I am one half of DevRel (developer focussed aspects - node operation is maintained by the other half of the team) and do integrations for the mixnet project Nym.

A lot of my work now is on what DevRel looks like in the age of LLMs: docs and SDKs built so that an agent, and not only a person, can carry an integration through with as little friction as possible.

Current work centres around:

Recent work, newest first:

  • A scenario suite for the docs-as-agent-surface, checking that an agent working only from the docs states Nym's limits instead of agreeing with whoever is asking
  • An MCP server for the docs, so a coding agent can search the docs and the Rust source and read live network state; retrieval runs off a static index built at deploy time, with no vector database to operate
  • Restructuring the network docs around an explicit threat model: adversaries split by vantage point, the linkage vectors that attribute traffic, and the unlinkability properties each configuration is measured against, with a decision path from use case to configuration
  • mix-* family of Typescript SDK libraries (drop-in-ish fetch and websocket Mixnet abstractions for WebView-based apps + private DNS resolution)
  • crates.io preparation and publication flows for majority of the Nym monorepo crates
  • nym-smolmix Rust crate, and nym-smol-core, the userspace smoltcp stack underneath it
  • Rust SDK stream module (MixnetStream, AsyncRead/AsyncWrite over the mixnet) + IpMixStream, which layers the IP packet router on top of it to reach clearnet
  • Debugging WASM runtime errors and multiple (Go + Rust) runtime interaction for mixFetch + modifying its concurrency restrictions
  • Implementing the Diataxis framework for the Nym docs

Main focuses:

  • System programming with Rust (especially focussed on tunneling/networking abstractions)
  • Using WASM for privacy-preserving code within the confines of browsers (e.g. userspace TCP/IP, certs, and security restrictions)
  • Documentation, including making it readable by agents as well as by people

Note on Git commit heatmap: since we use squash-and-merge for PRs, the majority of the commits in the heatmap below are merged PRs into the Nym monorepo.

    Nym provides strong network-level privacy against sophisticated end-to-end attackers, and anonymous transactions using blinded, re-randomizable, decentralized credentials.
