- Building our native companion app with Expo / React Native or Swift.
- Building features across the stack, from the user interface to the database with Prisma and PostgreSQL, and the Python services behind them.
- Owning features end to end: turning customer needs into requirements, shipping them and checking that they help.
- Applying DevOps practices to support development and deployment, including Docker and, when appropriate, Kubernetes.
- Participating in technical discussions, code reviews and architectural planning.
