  • Manage multiple concurrent development initiatives and remove technical blockers.
  • Conduct code reviews and ensure quality, scalability, security, and performance.
  • Troubleshoot complex application and production issues.
  • Mentor developers and provide hands-on technical guidance.
  • Collaborate with Product, QA, DevOps, and other stakeholders to deliver solutions.
