Regular code reviews, feedback sessions, and mentorship to junior developers, ensuring code quality and knowledge sharing.
Weekly or sprint-based status updates on development progress, blockers, and delivered functionalities.
Timely resolution of production issues, regression fixes, and performance improvements based on user feedback and testing.
Available for any on-call on weekend for production issues.
