Structure
I’m an IoT Software Engineer and also an independent developer building native software for iPhone, iPad and Mac, exploring better ways to use AI tools.

@endFour focused apps, built and shipped independently. Most of the work, including the apps themselves, is published as open source on GitHub.
struct RedSum: App// RedSum is a SwiftUI app. Not available in Objective-C.iOS 26.0+ iPadOS 26.0+ macOS 26.0+
A Reddit client that turns posts and comment threads into useful summaries. Read communities, ask grounded follow-up questions, compare research, and save what matters.
struct RSSum: App// RSSum is a SwiftUI app. Not available in Objective-C.iOS 26.0+ iPadOS 26.0+ macOS 26.0+
RSS articles, Reddit feeds, YouTube and podcasts in one clean reader. Get summaries, ask follow-up questions, and talk directly to the content you follow.
struct Vortex: App// Vortex is a SwiftUI app. Not available in Objective-C.iOS 26.0+ iPadOS 26.0+ Beta
A focused browser with tab management, reader tools, content blocking, a share extension, and AI-assisted page summaries.
struct Aiassistant: App// Aiassistant is a SwiftUI app. Not available in Objective-C.macOS 27.0+
A floating Mac assistant for summarizing, rewriting, translating, inspecting files, and asking follow-ups from any app.
I work mostly in open-source Swift and SwiftUI projects and apps. I care about direct, understandable software that solves a real problem without getting between people and their work.
Most of it is AI that runs on your own device, plus small Mac utilities I built because something kept getting in my way.
A selection of native tools and prototypes from my public GitHub work. Each project starts with a specific friction I want to remove.
Private, system-wide autocomplete built around local GGUF models, with app-specific controls and on-device context handling.
A fork of mkbula/HideMyData that extends local PII redaction with document summaries, grounded Q&A, Apple Intelligence model selection, and exports.
A privacy-first document workspace with local redaction, reversible placeholders, summaries, grounded Q&A, and on-device MLX models.
A native Apple-platform AI assistant with Foundation Models, Private Cloud Compute, cloud providers, local MLX models, summaries, and follow-up Q&A.
A private, searchable screenshot history with change-aware screen capture, on-device OCR, flexible text search, result previews, and match highlighting.
A menu-bar utility that maps a physical 3×3 trackpad grid to stable app shortcuts — a virtual Stream Deck under your fingertips.
Two trackpad gestures to lock focus on the current app or pin a live preview of a window while working elsewhere.
A menu-bar utility that keeps websites and live app windows visible in resizable always-on-top panels, with opacity controls and saved layouts.
A native menu-bar Reddit client with summaries, Q&A, media browsing, text-to-speech, and secure OAuth and Keychain configuration.
