworks and libraries:

PHP: Laravel, Symfony, PHPUnit
.NET: ASP.NET Core, Hot Chocolate, XUnit
Node.js: Electron, Tauri
Vue.js: Nuxt.js, Vite, Pinia
