My roleAuthentication migration lead
Overview
A Singaporean consultancy needed its authentication system migrated to meet updated Singpass requirements while supporting daily users.
Project statusDelivered authentication migration
Scope
An authentication upgrade for an existing consultancy system in Singapore. I directed the migration and security remediation while the system continued to serve daily users.
Main features
Security remediation
Resolve five critical security vulnerabilities as part of the migration. Implementation and vulnerability details remain private.
Continuity for daily users
Deliver the upgrade for a system serving more than 250 users daily, with reported uptime of 99.9%.
Technology
React & Redux
Existing web application and client-side state.
Material UI
Interface components in the application being migrated.
AWS Amplify
Existing frontend cloud integration.
Python & AWS CDK
Backend infrastructure defined in code.
These technologies describe the host application. Authentication configuration, protocol details and client-specific implementation are intentionally omitted.
Engineering approach
Upgrade within an existing system
The migration had to fit the application already used by the consultancy, combining requirement changes with security fixes and operational continuity.
Report outcomes without exposing the weakness
The case study records the remediation count and service outcome while keeping exploit details, identifiers and system configuration private.
