Privacy-first family location and safety app for iPhone, Apple Watch, and CarPlay.

• Built a live diagnostic uploader and internal triage dashboard, then used it to trace a production CloudKit permission bug affecting every family joiner.
• Shipped crash detection, SOS, medical ID Live Activity, trip guidance, and on-device translation with emergency-specific safeguards.

Native macOS render studio for cinematic product shots — custom Metal engine, keyframed camera moves, 4K/60 export.

• Extracted the custom Metal LiDAR point-cloud engine built for RANKAN and re-aimed it at product cinematography: procedural 3D devices, eight cinematic scenes, depth of field, volumetric weather, and one-click App Store screenshot batch export — 18K LOC of Swift and Metal with no third-party engine.
• Shipped v0.1.0 through v0.3.0 in 34 hours from first commit as a Developer ID-signed, notarized DMG with license activation; the studio renders its own marketing showreel headless.

Zero-install peer-to-peer delivery network for Blue Springs, MO — live at brykk.app/local; drivers keep 100% of every fee.

• Re-aimed BRYKK's live-location relay at local commerce: browser-only ordering where the order link is the account, 3-second live driver tracking with 30-meter arrival detection, web-push driver dispatch, and atomic first-claim-wins order assignment.
• Planned June 10, in production June 11 — Next.js + Supabase + Redis with privacy-scrubbed ephemeral tracking, a service-area geofence, rate limiting, and an operations console for driver approvals and dispatch.

Golf companion with live website plus iPhone and Android beta builds for matching golfers and turning chat into rounds.

• Built with Jaret Priddy around golfer discovery, matching, open games, match chat, round proposals, nearby course search, shared scorecards, and a driving-range tracker.
• PinPalsGolf.com is live; iPhone and Android beta builds are both in testing with near-feature parity across all three surfaces.

Free local continuity layer for AI-assisted work — Claude, Codex, durable project memory, and reusable context packets at fob.sh.

• Built the local CLI plus browser dashboard, durable file-backed project memory, multi-model routing, context packets, and saved-decision/handoff flows used across Claude Code and Codex.
• Shipped as a local-first product with a public marketing site on Vercel; the engine stays on the user's machine instead of becoming a hosted dashboard.

Open-source CLI that redacts code before it reaches an LLM, with test-verified obfuscation and a repo-governed policy file.

• Authored a Python and JS/TS redactor (stdlib ast + tree-sitter byte-splice), a .cloakpolicy YAML governance layer, pre-commit hook integration, and an obfuscate --verify mode that fails the operation when the user's own test suite fails.
• Released v0.3.0 on PyPI under Apache 2.0 with Trusted Publisher OIDC, branch protection, ruff/mypy --strict clean, and CI green on Python 3.11/3.12/3.13. Designed as the OSS sibling to Fob.

Multiplayer IDE and conversion platform for Swift ↔ Kotlin ↔ TypeScript.

• Built real-time collaboration, lock management, billing, and multi-tenant workspace infrastructure around native-code conversion.
• Used it in production to ship GoKC to both iOS and Android as a solo engineer.
