About Me
Welcome to my profile!
My name is Paul Köpke, I am 29 years old and have been working in professional software development for over 5 years.
My focus is on modern frontend development, complemented by several years of experience in backend development.
So far, I have gained experience working in a digital agency on various client projects, in enterprise product development at lexware, and nearly 2 years as a freelance software developer.
I place great value on clean, understandable code, clear structures, and maintainable, tested, and high-performance solutions.
Through my studies in business administration and online marketing, I bring not only technical expertise but also a business and user perspective.
In my free time, I also enjoy working in the field of game development with Unity/C# and exploring gamification.

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 developed.Nest.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 more than 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 motivated.Print 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.
