  Arnhem, Gelderland, Netherlands After years of high quality full-stack software development I started taking up freelance projects, specializing in event-driven reactive application development.

Having a portal for client administrators and ultimately customer administrators, as well as an API for the IoT devices using these configurations through the company's applications, we built a system involving multiple parallel and versioned APIs, as well as working together with the company's applications team on devising the way forward for new features. Within a year we've completely rebuilt the portal and the backend, adding new features on top, while also having introduced improvements to the way of working through advice and collaboration with the applications teams. As for hosting this system, Avisi Cloud is utilized: A managed Kubernetes-as-a-Service environment, with automatically provisioned monitoring, user management, etc via GitOps.

The project involved integration with the European eIDAS so as to enable users to sign in through electronic IDs, reviewing the document to be passed interactively during a video call with the notary, being able to sign the document with PDF/A 2 compliant and verified digital signatures. Personally I was mostly involved on the PDF/A 2 compliance and document handling flow parts.

Having used Terraform during the previous position, I worked out several modules which allowed flexible up and down scaling of testing clusters, being configurable in nodes and sizes while integrating with the existing automated build pipelines, and automating the bootstrapping of these clusters and setting up things like configurable role-based access for team members.

Development of the platform involved working with Hashicorp's technologies like Terraform, Consul, Vagrant, Packer and Nomad within Amazon's Web Services. Hosted applications mostly included Atlassian's Jira, Confluence, and Bitbucket, but also services like SonarQube and GitLab.

The system enables users to define custom data views (calculating derived parameters based on custom formulas, filtering the data, etc.) from machine data and production statistics, while being able to choose patterns and/or value-based conditions for actions like notifications, lot holds, tool stops, etc. Besides development activities for the applications themselves, I worked on automated integration & End-to-End testing, user feedback cycles, enabling automated deployments, handling acceptance-testing results, doing production support, within an Agile management process. Technologies used: Programming: Javascript (AngularJS), TypeScript (Angular), Java (8), Scala (2.12), IntelliJ IDEA + Git. Services: Kafka, Zookeeper, Tibco EMS, Cassandra, Oracle Databases, Prometheus, Grafana, ELK stack Libraries: Kafka Streams, Akka, Apache Camel, ActiveMQ, Hibernate, Quill and many more DevOps: BitBucket, Bamboo, Docker, Jenkins, Rundeck Project management: Jira & Confluence Greatly enjoying working on the event processing side of things, I've never stopped taking an interest in this domain since.

This meant I/O testing (and fixing or calibrating) the installation hardware (sensors, actuators, belt-drives, etc.) that were put into place, to then program and fine-tune the system, as it was put into use. Depending on the project's size, engineer availability and deadlines, these projects more often than not had me working at the installation location for 3 to 4 weeks at a time, with 40 to 85 hour work-weeks.

  Arnhem This position had me informing high school students about what they should expect and think about when considering a university study. The goal was to get students to become more aware of their situation, the enormous amount of options available for them and how they can still find their own way in this maze. We did this by hosting afternoons of activities, where we would invite a school's students of ages 15-18 to come to the university or by visiting their schools.
