Contribute to system design and architecture discussions, particularly around modularization, scalability, and observability.
Collaborate with developers, product managers, and stakeholders to deliver high-reliability features and fixes.
Help build internal knowledge by documenting system behaviors, edge cases, and refactored components.
Potentially lead the gradual refactoring and modernization of legacy code to Modern C++.
