- AI-Augmented Development: Use AI coding assistants to accelerate development, validate output against quality standards, and share effective AI practices with the team.
- Testing & Quality: Design and execute testing strategies (unit, integration, acceptance), participate in code reviews, and resolve frontend issues independently.
- Debugging & Troubleshooting: Identify and resolve frontend issues and bugs efficiently.
- Continuous Improvement: Stay current with frontend technologies, OutSystems updates, and emerging best practices. Participate in Agile/Scrum ceremonies and team retrospectives.
