I am working in a Mobility Analytics and Consulting Team, where I provision the required virtual hardware (via Openstack / SaltStack / Terraform) for our high performance computing pipelines, establish and maintain a modern CI/CD based software development lifecycle (mostly centred around GitLab & Nexus) and also work as a software developer (mostly Java) on improving our custom tool chain.

1) TA: lecture organisation, managing tutors, teaching lectures/seminars/tutorials, student supervision. 2) academic research, writing scientific articles, conference presentations 3) System Administration: maintenance of Debian & CentOS server landscape, partially Xen virtualised. Administration of public /24 net and associated domain (DNS, DHCP). Maintenance of lab website (basic LAMP stack). Other services: git, ssh access, mail (exim), central sign-on (LDAP), file sharing (via SAMBA et al.).

I worked with the infrastructure branch on a new piece of code versioning software and was responsible for an algorithm to easily access the author and time of creation associated with a given line of source code (e.g. a blame/praise feature). I integrated the algorithm into an existing client-server-architecture and made it accessible from other internal systems. The code was developed in C++ on a Ubuntu Linux System using Perforce versioning for development purposes.

Development and evaluation of techniques for mechanising correspondence proofs between various representations of syntactic systems with local variable binding (e.g. lambda calculi) in proof assistants like Coq, Abella and Beluga.

Bachelor Thesis: "Reconsidering Lucid -- a modern approach": Scala implementation of a compiler and actor-based, concurrent demand-driven run-time system for the dataflow language Lucid, evaluated against the pLucid reference implementation.
