  • Participating in technical discussions, dailies and planning meetings, and backlog grooming. 
  • Maintaining a mindset of improvement. Open-minded and solution oriented. 
  • Delivering against agreed goals, staying committed and aligned with the team and manager’s chosen direction. 
  • Supporting junior developers through mentoring and lead by example in both quality and attitude.
