- Agile Execution: Lead sprint planning, daily stand-ups, retrospectives, and backlog refinement; deliver predictable increments with high quality.
- Code Quality: Write clean, testable, well-documented code; enforce CI/CD quality gates and architectural guidelines.
- Innovation: Research and integrate new Azure services, patterns, and selective AI/ML capabilities to enhance functionality and efficiency.
- Python Enablement: Use Python for backend services, automation, data processing scripts, or specialized libraries as needed.
