• * 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.
