Data Processing

Data pipelines extract, load and transform data from source systems to a data warehouse. I use modern processing solutions, which are scalable and can handle large amounts of data to orchestrate and build reliable data pipelines.


To create insightful analytics, a well-structured and maintained data warehouse is essential. I design and implement data models using different data modeling techniques to build up a clean structure for your data warehouse. Depending on your needs, these data warehouses can be on-premise or cloud-based.


Analytics Engineers build a bridge between data engineering and data analytics. I collaborate closely with data analysts to understand business requirements and transform those requirements into technical solutions.

Data Visualization

There are hundreds of different ways to visualize your data. Generate a report, create a dashboard or implement to web application? I support you with the visualization method that suits your needs and implement it using up-to-date visualization technologies.

About me

Moin, I’m Sven. I am a freelance Analytics Engineer with around five years of experience in various data projects.
Originally I started my career in aeronautical engineering, but after I finished my master’s degree, I began to follow my passion which was more software than hardware driven. I spent a couple of years accomplishing and leading different projects in data analytics for the aircraft industry before I started my career as a freelancer in analytics engineering.
Today I support companies building powerful data platforms by applying software engineering best practices with modern technological solutions.
When I am not at work, you can find me enjoying a lot of different sports. I play badminton, go for bike rides, go standup paddling on the Alster, and many more.
