I'm Daniel Ehrenberg (he/him or they/them) and have worked as an engineer working in various standards bodies, to improve JavaScript, WebAssembly and the Web Platform. I want to make computers more open and easy to program for everyone.
I most recently worked at Bloomberg as a software engineer. Previously, I worked at Igalia, an open source consultancy, which counts Bloomberg among its clients.

To learn about my work, you can watch some of the talks I've given about it. I like to give talks in various groups of JavaScript developers, to explain how TC39 works, encourage people to get involved, and learn more about different developers' needs. (Note: there were more talks and podcasts since these, just search YouTube for my name. also an ACMQ publication.)

I've worked on a number of proposals in TC39, the JavaScript standards committee, including:
- Finished standards (Stage 4):
- BigInt: Arbitrary-precision integers in JavaScript
- Class fields and private methods
- RegExp features: named capture groups lookbehind assertions, Unicode property escapes
- WeakRefs: Weak references and finalizers
- Top-level await: Asynchronous module evaluation
- Late-stage proposals (Stage 3):
- Import assertions and JSON modules: Support for multiple module types in JS
- Realms: Multiple isolated but synchronously interacting globals in JavaScript
- Temporal: New date/time library built-in to JS
- Earlier-stage proposals (Stage 1-2):
- Records and Tuples: Immutable data structures
- Decorators: Extensible classes
- Module fragments and module blocks: Inline modules in JavaScript to improve bundling and Web Worker deployment
I've also worked in other areas of standards, including:
- ECMA-402 (
Intl): Organized subcommittee and championed several feature proposals - WebAssembly:
- Edited the initial WebAssembly JS API and Web API specifications
- Created the WebAssembly BigInt integration proposal
- Edited the WebAssembly ESM integration proposal
- Going forward, I'm really excited about the Wasm GC proposal but haven't managed to help much yet
- HTML (e.g., integrations of TC39 proposals)
- WebIDL (e.g., formalizations)
In a past life at Google, I worked on Linux kernel/firmware stuff to improve access to SSDs. As part of that, I wrote a popular introduction to Linux AIO and even landed some very basic upstream kernel patches.
