Jeff Hodsdon

iOS & Apple platforms — performance, build infrastructure, and the craft around them.

Engineer focused on how apps actually run — build times, launch, frame pacing, binary size — and on giving coding agents the runtime context to fix what they find. Two full Bazel conversions (90s → 30s builds), 9% off Peloton's binary, image-aesthetic filter pipelines at 60fps, and basset.dev: live Instruments readings streamed to the agent. Design-engineer roots — camera apps, interaction design, 17+ years since Digg, technical co-founder of Milk (acquired by Google).

Founder, Engineer

Basset

  • Swift
  • SwiftUI
  • Instruments
  • Performance
  • QUIC

— Ask the phone that has the bug. Runtime context so agents can do real quality and performance work.

  • Coding agents guess at runtime behaviour from source. Basset gives them the readings — CPU, memory, frame pacing, network, view hierarchy — from the device that has the bug.
  • Native Mac app that attaches to a live iOS app over simulator or cable, turns on 63 Instruments, and puts a coding agent in the window with everything it reads.
  • Ship the open-source SDK, then ask any device running your app to turn on instruments for the next few minutes. Readings stream back over QUIC as a capture the agent reads.
  • No account. Nothing leaves your Mac. brew install --cask basset-org/tap/basset-mac

Lead iOS Engineer

Ami

  • Swift
  • UIKit
  • Bazel
  • BuildBuddy
  • rules_xcodeproj

— Full Bazel conversion of a live iOS app.

Spatial social network founded by Shawn Fanning (Napster) and Andrew Frame (Citizen).

  • Converted a shipping Xcode codebase to Bazel with modularization and BuildBuddy remote caching. Main target 90s → 30s. App kept shipping weekly throughout.
  • Isolated feature modules build in 3 seconds — teams develop out-of-band of the main app.
  • Built a highly scalable chat UI on UICollectionView with performant dynamic message layout.
  • Metal orb effect — bloom, halation, drifting chromatic facets — with 30+ live on screen in a collection view at a steady 60fps. Profiled and optimized, not a one-off animation.

  • MCP
  • HTTP/3

— Self first iOS apps. When an app does not serve me, I build one.

  • Image-aesthetic filter pipelines running at 60fps in the live preview; film-grain engine underneath — per-pixel luminance diffing in Metal compute shaders, a 257-entry film LUT for midtone-accurate grain, 64³ color-cube emulations.
  • Newswire: autonomous Claude reporter agents gather, dedupe, and beat-classify coverage via MCP tools, surfaced in a SwiftUI + structured-concurrency app over HTTP/3 + MessagePack.
  • One Bazel-modularized Swift codebase across all of them.
