Developer of Nheko.
Representing the ecosystem on the governing board.
Employed by Famedly to work on Matrix in the healthcare sector and beyond.
Noisy and too involved in too many things.
I am still very proud of fixing the bug, where Synapse wouldn't let you rejoin rooms you have been unbanned from, unless another user from your server was in the room.
I got rid of reply fallbacks.

The Matrix.org Foundation is the key to Matrix' independence from any commercial vendor. It exists to protect the neutrality of the Matrix protocol, promote Matrix as an open standard, give a voice to the members of the ecosystem and ensure trust and safety within the open network. This keynote will give an overview of the latest about the Foundation and will include a presentation from the Governing Board on the activities led by the various Committees and Working Groups.
When you operate communication infrastructure for one of Europe's largest defense organizations, "good enough" is never good enough.
At BWI, we do not just run Matrix. We trust in the idea behind it: that secure, open communication should be a public good.
This talk traces that journey. It begins with our decision to adopt Matrix as the sovereign communication backbone for the German armed forces, and the architectural ambition that drives our work: a communication stack where the functional core is formally verifiable, and memory safety is a given everywhere else. An engineering target we are actively working toward.
As a first step toward that goal, working with Element, we brought a Rust-based cryptographic SDK into existence, the Matrix Rust SDK, a unified crypto platform shared across all our client applications, born from our security requirements and built to last. Rust was not an aesthetic choice. It was a deliberate decision rooted in memory safety, auditability, and the practical requirements of formal verification tooling.
Our work did not stop with the SDK. The same questions that shaped our cryptographic foundation led us to ask harder ones about the backend: what would a homeserver look like if security and formal verifiability were first-class requirements from day one, not afterthoughts? We have been exploring that question, and in this talk we want to share what we have learned so far, the decisions we faced, and where those explorations have taken us.
Join our journey.
