Eliminated 3 hours of manual intervention per scan processed.Migrated MRI data from MongoDB to PostgreSQL, resolving schema drift, preserving 100% of the historical data, and enabling detailed insights into lesion size progression and demographic analysis.Implemented Golang and Terratest for AWS infrastructure testing, reducing downtime from IaC deployments by 95% through isolated staging tests and CI/CD feedback loops.Created a GitLab CI/CD pipeline for database migrations, automating schema versioning, backups, test migrations, and data transformations to ensure zero-downtime updates.Deployed a Prometheus, X-Ray, and Grafana observability stack to objectively analyze application performance through real-time monitoring and actionable metrics displayed in dashboards.
