I'm a software engineer and IT security researcher interested in email security, network protocols, and applied cryptography. I believe in public software, open access to knowledge, and a world with net-zero greenhouse gas emissions.
Rustacean. He/Him.
I recently started a journey as a freelancing software engineer to work on projects and with clients that share my passion for open-source software.
My core strengths encompass email protocols, applied cryptography, public-key infrastructures, and diligent software design in Rust. Generally, I enjoy writing parsers for complex protocols and designing usable, misuse-resistant APIs. Still, I am inquisitive and would love to work with geo-information and embedded systems to enter the renewable energy sector.
I co-authored several research papers on end-to-end encrypted email (IMF, MIME, S/MIME, OpenPGP, …), transport encryption (TLS, X.509, …), and web security (ALPN, SOP, …) that uncovered numerous security issues, leading to protocol revisions in Internet standards such as S/MIME, OpenPGP, and the IMAP protocol.
Beyond my technical expertise, I can translate complex technical topics into accessible, engaging content for a broader audience to promote projects effectively.
I am particularly drawn to projects promoting open-source software, secure communication, and clients in the renewable energy sector. These are my dream clients, as leveraging technology in these spaces is crucial for our future.
I'm a transparent person, and, as far as I can tell, people generally enjoy working with me :-)
