Delitzsch, Saxony, Germany
Over the last 10 years I was involved in a variety of projects from building local community mesh networks to developing firmware and management software running on millions of home routers on to developing customized solutions for service provider networks based on Network Programmability. I'm a supporter of open-source software both by helping individuals and companies to efficiently use and contribute to various projects and by being a contributor and maintainer myself. Since 2008 I'm one of the core developers of the OpenWrt Linux distribution for embedded devices. My development focus: Network Protocols and Routing, especially IPv6 & related Linux and POSIX system and networking, services, kernel interfaces & integration C, C++, Python, Java NETCONF/Yang, Docker, Segment Routing
* Developing custom SP solutions based on NETCONF/Yang, Telemetry, Segment Routing and other Programmability APIs and SDN Features * Developing and deploying customized cloud-native applications using Docker on servers and networking equipment
Developing internet drafts & implementations for the IETF Homenet working group focussing on next-generation self-configuring IPv6-enabled home networks. OpenWrt consulting and integration.
