• Support data ingestion, transformation, and validation workflows in coordination with data engineers, AI engineers, and functional SMEs.

• Build reusable front-end and back-end components that can support future enhancements and related Guidehouse delivery efforts.

• Participate in system design, sprint planning, code reviews, testing, deployment readiness, and user acceptance activities.

• Implement automated testing, CI/CD practices, documentation, logging, monitoring, and error handling to support production readiness.

• Troubleshoot defects, performance issues, integration challenges, and user experience gaps across the full application stack.

• Collaborate with stakeholders to translate functional requirements into technical designs and working software.
