• Integrate third-party services such as calendar APIs, identity providers (Google, Apple), and payment gateways.
• Contribute to workflow orchestration for multi-step processes, covering event ingestion, state transitions, retries, and error handling.
• Collaborate closely with the product and AI teams to deliver features that drive real-time personalization and user engagement.
• Maintain a strong focus on code quality, performance, and observability.

Requirements
