Oni.nl is a web hosting company I founded in 1999. It now powers a substantial portfolio of client websites. I've engineered the complete hosting stack from the ground up, with focus on building a bespoke control plane rather than relying on off-the-shelf panels. A React/Next.js single-page application powers both the public site and the client control panel, backed by RESTful APIs built with Zend Framework. The platform runs on a Kubernetes architecture provisioned with Terraform and Ansible, delivering a highly available, scalable infrastructure optimized for performance and usability.

This venture has given me end-to-end experience across the web stack - from networking, high availability, and cloud engineering to DNS, caching, mail, and building custom back ends and user-friendly interfaces for managing domains and services.

To streamline and better predict aircraft turnarounds, Aviation Solutions developed "Deep Turnaround", an AI-powered SaaS-product for airports. Cameras at the aircraft stand capture snapshots of each turnaround; a computer-vision model converts these into events - such as baggage-truck arrival or fuel start - allowing precise start/finish detection and duration measurement. The resulting timestamps provide real-time visibility into turnaround progress.

As a full-stack developer, I focused on the user interfaces that make this real-time data actionable for Airport Operations. Deliverables included a Flutter-based native mobile app for iOS/Android, a real-time operations dashboard, a user-management tool, and an innovative annotation tool to support training of the computer-vision model.

Deep Turnaround is deployed and used in day-to-day turnaround operations across multiple airports worldwide.

At Schiphol Airport I worked on “Wilbur,” an in-house application that provides real-time situational awareness across the terminals. This interactive dashboard is used by Airport Operation teams to monitor passenger, flight and baggage flows, helping minimize disruptions and optimize passenger throughput.

As a full-stack developer, I've delivered features such as faceted search powered by ElasticSearch and an interactive map of terminal areas and corridors. I helped scale the stack to a 24/7 mission-critical platform, leading the migration to OpenShift and refactoring the codebase to use Kafka as the backbone for reliably stream-processing hundreds of data events per second.

For this antiques store, I built a multilingual webshop from scratch using React and Laravel Lumen. It’s an isomorphic single-page application with a RESTful backend and a custom CMS to manage content, products, and orders. The site is responsive and tuned for fast performance worldwide. I also focused heavily on SEO, including clean, optimized markup, multilingual sitemaps, and comprehensive structured data.

At Leaseplan I was part of a cross-functional product team developing a new booking tool driven by regular user testing. Within months, this effort became the foundation for "LeasePlan Digital", a new department tasked with building a unified global platform for services across Europe. It was a vibrant environment with a strong engineering culture - regular testing, code reviews, and pair programming across a large shared codebase.

Later, as Tech Lead, I focused on raising code quality, improving team productivity, and strengthening continuous delivery practices. I helped streamline CI/CD workflows, refine standards, and ensure the platform could scale as the organization and feature set grew.

A campaign website to raise awareness of antibiotic resistance among healthcare providers. Using the webcam, each user digitally cultivated a unique, micro-bacteria hand signature, which was rendered into a large, print-ready poster for display in clinics and practices.

I animated the hand signature and built the WebGL pipeline to generate posters at scale - handling real-time capture, GPU-based rendering, and automated output for high-resolution print.

Agency: Superhero Cheesecake

Front-end development for the website of one of the Netherlands’ largest stadiums and concert venues. I delivered a fast, accessible, and fully responsive interface, adding subtle animation details to elevate the design and create a smooth browsing experience for events and ticketing.

Agency: Bureau BlauwGeel

An interactive story exploring the 1666 Great Fire. I engineered a system to georeference and precisely overlay three hand-drawn maps from before and after the fire onto modern London. I built an automated pipeline to process, transform, and tile large historical images, then integrated the results with the Google Maps API to create a seamless, comparative visualization that invites side-by-side exploration through time.

Agency: Logirix

Starting in mid-2014, I joined a cross-functional team to reimagine TNT’s shipping tools (myTNT and the mobile app). After several weeks of iterative development and rigorous user testing, we delivered a well-received prototype that catalyzed the creation of a new department focused on a unified global platform. I contributed to a performant, reliable, and localized booking experience that serves users in 50+ countries and 30+ languages.

In my role as Lead Front-end Chapter, I helped align practices across teams, facilitated code reviews, and streamlined our release process.

At KLM I started out in the Scrum team which was responsible for the homepage - a challenging project to integrate code from multiple feature teams into a single, high-traffic entry point. I then worked on the Travel Inspiration Finder, a visually rich single-page application for aspiring travelers, covering 600+ destinations in 30 languages with filters for budget, temperature, interests, and more.

Built with Backbone.js, this was the first project where I implemented front-end unit and end-to-end testing. These practices were uncommon at the time and noticeably improved code quality and reliability.

Together with visual designer Mathijs Alderliesten, I built an animated, interactive world map for exploring Heineken’s brands and breweries, highlighting their position as “the world’s most international brewer.” The experience was fully responsive and cross-browser, with careful performance tuning to handle rich animations and large datasets while maintaining a smooth, engaging UI.

Agency: Jungle Minds

Commissioned by digital agency Jungle Minds, I developed the front end for the website of the Netherlands’ largest stadium (now the Johan Cruyff Arena). The project involved translating a complex design into a responsive, cross-browser experience from IE7 upward, with careful attention to performance and accessibility. I collaborated with GX Software on the back-end integration to deliver a cohesive, maintainable build.

Following my personal site’s 2011 Awwwards recognition, Wildlife (a Los Angeles digital agency) commissioned me to build a technically ambitious portfolio experience featuring deep parallax and complex sprite animations. I applied advanced JavaScript techniques to deliver smooth, responsive animations across devices - while preserving visual quality.

The project received FWA and Awwwards recognition for pushing the boundaries of what was possible in the browser at the time.
