- Overseeing and optimizing API integrations with major mobility partners (such as 4411 and De Lijn) and banking partner KBC.
- Providing constructive technical challenge by critically evaluating and redesigning existing structures, such as the transition to separate repositories for individual components.
- Coaching and mentoring less experienced colleagues (such as junior developer Jens) through hands-on guidance during development projects and partner meetings.
- Proactively contributing to process automation, codebase containerization, and the innovative application of generative AI within the software development lifecycle.
- Participating in a weekly rotating "firefighter" schedule to efficiently resolve second-line operational issues and bugs during business hours.
