I've worked on a diverse set of open source projects over the past 15 years. These days, I spend most of my open source time working in Rust.

Projects I started

• Askama is a type-safe compiled Jinja-like templating language for Rust. It aims to be user-friendly, reliable and efficient and is quite popular.
• Quinn is Rust implementation of the QUIC protocol (a modern TCP replacement), available with a low-level sans-IO API or a higher-level futures-based API.
• tokio-imap and imap-proto are a tokio-based IMAP client and base IMAP protocol library in Rust. imap-proto is used by both rust-imap and async-imap.
• template-benchmarks-rs maintains a suite of benchmarks and results for the most popular Rust template engines to verify performance of different engines.

Other Rust projects

• I maintain:
  • indicatif, a CLI progress bar library
  • bb8, a full-featured async connection pool
  • flamegraph, a simple cargo subcommand for generating flamegraph
  • rustc_version, a library for querying the compiler version
  • skeptic, a way to test Rust code contained in Markdown files
• I help maintain:
  • rustls, a pure-Rust implementation of the TLS protocol
  • trust-dns crates, an implementation of the DNS protocol in Rust
• I have contributed several features to Cargo:
  • Namespaced features (unfortunately still unstable)
  • Initial minimum supported Rust version support (RFC 2495)
• I have written two accepted RFCs:
  • Accessing enum variants through type alias
  • Adding traits to the edition 2021 prelude

Non-Rust projects

• rnc2rng, a RELAX NG syntax transpiler written in Python
• abna, a Python library to get mutation data from the ABN Amro bank site
• AreWeMeetingYet, a simple way to communicate times across timezones

Other work

• Contributed code to ring, rcgen
• I am a Gentoo Linux developer (though not very active these days)
• Used to be a committer on couchdb-python and Mercurial
