## Work

- [Mach IDE](https://sanjudev.com/work/mach-ide/): A SwiftUI-focused interpreter and macOS IDE exploring near-instant previews without the normal compilation path. Private local prototype. Supports a subset of Swift and SwiftUI. Does not replace the compiler.
- [TokenSight](https://sanjudev.com/work/tokensight/): A local macOS menu-bar tool for passive Codex and Claude Code usage analytics. Local-only. Distinguishes exact server-reported totals from attributed estimates.
- [Esme](https://sanjudev.com/work/esme/): A private daily couple journal. One prompt, two private answers, a shared reveal, a saved memory. Not chat, not social, not therapy. Not on the App Store.
- [TinyTrack](https://sanjudev.com/work/tinyscale/): Public lead of TinyScale. A controlled founder/operator tool for checking whether a site's conversion events actually fire. Not generally available. Not a catalog of Tiny products.
- [Swift Build Accelerator](https://sanjudev.com/work/swift-build-accelerator/): A correctness-first research program for reducing Xcode build and edit-to-visible latency. Phase 0 is not an acceleration result. No public speed claim.

## Updates

- [First Mobile Game](https://sanjudev.com/posts/first-mobile-game/): I'm gonna try and create my first mobile game. Will be using Buildbox because I had already purchased it so I'll try to get some value out of it.
- [Custom build service on a narrow Xcode slice](https://sanjudev.com/updates/2026/custom-build-service/): Stock xcodebuild on Xcode 26.3 accepted a custom build service for one isolated SwiftUI Debug Simulator build, and this is not a speed claim.
- [Esme, a private daily couple journal](https://sanjudev.com/updates/2026/esme/): A private daily couple journal. One prompt, two private answers, a shared reveal. Not on the App Store.
- [Mach IDE](https://sanjudev.com/updates/2026/mach-ide/): A private macOS IDE with a subset SwiftUI interpreter. On 23 August 2026 it evaluated 289 of 397 Swift files.
- [TokenSight, AI coding agent usage analytics](https://sanjudev.com/updates/2026/tokensight/): A local Mac menu bar tool that reads coding agent usage from files already on the machine.
- [TinyTrack, first public slice](https://sanjudev.com/updates/2026/tinytrack-first-public-slice/): Founder dogfood of a sidecar that checks whether a named conversion event left the page in a real browser.
