About Me
Welcome to my profile!
I'm Paul – a Fullstack Freelancer with a great passion for modern software development and powerful B2B products. For over 5 years, I've been helping tech teams drive their projects forward successfully.
Through my roles in enterprise product development (Lexware), digital agencies (Team Neusta), and now two years as a freelancer, I know both worlds: complex enterprise structures and dynamic agency projects. I integrate seamlessly into your existing processes and teams, delivering reliable, production-ready code right from the beginning.
What makes me stand out as a developer? Thanks to my background in Business Administration and Online Marketing, I always look beyond the code itself. I keep the business perspective in mind and focus on the user experience – ensuring the final solution delivers value for both users and the business.
Are you looking for flexible, reliable reinforcement for your next sprint or to cover a team bottleneck? Let's connect for a first call.
I look forward to working on your project!

Haufe-Lexware GmbH & Co. KG
At Haufe-Lexware, I worked within the payroll team on several Java/Spring Boot microservices as well as the Next.js frontend.

This project featured a C# backend with a custom-developed framework, where both the server logic and the templates for an authority's online forms were implemented.Nest.js ETL Data Pipeline
team neusta / neusta GmbH
In this project, large volumes of data were fetched from various sources, transformed, and subsequently written into a database for a web service. The web service exposed the data via a REST API. The project's challenges lay in the deep technical nature of the data and the complexity of the transformation process.Microservice Web Application for the Construction Industry
team neusta / neusta GmbH
The goal of this nearly 2-year project was to develop a modern system based on a complex legacy Spring web application. A microservice architecture was chosen to improve load balancing and module interchangeability. The backend comprised over 20 services and was orchestrated using Docker Compose. The main complexity lay in a sophisticated, custom-built processing engine for exotic file formats and an adaptive matching logic. The frontend was structured as a micro-frontend architecture within an Nx workspace. The individual micro-frontends were implemented as Angular applications and utilized NgRx for state management.Gamified Donation Platform for a Recycling Initiative
