  • Troubleshoot, debug, and upgrade existing software.
  • Participate in the entire application lifecycle, focusing on coding and debugging.
  • Stay up to date with emerging technologies and industry trends.
  • (Optional, if applicable for data analytics focus) : Analyze complex datasets, develop data models, and implement data visualization tools to support business insights.
  • 5+ years of demonstrable professional experience as a Software Developer or in a similar role, with a strong portfolio of completed projects.
