2010 ? 2014

Bachelor of Science

Universität Freiburg


Focus:

Unsatisfied with my role, after completing an apprenticeship as a programmer, I chose to study computer science.


2014 ? 2017

Master of Science

FU Berlin


Focus:

After my Bachelor?s degree, I decided to go to Berlin to focus on operating systems, security and cryptography. With two full professorships dedicated to these subjects, FU Berlin was the best location for these subjects.

C, C++, Java, Scala, Spring, JBoss/Wildfly, CI/CD, Jenkins, CircleCI, GitLab, GitHub, git, Android, iOS, Bash, Linux, Gentoo, Debian, RedHat, Gradle, Python, Django, Terraform, Infrastructure-As-Code, AWS, Amazon Web Services, Amazon Well-Architected, Ansible, Docker, Kubernetes, OpenShift, Istio, Jira, Confluence, Apache Storm, Apache Kafka, Stream Processing, ETL, Elastic Search, Service-Oriented Architecture, Networking, Security, VSphere, VMware


Profile

  • My professional career began as a software developer at a company in Munich/Germany where I completed an apprenticeship and subsequently worked as a developer before I decided to study computer science, completing a BSc at Albert-Ludwigs-Universität Freiburg and an MSc at Freie Universität Berlin.
  • While studying, I was active as a freelance embedded developer, a system- and network engineer. Part of these works was the design and implementation of a network boot system based on Linux that powered the office and development environments of a company in Freiburg.
  • After completing my Bachelor?s degree, I decided to attend courses at FU Berlin where with Marian Margraf, who designed the security around the German ID card and Volker Roth, two full professorships were dedicated to IT-Security and Cryptography. The program consisted of challenging mathematical problems from the algebraic domain which form the foundation of asymmetric cryptography. Problems concerned the construction of security schemes such as message authentication codes, encryption, hashing as well as attacks on those.
  • As cryptography can only protect data when provided with a secure operating system, in practical projects, I wrote an advanced firewall based on Linux Kernel modules for deep packet analysis as well as a small microkernel operating system for an ARM development board, researching a minimal kernel feature set required to provide security and isolation for processes.
  • After completing my Master?s, I started working as a DevOps Engineer, expanding my domain knowledge to cloud projects.
  • I consider myself an agile individual as indicated by the first line of the Agile Manifesto ?Individuals and interactions over processes and tools?. I enjoy building with other skilled and self-responsible individuals who are ready, able and willing to stand their ground in rough times and do not need universal agreement to know what is right.
