· Write reusable, scalable, and high-performance server-side code.

Integration & Automation

· Interact with external APIs and databases to fetch/store data.

· Implement authentication flows (OAuth, Azure AD preferred).

· Perform unit and integration testing using tools like xUnit/NUnit.

· Optimize performance and ensure cross-version compatibility across Office desktop & web.

Collaboration

· Participate in code reviews, sprints, and daily standups.

· Contribute to documentation, architecture discussions, and technical improvements.
