A new product or application
I can help shape the first version, design the architecture, and build a foundation that can grow with the product.
Available for freelance projects and team collaboration
Backend systems, Android apps, web applications and websites
I am a full-stack developer. I build Kotlin and Spring Boot backend systems, native Android apps with Jetpack Compose, and web applications and websites with TypeScript, React, Next.js and Astro.
I connect interface, API, business logic, data and deployment into coherent solutions. I have been programming for over 5 years through self-directed, open-source and real-world projects.
How I can help
Support at different stages of a project
I can help with a first product version as well as the continued development of an existing solution.
A module, backend or integration
I can deliver a module, integration, application, or backend without requiring the team to guide every technical detail.
Developing an existing project
I can enter an existing codebase, clean up parts of the app, add features, and reduce the risk of future changes.
