Python and Azure inspire me to explore various skill sets and diverse technologies. My passion is the use of batch and real time processes to generate fresh data products with high business value. I achieve this with data/ML engineering, security/privacy engineering and software architecture. I am happy to share knowledge with and learn from anyone with shared interests.
At NS we are running AI systems in production that improve the customer travel experience through the NS App. Our lambda architecture keeps our batch predictions fresh with stream processing of changes to the physical train layouts. Streams are also used to anonymize customer data (check in/check out) and simplify ETL processes.
Together with talented people I set up an AI team at the Volksbank. I applied myself fully in this data driven project as a senior engineer and solution architect. I implemented a big data architecture I designed on the basis of the lambda architecture. In early 2020 the 'mijn budget' product processing transactions of 1 million customers went live and is now available in the SNS app.
Trainer and inspirator at the Rabobank. I am training the new generation of Python data and risk modelers at the Rabobank.
Main engineer of a deep learning workshop with reinforcement learning based on Tensorflow. Positive feedback from visitors at TeqNation 2018
I jumped into an ongoing project close to release, which had a bad security posture. I took the initiative and practiced ethical hacker skills in combination with application monitoring to pinpoint security issues and solved them with secure development practices.
Enterprise Django applications within a new architecture of secure services including a recommender service. I developed a service oriented architecture with my team. I designed and implemented security critical REST APIs with various authentication and authorization mechanisms. I created a personal wine recommender engine together with a wine tasting expert.
Development of security and privacy applications. I worked on a network meta-data analysis engine and a secure email application. I interacted with ethical hackers through code audits and conference visits.
