Adam in het kort

Throughout my career, I have grown to become a well rounded "data guy" able to work on all stages on all projects from data modelling to data engineering, to reporting and data science. At Tripaneer I contribute to multiple high impact projects across all departments. Such projects include working on the very first recommender engine, data driven marketing attribution and defining an approach for supply management. I also trained our business users on our BI tool (Looker) allowing me to focus on more complex and challenging tasks.

Amsterdam, The Netherlands

augustus 2020 - juli 2021 (11 maanden)

At Randstad, I worked on a project to create a Recommender Engine for recruiters to find the suitable candidate. In this project, because of the size of the project, I used PySpark extensively for data cleaning, feature engineering and machine learning model training. I also used NLP techniques such as TF-IDF and Transformers based embeddings to extract and mathematically encode information that is in the candidates’ CVs.
