Curriculum Vitae

Software Engineer

Extensive work on an in-house developed workflow orchestration engine written in Python, simply named 'Workflow Orchestrator'.

The Workflow Orchestrator is an open source project providing tooling for network automation and orchestration (see https://workfloworchestrator.org and https://github.com/workfloworchestrator).

The project is used by network engineers from companies in different parts of the world (SURF, ESNet, GÉANT and more).

A important part of my contribution was implementing full-text search capabilities for all provisioned resources by a client. This was built on top of PostgreSQL with a custom easy-to-use query language.

Data/Software Engineer

Part of a central DataHub Team responsible for all data flows in/out of ANWB.

Active both as platform engineer, extending the custom modular CDK framework for creating new pipelines, and as an engineer analysing use-cases and on-boarding business-teams to our platform.

Data/Software Engineer

Data engineer for a customer-focused DataOps team. The team built a generic framework in a monorepo for ETL pipelines using S3, RedShift, Stepfunctions, Lambda and AWS Batch.

As the number of pipelines grew rapidly, the deployment time become too long. I built a new deployment pipeline using CDK pipelines which leverages CodePipeline for deploying stacks in parallel.

Data Engineer

Data engineer for a Data Analytics Platform. Part of a centralized data team that ingests and distributes data for all data scientists and other departments.

We started building a reusable dataflow infrastructure for our ETL jobs that leverage AWS Glue jobs and Lambdas to move data around the datalake.

Data Engineer/Software Consultant

Involved in two large projects.

- Building a new Client Portal with infrastructure in AWS using an almost exclusively serverless architecture. Also involved migration of a legacy data pipeline to a scalable system based on APIs. Infra tools: Terraform, GitLab CI.

- Part of a new foundational Innovation Platform that built new infrastructure and applications for asset management teams. Everything was built with AWS native services. Infra tools: CloudFormation, CodeCommit, CodeBuild, CodePipeline.

Technical Lead/Architect

Full stack development. System architecture and data engineer.

Besides programming, also responsible for the scalability and correctness of the event-sourcing architecture.

System was reaching the limit with 100 registered schools. We grew to 200+ schools and achieved a 120% increase in sold licences.

We were able to keep the infrastructure costs remained constant. The entire stack was Clojure en ClojureScript (and a little bit of Ruby on Rails).

Software consultant

Full stack developer at ING as software consultant. Involved all development tasks from Java Spring to AngularJS and scrum master tasks.

Started an open source project at Xebia: VisualReview (written in Clojure).

Software developer

Employed as developer for Web Applications (primarily backend) in a Service Oriented Architecture.

Big Data Specialization

Completed the 6-part Big Specialization track from the University of California San Diego. (Certificate is shown on my LinkedIn profile)

Data Science Specialization Course

Completed the 9-part Data Science Specialization from the John Hopkins University. The final capstone project consisted of builden a data science product.
