At Qabam, we believe innovation can be fast and effective. No endless meetings or slow processes — we experiment, validate, and adjust immediately. With a small, specialized team, we deliver tangible results without turning everything upside down.

Being responsible for the secure and PCI-compliant implementation and 24/7 operations of our Africa focused payment orchestrator I focused on fast iterations, data driven decisions and knowledge sharing. Within six months we built a stable valuable product with a measured double-digit conversion improvement.I started implementing from scratch on my own as it proved difficult to immediately find the right people. Time is of essence at a startup, so being able to quickly move mountains turned to be invaluable. Within 3 months we were live with the following setup:Infra- Three Terragrunt managed Google Cloud environments (dev/stg/prd) with encrypted state. Cloud Run, Cloud SQL, Cloud Armor, Shared VPC, Load Balancer, BigQuery, KMS, Secret Manager, Compute Engine, Cloud Storage, Pub/Sub, Cloud Monitoring + AlertingBackend- Multiple async & typed, integration tested and documented Python API's using FastAPI, Alembic and PytestFrontend- Secure server side rendered payment pages using Nuxt.js (Vue3), Tailwind CSS and Typescript- Merchant portal using Vue3, Typedscript and Tailwind CSSAnalytics- BigQuery, dbt, Looker Studio, Snowplow on Cloud RunDevOpsGithub Actions + OIDC, Devenv.sh / Nix, Docker, Sentry, SlackOver the course of several months I hired an Analytics Engineer and a Backend Engineer to further build out the company and the product. I truly enjoyed sharing my knowledge and experience by providing extensive code reviews and pair programming sessions, resulting in an aligned and consistent way of working.

As a software engineer and consultant at Xebia I'm specifically interested in functional programming preferably using Scala, finding a fitting solution to an existing problem, and handling and making use of large amounts of data.

Graduation ProjectThe domains of healthcare and Information and Communication Technology (ICT) are very different. In healthcare, human beings are in the center of attention. When considering the domain of ICT, computing and connectivity first come to mind. It is suggested that the first step in bridging the gap between the two domains is to focus on the essence of care processes, independent of their realization and implementation. In other words, independent of any technology that is required to make them operational. As part of this essence, communication and (social) commitment turn out to be indispensable. Both subjects are currently insufficiently paid attention to, as this thesis will reveal. In this report, three applications of the Dutch national Electronic Health Record are analyzed and redesigned from an Enterprise Ontology viewpoint. Enterprise Ontology is an emerging field in the information sciences and engineering disciplines that has its roots in communication philosophy. It provides the required theory and a matching methodology to pursue this goal of bridging the healthcare and ICT domains. Instead of adjusting ‘the business’ to each individual application of the Electronic Health Record, a single shared perspective on care processes is provided. It demonstrates that the activities of the various care professionals at their core generally do not differ. Furthermore, it secures the consistency and coherence of the application designs, while presenting all important and sensible aspects in a concise way. This approach is thought to be the only correct starting point to determine, design and implement supporting information systems for the healthcare sector or any enterprise in general.

Intern at the CIO office on Role Based Access Management. This resulted in the paper "Role Based Access Management, Ready for take-off?"

I maintained the University’s homepage news and agenda sec- tion. I also designed and created in Adobe InDesign a month- ly paper about future academic events (Wetenschapsagenda);
