Open Source Contributor · Protocol Labs Dev Guild

Core contributor to py-libp2p (transport layer, connection management, bootstrap & discovery, test infrastructure), C#/.NET contributor to dotnet-libp2p (Circuit Relay v2, Yamux dynamic window, peer-scored GossipSub), modernisation lead on py-ipld-dag, upstream fixer on py-multiaddr. Reviewed and co-authored 14 additional PRs across the ecosystem. Architect of the six-phase WebRTC transport plan for py-libp2p (Phase 0 shipped).

Flagship cohort. Shipped comprehensive IPv6 support across py-libp2p transport + WebSocket (#1132), DNS bootstrap discovery (#1198), semaphore-backed DHT + Swarm concurrency (#1274, #1289). Ported Circuit Relay v2, Yamux dynamic window, peer scoring to dotnet-libp2p (#180, #178, #172, #177). Authored a six-phase WebRTC transport plan (issue #546) — Phase 0 shipped.

Structural plumbing of the Swarm connection lifecycle. Refactored Swarm close-method into a single canonical close sequence (#1029); landed the advance connection-management state machine (#1092). Decoupled peer-ID from address introspection via Host.get_transport_addrs() (#1080) — unblocked the IPv6 work in Cohort 6.

First contact with py-libp2p — transport-layer utilities, cross-platform stability, WebSocket. Enhanced the WebSocket transport with configurable subprotocols, payload limits, ping/pong keepalive (#964). Centralised cross-platform path handling via pathlib (#886, #1239, #1251) — unblocked Windows CI.
