Work Experience

ABN AMRO - Data Engineer Full-time Apr 2020 – Present 1 yr 2 mos Amsterdam, Netherlands
  • Developed a data platform (based on Quantexa) that creates interactive and expandable networks of customers, companies, products and transactions to provide better context for financial fraud investigations.
  • Used entity resolution to extract entities from data and graph analytics methods to build a model that helps us to create a more complete and detailed overview of each client, and provides better insights to do risk scoring.
  • Responsibilities involved a mix of data engineering, development, operations and data science, as well as coordinating the implementation of controls related to continuous integration, delivery, testing, monitoring and operations and security, to ensure that the application and the team is in control and complies with all the standards of the bank.

Projects

Open Source Project: Foronoi Github Documentation Pypi
Foronoi is a Python package that I developed that implements a sweep line algorithm for Voronoi diagrams. It scans top down over a set of points and traces out the borders along the way while scanning for the next point. My package includes a visualization API, the ability to clip the diagram inside polygon bounding-boxes and some other extras.
Master Thesis: Automated Machine Learning Github Thesis

My master thesis was on the topic of Automated Machine Learning, which is the field that strives to automate the data scientist's process of finding and optimizing the right machine learning model. We do so by testing machine learning models with different configurations and observing their performance to determine interesting configurations to test next. This can be done in many different ways: genetic programming, bayesian optimization, bracket-wise competition, etc.

I developed a new method closely related to bayesian optimization that uses much less time to decide interesting configurations, and converges faster to the optimum.

Bachelor End Project: TravelMatch
Developed an Android/iOS app that learns what your personal "travel DNA" is, based on the liking and disliking of travel images, and then recommends holiday destinations using affiliate links.
