Project : Internal Permissions portal migration

Old portal was running with ASPX framework and had compatibility issues with latest browsers. Portal connects with MS Active Directory to retrieve and maintain user roles

• New portal was developed from ground up using ASP NET web api and Angular 13
• Libraries were re-designed following design patterns
• UI was developed in Angular 13 and used Angular Material concepts to achieve flexible UI controls
• New CI/CD pipeline was setup in TeamCity and deployed on Virtual machines

Project : Oracle 19c migration

Application was using Oracle 12c which had to be migrated due to EOS. We had difficulties due to compatibility issues with latest version

• Piloting approach was proposed to control the backout situation
• Services were controlled to use one of the versions through Assembly redirection. 19c assembly was used in runtime through GAC
• This enabled faster rollback without interrupting application code
• Successfully migrated 19c to all 50+ VM instances in production through scheduled piloting

Standard Project works

• Been introduced to Agile methodology and SDLC
• Proposed a value add solution to save up 40+ 3rd party software licenses by migrating traffic to an independent service
• Contributing dev community with powershell scripts to download project references from JFrog artifactory, updating TeamCity pipeline to publish libraries into artifactory
• Uplifted services and libraries running in 4.5 to 4.7 as the latter version support was withdrawn from MS

Client - Commonwealth Bank of Australia

Project : Windows server migration 2008/12 to 2016
