About Me
I’m glad you found your way to my profile!
I’m Paul, 28 years old, and I’ve been working in professional software development for over five years.

Work Experience
Event Dashboard
HypeIT GmbH
Development of a Next.js front-end application to structure and collaboratively process tasks arising during event planning.Custom ERP System
In 2024, I was given the opportunity to work on a major IT restructuring project as a freelancer. A legacy system was replaced and a new, completely self-developed ERP system was introduced. I supported the project with C# backend services and a React frontend.Fullstack Accounting Webapp
Haufe-Lexware GmbH & Co. KG
At Haufe-Lexware, I was able to work on several Java/Spring Boot microservices and on the Next.js frontend in the payroll accounting team. What I found particularly exciting about this project was the technical proximity to my former business studies and the live deployment of an application with more than 200,000 users.Online forms for a public authority
team neusta / neusta GmbH
This project is characterized by a C# backend with a custom developed framework, in which the server logic as well as the templates for online forms of an authority were developedNest.js ETL Data Pipeline
team neusta / neusta GmbH
This project involved retrieving a large amount of data from different data sources, transforming it and then writing it into a database for a web service. The web service made the data available via a REST interface. The challenges of the project were the high technical depth of the data and the complexity of the transformation process.Microservice Webapp - Construction Industry
team neusta / neusta GmbH
The aim of this project was to develop a modern system based on a complex Spring legacy web application. In order to better distribute the load and make modules interchangeable, a microservice architecture was chosen. The backend contained morethan 20 services and was orchestrated via Docker Compose. The greatest complexity of the system lay in an elaborate customized parsing of exotic file formats and an adaptive matching logic. I also took on many tasks in the frontend and gained a lot of experience. The frontend was structured as a micro-frontend architecture and was developed in an Nx-workspace. The individual micro-frontends were Angular applications and used NgRx as state management.Gamified Donation Platform for Recyclable Collection Initiative
team neusta / neusta GmbH
In this project, an Angular frontend and a Spring Boot backend were developed for a voluntary recycling initiative. Particularly exciting were the many gamification elements that were intended to encourage users to become more motivatedPrint Module for a custom ERP System
PD Software GmbH
As a working student, I was assigned to independently develop a printing module for the company’s self-developed ERP system. The module was built in Java and communicated with the ERP system via sockets.Raspberry Pi BDE Client
PD Software GmbH
My first independent project as a working student involved the autonomous development of an MQTT client, which was deployed on Raspberry Pis for the purpose of operational data collection. The client simplified and standardized the access to and reading of the Raspberry Pi GPIO pins via MQTT over a network.Ownership & Service Terms
To clarify a few questions in advance, I have defined the following fair ownership and service terms for my services:
All code and deliverables created during our collaboration are fully owned by you, the client. After the project or development phase, you have complete rights to use, modify, and deploy the software as you wish. I provide my work strictly as a service — meaning you pay for the development effort and expertise I bring to your project.
Regarding hosting, it remains the client’s responsibility and liability. I can support you with hosting setup advice or management as an hourly service, but the hosting accounts and infrastructure are owned and controlled by you. This way, you retain full control over your product and infrastructure, while benefiting from professional development services.
