Antwerp, Belgium
I’m a full-stack developer based in Antwerp, captivated by technology and problem-solving. My experience spans various software technologies including React, Node.js, Rails, Ruby, Postgres, GraphQL, and Elixir.
I’m a versatile developer who quickly adapts to new technology and effectively applies it in production. My projects range from building full-stack applications to cross-compiling Android for ARM Point of Sale devices. At PlayPass, I developed access control software for festivals like Rock Werchter and large venues such as Sportpaleis. At November Five, my focus shifted towards frontend technologies, and I became an advocate for Serverless architecture. Using React, we transform designs into interactive frontend applications powered by Serverless backend for frontends (BFF). Currently at Spencer, I work as a Senior Full Stack Engineer, building React applications and AdonisJS backends while contributing to infrastructure automation on AWS.
In my free time, I enjoy culinary classes at Piva and swimming. As a typical Belgian Burgundian, I appreciate good food paired with a glass of wine. My personality can be described as straightforward with a dash of sarcasm.

As a Senior Full Stack Engineer, I work across the entire technology stack, building and maintaining multiple applications and services. My responsibilities include developing React-based frontend applications including the backoffice admin interface and customer-facing web applications, building robust backend services using AdonisJS and TypeScript, and contributing to infrastructure automation using Ansible and Terraform on AWS. I also develop Capacitor plugins for mobile applications, work on authentication and identity services, and maintain CI/CD pipelines to ensure smooth deployments across environments.

We leave our clients with more than products. By building meaningful relations throughout their organisation, we transform them from within and ensure we live and breathe digital together.
As a frontend React developer, I transform the designs into fully functional applications. I think critically about how components should hook together and keep them easy to understand. Recently, my focus shifted to become a Full Stack developer leveraging AWS and serverless.

My job was to work on the location estimation of small birds for the nature department, based on DASH7 Wireless technology and custom tags. Using the received signal strength the birds could be located. Research included antenna design optimisation and embedded software development.

Monster Mirror enhances your Gloomhaven boardgame journey by providing a convenient way to view monster ability cards. Designed as a companion app, it seamlessly integrates with the physical monster ability cards rather than serving as a replacement. This ensures a streamlined and complementary experience, preserving the tactile engagement of the original game components.
Robot localization needs to be solved in order to use the robot for other purposes. In this paper, we examine the feasibility of DASH7 tags, operating on the 433 MHz unlicensed band, for locating mobile robots in domestic environments. We achieve the same level of accuracy as laser range finder based localization, while using less processing power. Our results indicate that DASH7 can be used for robot localization, solving the robot localization problem.
