Freiburg, Baden-Württemberg, Germany
With over 20 years of experience in web applications, I have a strong background in the conception, architecture and implementation of cloud-based solutions using Angular, RXjs, Node.js or PHP together with established OpenSource framweworks. I have worked for agencies and companies as a senior and lead developer, delivering web applications for various domains and industries. I am passionate about creating innovative and sustainable digital products that have a positive impact on the environment and society. I am open-source fan & contributor in various projects.
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
As a senior software developer I have 20+ years of experience as a freelancer and employee and have worked for start-ups, SMBs & agencies with a strong focus on web applications (full stack). I am particularly interested in contributing to projects and companies that are dedicated to sustainability, climate change mitigation and transformative solutions for a eco-friendly future.
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.
