As the Lead Data Engineer at Aimwel, my role involves harnessing data to drive performance marketing strategies for job boards. My journey began as a Data Engineer, where I honed my skills in data handling and analysis. Now, as the Lead, I oversee the development and implementation of sophisticated data systems. My work is integral to ensuring that Aimwel's data-driven solutions remain cutting-edge and effective in a rapidly evolving digital marketing landscape.

As a consultant, I mostly worked with Power BI and SQL databases. For a client, I designed and proposed a modern infrastructure within the cloud for data storage and visualization. For another client I worked with a colleague on the design of a data integration between their backend and Tagetik and Anaplan. Internally, I worked on dashboards to visualize the finances of Rockfeather and improved their database structure.

Besides my work as a consultant, I followed the Rockfeather traineeship for personal development.

As a freelancer, I was responsible for visualizing data based on the total patient population. Before I could start visualizing, I designed the infrastructure of the database from scratch and built all queries for ETL (extract, transform and load) in SQL. To visualize the data, I linked Power BI to the database and build dashboards. All decisions on what data to use and how it should be visualized were done together with doctors within the department of Nephrology.

Halfway through the two years I started transferring my knowledge and all information regarding the project to my successor, who was among other things hired to maintain the project after my leave. He was a Postdoctoral researcher in the medical field with no prior programming knowledge. Therefore, I taught him the basics of SQL and Power BI.

The job has been done within the agreed time. The project has been extended two times to create more visualizations and link more data sources to the database.

Peeeks is a start-up that generates extra revenue for clients by automatically and intelligently controlling flexible electrical assets, dependent on availability in price of electricity on the grid. As a software engineer I helped design and built the cloud infrastructure of storing renewable energy in boilers. The project involved telegram bots for installing boiler devices, IoT for communicating with boilers and data streams for storing the vast amount of data collected from boilers, all within the AWS cloud.
