Featured Projects

Zero-Downtime Imprivata Platform Migration

Led the migration of a business-critical Imprivata authentication platform by designing and implementing a parallel environment strategy. To minimize operational risk, a complete new backend environment was built, validated, and tested alongside production before executing a controlled cutover. Through close coordination with hospital stakeholders and extensive validation of authentication workflows, the migration achieved maximum data retention while minimizing service disruption.
