- Design frontend-backend integrations and manage application state using appropriate tools such as TanStack Query, Redux Toolkit, and Zustand.
- Create and maintain unit, integration, and E2E tests using tools such as Vitest/Jest, Testing Library, and Playwright.
- Ensure application performance, caching, and basic security and observability aspects.
- Design asynchronous processes using RabbitMQ or a similar broker - queues, exchanges, routing, retries, acknowledgements, dead-letter queues.
- Actively participate in code reviews, propose improvements, and divide larger functionalities into smaller tasks.
- Diagnose issues in production code and collaborate with QA and DevOps to resolve them.
- Utilize AI-assisted development in daily programming work.
