Full-stack Developer in Antwerp, Belgium

I led the build vs. buy decision to switch to a payments platform that would better integrate with Salesforce and deal with our growing pains. The payment platform chosen was Zuora. I migrated the existing payment flows, subscription data, and payment methods from multiple payment providers without hiccups or disruptions to the business.

I built a PostGIS-based search engine that could find qualified drone pilots for specific missions, using equipment data, location, airspace information, and project requirements to create proposals with automated pricing, considering all these factors. This made it much more manageable for the company to organize hundreds of drone surveying missions across four continents. It also helped sales win more opportunities by providing quotes much faster.

I designed a cashless payments API for NFC chip wristbands and various point-of-sale devices at events and festivals. The system was designed to keep operating smoothly during internet disruptions and connectivity issues, which is crucial for remote locations. It also supported various payment providers, allowing event organizers to choose and negotiate rates.

The system is used for festivals and events worldwide, each with tens of thousands of visitors. Customers included Lollapalooza Berlin, Standon Calling, Clockenflap, Oktoberfest Mexico, and Unite with Tomorrowland Barcelona.

I used TypeScript, React, and OpenLayers to build an interactive map-based interface where customers could order drone flights.

Users can indicate the area of interest on the map and select which deliverables they would like, e.g., a CAD drawing to install solar panels. The application saves this information and matches it with a network of qualified drone pilots. It then creates a quote based on the rates of the pilots and the costs of permits, processing, and travel.

I built out the course management system for DataCamp. The features included flows for releasing courses, the Gamification API for collecting XP, and a version-controlled track management system, which allowed the content team to improve learning paths in a data-driven manner incrementally.

I developed the original iteration of this system and, later, led a team to continue making incremental improvements. The system's features allowed the company to increase learner engagement, which helped learners complete more courses while increasing user lifetime value. More than 200 paid courses have been published to 5+ million users using this system.

I built the photogrammetry processing pipeline at Inflights, which automatically processed drone image datasets uploaded to the platform. I wrote the pipeline's processing logic in Python and deployed it to AWS Batch. The processing jobs were triggered by events coming in via Amazon EventBridge and AWS Step Functions.
