  • Implement publish/subscribe async messaging and handle distributed transactions using saga or orchestration patterns.
  • Design and consume REST APIs, webhooks, and subscription APIs, while actively contributing to API contracts and versioning.
  • Integrate LLMs into services (function/tool calling, structured outputs, and the Model Context Protocol) and build agentic workflows, ensuring AI safety and governance (guardrails, PII/PCI handling) in a regulated setting.
