Open Source Contributions

boa — Embeddable JavaScript engine written in Rust.

  • Led the EngineError::Panic migration — converting internal panics across builtins (array, string, regexp, proxy, promise, typed_array, generator, bigint, eval, intl, vm/opcode, module/source, object) into recoverable errors.
  • Built out WinterTC compliance — new boa_wintertc crate, migrating console, atob/btoa, structuredClone, queueMicrotask, timers, and more from boa_runtime.
  • Implemented safe wrappers: JsWeakMap, JsWeakSet, JsAsyncGenerator, JsGeneratorFunction.

omniqueue-rs — Queue abstraction layer for Rust (Redis, RabbitMQ, SQS, GCP Pub/Sub).

  • Expanded test coverage across the in-memory, RabbitMQ, SQS, and GCP Pub/Sub backends.
  • Fixed outdated README/doc code snippets and cleaned up backend configuration.
