- Design resource‑oriented APIs and apply integration patterns such as REST, event‑driven architecture, and queue‑based communication.
- Manage and align stakeholders—including senior leadership, RTEs, architects, and development teams—by communicating architectural rationale, deviations, and risks.
- Establish and enforce architectural governance through standards, policies, automation, and regular reviews.
- Mentor and coach senior engineers, promoting best practices and fostering a culture of continuous learning.
