Experience

2021 - now
Software Developer
OTARIS Interactive Services GmbH
At OTARIS, I primarily work in Software Development. The focus of my work was initially in IoT security, consulting for customers, but I have since pivoted to a software development role. A major project I developed in this capacity was a measurement system to assess the quality of service of a 5G network by geolocation. Greenfielded in Go for a custom Linux-based platform, this is the most prominent project I have worked on and still maintain here.
2019 - 2021
Teaching Assistant
Universität Bremen
I supported the course Technische Informatik 2 for multiple semesters under Dr. Olaf Bergmann, a course which deals with operating system concepts and concurrency. I also supported the course Technische Grundlagen der Informatik.
2014 - 2015
IJFD (Voluntary Social Year)
Centro Educativo Stella Sierra
I worked as a volunteer assistant teacher in a secondary school.

QoS-Probe
This project I helped start for our company from the ground up in order to serve a customer. From gathering requirements through developing a prototype, drafting a final architecture and ultimately realizing it before delivering the project, I was integral to its success. The project realizes a measument system for mobile networking quality in relation to geolocation, so it gathers various quality indicators and correlates them to GPS data (which it also has to process).
Go, 5G, mobile networking, Linux, QoS, ELK, React, NMEA
QoS Android App
In order to make the QoS Probe more flexible in its application and to better support 3D measurements (drone mounted) I integrated the QoS Probe measurement code into an Android App. This involved a fair bit of cross-language interoperability wrangling and I am quite happy with the results.
