Andreas Müller
Available for consulting — Rust & native-app engineering

Andreas Müller — I build native apps and the tools that ship them.

I help teams ship native macOS & iPadOS apps over memory-safe Rust cores (bridged with UniFFI), deep PostgreSQL & SSH tooling, and cargo/CI developer tools that make Rust development safer.

How I help

Rust cores for native apps

I move performance- and safety-critical logic into a memory-safe Rust core, bridged to Swift with UniFFI and shared across macOS and iPadOS.

PostgreSQL & SSH tooling

I design and build database and remote-access tooling — transactional-safe DDL, ERDs, SFTP and monitoring — native, fast and reliable.

Rust CI & developer tooling

I ship cargo and CI tools that make Rust development safer: dependency-impact gating, diff risk scoring and spec-drift detection.
