02 / ABOUT ME

A builder.
Not a bystander.

NODAYSIDLEIndependent. Intentional. Always building.

A craft-driven engineering practice rooted in native performance and local-first architecture.

I design, architect, and ship production-grade software across macOS native environments, high-performance desktop runtimes, and resilient web services. I avoid disposable prototypes and roadmap hype: every project in the catalogue has one clear job, a reproducible build, and working code that runs directly on hardware.

My work focuses on transforming unstructured, ambiguous goals into deterministic software. From low-latency audio processing and on-device Core ML to custom desktop tools and spec-driven code synthesis, I build with high agency, deep respect for platform conventions, and strict privacy by default.

More from the atelier
/ 01

Ship Real Products

Finished tools over slide decks. If an application exists in the catalogue, it compiles cleanly, passes tests, and installs without a debug session.

/ 02

Native First

Build for the platform, not against it. Swift 6, AppKit, Metal, and Rust over heavy wrappers to guarantee instant responsiveness and zero memory bloat.

/ 03

Local-First by Default

User data lives on-device in local SQLite or filesystem storage. Cloud integrations are explicit opt-in enhancements, never architectural lock-in.

/ 04

Deterministic Quality

Spec-driven architectures, strict typing, and end-to-end automated validation ensure systems behave predictably across every execution.

03 / THE TOOLBOX

Right tool.
Real depth.
