Arnas

As a Chief Technology Officer at Meedio, I lead the development processes and the strategic adoption of new technologies, with a particular focus on the Matrix protocol and end-to-end encrypted (E2EE) video communication solutions. I have been with Meedio for over six years, initially joining as a Lead Backend Developer, then advancing to Head of Development, and eventually becoming CTO. In the leadership role, I have been instrumental in building new teams, driving technological direction, and delivering tailored, high-security communication solutions for strategic clients. I also oversee compliance and certification processes, including the implementation of GDPR.

Before joining Meedio, I had worked in the fintech sector on projects aimed at centralizing multi-bank access for users, enabling consolidated asset management across financial institutions. In recent years, my primary focus has been on secure, encrypted video communication in regulated sectors, particularly IT healthcare, where data security and governance play a critical role.

Carla Griggio

Carla is a tenure-track assistant professor at the Department of Computer Science at Aalborg University in Copenhagen, where she researches and teaches Human-Computer Interaction. Her main research studies how communication technologies, especially messaging apps, affect interpersonal relationships, and how the way people use one platform interconnects with the way they use others. She conducts empirical studies to understand how people adapt software to fit their communication needs and builds prototypes that explore ways of providing them with richer control over their expression and online privacy. She currently manages a 4-year long research project about managing privacy and social boundaries in interoperable messaging platforms.

Half-Shot

Half-Shot (or Will) was the lead maintainer of integrations on matrix.org for many years, and now is retired to simply doing all the other things instead. Famous for causing things such as the libera.chat IRC bridge, replacing everything with the Hookshot bridge, and the most cursed implementations of bridge encryption.

When he's not doing Matrix things, he is making terrible indie games, running somewhere, or possibly making a fuss of a dog!

Jan Kohnert

Hi, I’m Jan. I’m driven by the belief that technology improves lives. My focus lies in innovative software solutions, especially in Health Care, where enhancing patient outcomes and quality of care is at the heart of what we do.

As Product Owner for the TI Messenger at gematik, I’m shaping secure healthcare communication.

Great software connects people, simplifies processes, and enhances patient outcomes and quality of care—this inspires me every day.

Jan Krammer (Janonym)

Hi! I am a nerdy ambivert who recently moved to Vienna and I'm trying to not trip over my own fingers while learning jazz and classical piano.

I started seriously tinkering with Linux and FOSS in high-school and that addiction only got worse over time. Fast forward 15 years and that gusto got me into working with universities and institutions running their own FOSS stacks: from Jitsi to Matrix, Linux to Kubernetes and more.

I work closely with Fairkom and their projects, especially in the Linux and Kubernetes infrastructure and of course a lot of Matrix.

Researcher in medical informatics at FAU Erlangen and IT project manager at University Hospital Erlangen, where I lead the Matrix-based TI-Messenger rollout. For 15+ years I’ve been active in civil protection, focusing on information & communications, outage resilience, and critical infrastructure. I studied Information Management in Healthcare (Ulm) and Medical Process Management (Erlangen). My PhD, IM-CURE (Instant Messaging for Crisis & Urgent Response in Emergencies), explores how structured, asynchronous messaging can keep clinical care safe during IT failures and crisis scenarios.

networkException

Hi! I'm networkException (she/they) and have been around as such for quite a few years in the Matrix Community and everywhere else online.

By day, I'm an IT architect at FITKO, a German government agency facilitating cooperation on IT topics between the federal government, member states and various other federal actors. Here I'm looking at Matrix as a tooling to achieve various goals like sovereignty, sustainability and security- and privacy by design within the ever evolving, ever more complicated IT landscape surrounding the German government.

At night I'm more of a developer, system administrator as well as train-, privacy- and security nerd and open source linux distribution and browser maintainer. I'm active in various communities, including maintaining the ungoogled-chromium browser patchset, improving open data for public transit or simply hosting (currently) 4 Synapses (and counting!) for fun and no profit

Patrice Zoe Brend'amour

As a Vienna-based software professional with an advanced background in DevOps engineering, system administration, and technical content creation, I combine hands-on expertise with a passion for open technologies. My career spans software development, infrastructure automation, and container orchestration, emphasizing the adoption of scalable, privacy-conscious platforms in complex sectors.

With a strong interest in aviation and regulatory standards, I bring a detail-oriented and research-driven approach to every project, including the evolution of secure communication systems. In my daily work, I practice self-hosting solutions and advocate for open protocols that empower organizations to control their data and foster interoperability.

At this year’s Matrix Conference, I will address "Matrix as a Bridge – Enabling Cross-Border Healthcare Communication Through Open Standards," exploring how Matrix can transform healthcare data exchange, enhance patient privacy, and support seamless collaboration across borders. Drawing on my technical experience and insights into regulated industries, I will demonstrate how open standards lower barriers and create new opportunities for healthcare innovation.
