Jan Stevens

I’m a full-stack developer based in Antwerp, captivated by technology and problem-solving. My experience spans across 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 Sales 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).

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.

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 to a fully functional application. I think critical about how components should hook together and keep them easy to understand. Recently my focus shift to become a Full stack developer leveraging AWS and serverless.

Monster Mirror


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 With DASH7 Technology


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.
