Senior Software Developer at Commencis building Transavia booking, check-in, and payment journeys with React Native.

Message

At Commencis, I own the technical design and implementation of React Native features for Transavia, taking them from product requirements through release. I build booking, check-in, and payment journeys using REST APIs and WebView integrations.

I also define reusable component patterns and Redux Toolkit approaches, review pull requests, and troubleshoot production issues. For analytics, I implement and validate consent-related event tracking with Firebase Analytics, GA4, and Snowplow.

As a freelance developer, I built mobile and web applications and backend workflows, and integrated generative AI and vision APIs into application workflows. Earlier, I built browser-based games at Infinity Games and delivered data-oriented web applications at Londonist Technologies.
