- Write Reusable Code: Focus on building reusable components (like Higher-Order Components) to maintain a consistent design language and a clean, efficient project structure.
- Stay Secure: Implement and follow security best practices to ensure our code is always secure and compliant with EU data regulations for user data.
- Collaborate: Work closely with the CTO and other team members to deliver features at a fast pace. We believe in speed over perfection, and bugs are expected!
