- Apply RxJS and reactive programming patterns to handle async flows and state management.
- Work with messaging systems (RabbitMQ) to support asynchronous, event-driven communication.
- Use logging, search, and observability tools (Elastic stack or similar) to improve system visibility and reliability.

- Ability to reason about code quality, performance, and best practices, not just write code.
- Comfortable discussing architecture and real-world trade-offs, especially in microservices contexts.
- Advanced English for technical discussions with international teams.

Nice to Have:
- Experience with platform or shared-services architectures.
-Exposure to microservices and distributed systems.
