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. I built a Firebase backend to retrieve content from saved links.

I connected the document engine to SwiftUI editing tools and reusable Swift packages for writing and review. A structured document graph tracks terms, references, dates, and amounts. Dr. Word combines rule-based checks with model review, links findings to source paragraphs, and previews suggested changes before applying them.

Writing assistance runs on-device through Apple Foundation Models or downloaded Gemma models via LiteRT-LM. Protected text spans help preserve names, numbers, and references during rewrites and proofreading.

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. I built a Supabase backend to track spending of consumable in-app purchase credits.
