01 / Context
A document workflow built for everyday use
Claim Shark DMS is a document workflow platform designed to make document-heavy work easier to navigate. Its capabilities include advanced search, in-browser PDF viewing, text extraction and metadata analysis.
The work included carrying a legacy Angular application forward through a major framework upgrade while keeping the core document workflows usable and maintainable.
02 / Challenges
Modernise without losing the workflow
02
Document handling
Keep document discovery, PDF viewing, extracted text and metadata useful within one workflow.
03
Reusable capability
Create a reusable document-viewer library that other parts of the organisation could use instead of rebuilding the same capability.
04
Responsive performance
Use application modernisation and server-side caching to improve responsiveness and reduce repeated backend work.
03 / Approach
A modern Angular foundation
01
Upgrade the application
Advance the legacy Angular 10 application to Angular 17, working through major-version changes and aligning dependencies with the updated framework.
02
Support document discovery
Bring advanced search, text extraction and metadata analysis together with in-browser PDF viewing to support document-focused tasks.
03
Reuse the viewer
Package document-viewing functionality into a reusable library to reduce repeated implementation work in downstream applications.
04
Improve backend efficiency
Use server-side caching where appropriate to reduce repeated processing and improve response performance.
