Joseph Rafael F.

Programmer | Rust

I'm an open-source programmer looking to capitalize on his skill set. I specialize in Rust and I'm a regular contributor of bugfixes and features to various open-source projects involving the language. My expertise lies in low-level optimizations, the notable ones I did for the main rust-lang umbrella being: * Polly optimizer to rustc * Alternative aliasing rule (`#repr(transparent)`) to rust-bindgen * Well-received prototypes for fast-math floating-point optimizations I'm comfortable with `unsafe` Rust code and interop with C or C++. I've been coding since 2009 and have used various programming languages besides those two. Can probably pick up C#, Python, Java, Kotlin or Scala within a day or two if the situation calls for it. Recently did a non-trivial personal project involving the WebRTC standard and I would say I'm reasonably confident in my knowledge of: * Its underlying base protocols (DTLS, SRTP, and SCTP) * Congestion control algorithms * Video encoding involving H.264 and its transport
