A new basis for open, interoperable, decentralised, end-to-end encrypted, real-time communication.

I currently work on the Matrix Rust SDK 🦀.

Wasmer is one of the major and leading WebAssembly runtime out there.

I have co-founded this project, and sadly left it. I've greatly contributed to the runtime itself:

• Worked on 3 compilers: Singlepass, Cranelift and LLVM,
• Worked on the 3 engines: JIT, shared object file, static object file, and the VM core,
• Worked on the public API, documentation, examples, well… everything!

In addition to the runtime, I have created many bindings:

• wasmer-c-api is the C embedding for Wasmer,
• wasmer-python for Python,
• wasmer-go for Go with its post: Announcing the fastest WebAssembly runtime for Go: wasmer,
• wasmer-ruby for Ruby,
• wasmer-php for PHP with its post: 🐘+🦀+🕸 php-ext-wasm: Migrating from wasmi to Wasmer,
• wasmer-java for Java with its post: Announcing the first Java library to run WebAssembly: Wasmer JNI,
• wasmer-postgres for PostgreSQL with its post: Announcing the first Postgres extension to run WebAssembly.

Notable fun projects I did there:

• sonde-rs is a library to compile USDT probes into a Rust library,
• llvm-custom-builds is a sandbox to product custom LLVM builds for various platforms,
• loupe is a set of tools to analyse and to profile Rust code,
• inline-c-rs, to write and to execute C code inside Rust,
• and much more.

Automattic is the company behind WordPress.com, Tumblr, WooCommerce, JetPack, Akismet, Simplenote, Longreads, Gravatar etc.

One notable open source project I have worked on is a parser for Gutenberg, in Rust, that compiles to many targets: WebAssembly, C, PHP, Node.js etc. It led to a blog post series: From Rust to beyond.

It is a set of modular, extensible and structured set of PHP libraries; aiming at being a bridge between industrial and research worlds. More than 165 millions installations, but projects are archived after 15 years of joy.

My wife and I have built a self-sufficient house, made of straw, wood and earth. This repository contains all the program I'm using for the home automation. But the most important readings are at lamaisonvivante.blog, our blog describing our adventure!
