  • Participating actively in Agile ceremonies including sprint planning, backlog grooming, and retrospectives. Maintaining a well-prioritized product backlog and providing accurate effort estimates to support on-time, within-budget delivery.
  • Creating and maintaining comprehensive technical documentation in accordance with SDLC and organizational standards.
