I’m a software engineer based in Germany specializing in cross-platform Swift development, data sovereignty and software security.
My focus is on breaking Swift out of Apple’s walled garden by building the foundational databse, security and infrastructure tools needed to run Swift Apps natively on Windows, Linux and Android. Swift is so much more than just Apple.

- Amethyst Vein:: A cross-platform, declarative database framework, supporting encryption, inspired by SwiftData. Built from the ground up for non-Apple (and Apple) platforms.
- KeyringAccess: KeychainAccess-like secure credential management for linux via the SecretService API.

I am currently shipping Vein 1.1 and soon starting to work on architecting a cross-platform, end-to-end encrypted data synchronization engine for Vein. If you or your team need seamless, secure data syncing across operating systems in Swift, let’s connect.
