  • Project Manager & Contributor Delta Chat Desktop Application at merlinux GmbH
    Aug 2024 - Present · 1 yr 11 mos

    https://delta.chat is a OpenSource Instant Messenger available as Android and iOS app and as desktop application. It is based on a Rust core which provides secure end-to-end encrypted communication. Since the underlying protocol is based on IMAP/SMTP, the required servers can be run easily by "anyone", since they are basically lightweight mail servers. I contributed to the project already years ago and am now involved again as a contractor and team manager responsible for the Delta Chat desktop application. The general objective of the project is to provide a messenger with a focus on privacy, security and independance from US-based tech giants. #privacy #decentralization #openSource #peer-to-peer

    Wir entwickeln eine digitale Plattform für die Zertifizierung von Aufforstungs-Projekten in Deutschland nach dem Wald Klimastandard. Bei der Zertifizierung wird der durch die Aufforstung entstehende CO2 Speicher ermittelt und geprüft ob alle Kriterien des Wald Klimastandards erfüllt sind. Alle wichtigen Eckpunkte der Projekte werden transparent auf einer Webplattform dargestellt und regelmäßig überprüft. Die CO2 Zertifikate können verkauft werden und finanzieren damit die Aufforstung.
