Seattle-based hacker, designer and researcher. PhD student at the University of Washington. I make tools that help people debug their programs more effectively.
Deterministic replay is a fundamental enabling technology for advanced developer tools. My dissertation work investigates deterministic replay in the browser: how to capture and replay web applications; affordances for navigating to relevant program states; and debugging tools that use past program states to explain behavior.
Dolos is a modern, low-overhead deterministic replay infrastructure for capturing web application behavior. Dolos is being upstreamed into the WebKit project.
Timelapse is the first user interface for capturing and replaying web application executions directly from the browser's developer tools.
Probes enable a developer to add logging statements to a live or captured execution while it runs. Time-indexed outputs are a scheme for indexing and seeking playback to text outputs such as console logging.
I am a reviewer on the WebKit project, with a focus on developer tooling. In my spare time, I have been upstreaming Dolos and other parts of my dissertation.
Servo is an experimental browser written in Rust that explores new ways to parallelize, decompose, and secure a rendering engine for web content. I prototyped the current layout subsystem (block/inline/text layout), and worked on many other things.
C3: a research infrastructure for extensible, type-safe web browsers. I wrote a rendering engine for inlines, blocks, floats, and tables in C#.
