What I'm working on in 2026

• Yet another VS Code extensino to make my job easier at work
• Wrote an iOS app 100% with Claude Code that will use Ffmpeg+libx265 to convert videos on-device to H265
  • Something you cannot do natively on iOS without using a software encoder, which produces large file sizes
  • Very slow on iPhones, so turning this into a Catalyst app too so I can leverage the extra horsepower there
  • Useful for reducing video file sizes by up to 90% or more with no perceptible quality difference
    • iOS screen recordings are dozens of MBs, this cuts them down to 1-2 MB
• Hopefully I will use Claude Code to finish all my other side projects, like a receipt tracking app, and maybe start more

What I worked on in 2025

• Replacing my personal bash scripts with TypeScript Deno scripts
  • Had fun writing a script to parse MP4 file headers to check whether a video has the hvc1 tag
• Wrote a VS Code extension to wrap our^Tinder's CLI build tools in a GUI
• Wrote some userscripts to automate common tasks when creating or reveiwing PRs at work (gist)
  • My favorite is the one that generates a message like this with a keystroke, for pasting into Slack:

    [My small PR](url) `+4 -19` @required-reviewer-1 @required-reviewer-2
    

• Writing jailbreak tweaks for my Mac to fix some minor annoyances with macOS
  • Yes, you can write macOS tweaks!

My Favorite Projects

Jsum	A Swift Codable replacement that uses reflection to create types and map values. No Codable, no Macros—just runtime magic 🪄✨ let person: (name: String, age: Int) = try Jsum.decode( from: ['name': 'Bob', 'age': 25] )
FLEX	A popular in-app debugging tool, capable of almost anything you can think of, from exploring the view hierarchy to calling methods in real time.
Pastie	A clipboard manager for iOS that started as a jailbreak tweak, which I later turned into a full app. The tweak can be invoked from the keyboard in any app.
Receiptie	A receipt tracking app that uses OCR and AI to scan and organize your paper or email receipts for safekeeping. (Closed source)
