- Write quality code: tested, well structured and documented.
- Use AI-assisted development tools to work faster and better, while keeping full ownership of the result.
- Investigate production issues by digging into logs and metrics, and propose lasting fixes.
- Take part in code reviews, Agile rituals and technical discussions with the distributed team.
