A simplistic library for Aspect Oriented Programming (AOP) in TypeScript

This is a library for defining and using aspect, which can be used to encapsulate so-called cross-cutting concerns, such as logging. This in turn enables developers to write code that is more maintainable and reusable.

One goal of this open source project is to provide an API for aspect-oriented programming in TypeScript that is as easy to use as well as flexible - without any additional dependencies. ts-aspect can also be used together with frameworks such as NestJS (see here).

A simplistic library to listen for and produce messages to Amazons Simple Queuing Service (SQS)

go-sqs is based on the AWS SDK for Go and provides an easy-to-use listener and producer for SQS messages. An error-based routine is used to receive messages. It enables the definition of custom logic for processing SQS messages, takes care of any occuring panics and deletes the message from the queue on successfully processing it.

I am currently working on a sidecar implementation which provides the functionality of go-sqs as a REST-API. This enables the usage of go-sqs within applications written in different programming languages or frameworks.

I am currently working at Red Hat as a Software Engineer.

Working at Netlight as an hands-on IT consultant allowed me to get to know a wide variety of industries and companies as well as their culture, structure and the technologies used there. Netlight also offered me the opportunity to try out new roles and to develop myself personally in different areas. This way I was able to accumulate wide-ranging knowledge - from the implementation of JavaFX Fat Clients in a small team using Kanban to developing complex event-driven microservices using GoLang and NestJS as well as micro frontends using React with up to 6 Scrum teams, which were organized according to Nexus framework.

After successfully completing my bachelor’s degree, I wanted to further specialize in software engineering. During my studies I gained deeper knowledge about distributed systems as well as initial experience working on open source projects (see PR320 at jenkinsci/acceptance-test-harness). I also discovered my passion for machine learning and deep learning during my master’s degree. In addition to my studies, I had a job as working student at an IT consulting company where I gained experience in agile project work and JavaEE.

Evaluation of Machine Learning methods regarding the applicability in a test automation framework for in-vehicle infotainment systems

For my master’s thesis, I examined various Object Detection methods regarding their applicability in a test automation framework. First, I developed a program to automate the generation of labeled training data, which later saved a lot of time as this step is very time-consuming. Then I implemented the Template Matching as a classic object detection method with* Python* and scikit, a machine learning model based on HOG features using scikit-learn and the Deep Learning model Faster R-CNN with TensorFlow. To evaluate the different approches, I used the so-called Intersection over Union as a metric. In a final proof of concept, I extended the existing framework by the newly developed object detection functionality and implemented a pipeline for the automated training of further models.

At the end of my apprenticeship as an IT specialist, I made the decision to study computer science. Here I learned a lot about topics such as data structures, algorithm design and algorithm analysis as well as methodologies for problem solving and project management.

For a project at university, two other students and I implemented a web-based review system using the Python-framework* Flask* ​​and MySQL. This system was then used to support a class at the university. In addition to my studies, I had a job as a working student at a manufacturer of cash register and cashless accounting systems where I implemented new features with Object Pascal.

A study for redesigning and improving the usability of the OpenDXM GlobalX User Interface

In my bachelor thesis I examined the Managed File Transfer application OpenDXM GlobalX in regards to its usability. I first carried out an eye tracking study to get data about usability problems of the application. I used the gained knowledge as well as the Android Design Principles when creating a new design proposal. For this I implemented an interactive prototype using HTML5,* JavaScript* and CSS.

During my apprenticeship, I worked on an in-house, multilingual Enterprise Resource Planning system in a small team of developers. The ERP system used MSSQL for persistence and was written in the programming language Object Pascal in a procedural style, using* Delphi* as IDE. I also learned C# as my first object-oriented language in vocational school and C++ in my free time. Using VBA to automate the various evaluations as well as generate respective visualizations for different departments were also part of my tasks.

In my thesis, I added a calculation module to the in-house ERP system. This included requirements analysis, planning, implementation and testing. The new module made it possible to recalculate the valuation price of various products.
