I build products for work, knowledge, and play.

I built capture, sync, and search, including Share Extensions, voice recording, and native collection views.

SQLite FTS5 and local embeddings power search, with excerpts explaining each match. An optional reader service fetches public links.

A structured document map supports reference and number checks. Local language models handle contextual review and writing assistance.

I built the editor integration, reusable Swift packages, and review evaluations. Each finding links back to the document.

I built exchange-data processing, alerts, watchlists, subscriptions, and notifications. Detectors track state changes and cooldowns to control repeated alerts.

Shared services evaluate signals and backtests, keeping results consistent across native and web clients.

I built the SwiftUI workshops and RealityKit world around a custom brick-placement solver. Stud-and-socket matching, collision checks, and validated assembly steps power free-form creation and guided builds. Articulated characters and vehicles bring those creations to life.

Mesh batching and caching handle detailed models while preserving moving joints and detachable assemblies. Versioned local saves, atomic world updates, undo, and recovery checkpoints keep creations and progress intact as players build and travel between places.
