Participate in Agile ceremonies, code reviews, technical troubleshooting, and continuous improvement of engineering practices.

Provide Tier 3 technical support for deployed applications and databases, including diagnosing and resolving complex issues in production environments.

Collaborate on release planning, deployment procedures, and documentation (e.g., Jira/Confluence), ensuring transparency and operational readiness.

Support off-hours deployments as needed (evenings/weekends) to meet mission timelines and operational requirements.

Participate in team demos and stakeholder presentations to showcase platform capabilities and progress.
