Clinical / Healthcare
Workflow-driven clinical application with role-based access, dashboards and enterprise integrations.
Clinical operations teams needed a single application to manage structured records and multi-step review workflows that were previously handled across spreadsheets, email threads and disconnected internal tools. The process had strict rules about who could see and change what, and at which stage.
A web application with an explicit workflow model: each record moves through defined states, each transition is permitted only for specific roles, and every change is recorded. A React front end handles data entry, review queues and dashboards; a .NET Web API enforces the rules and persists to SQL Server; enterprise identity provides sign-in and group membership.
A simplified, public-safe view of how the pieces fit together.
Client
Role-aware UI, forms, review queues, dashboards
Identity
Sign-in, tokens, group membership
API
REST endpoints, validation, authorisation
Domain
State transitions, permission checks, audit
Data
Relational schema, stored procedures, reporting queries
Early on, the UI hid actions the user could not perform while the API re-implemented the same checks separately. The two drifted. The fix was a single server-side authorisation model, with the API returning the allowed transitions for each record so the UI renders from that rather than duplicating the logic.
Aggregate views written as straightforward queries were fine at demo volumes and slow in production. Reading execution plans pointed to missing covering indexes and per-row subqueries; restructuring the aggregates and adding the right indexes brought them back into an acceptable range.
Workflow rules changed as the process matured. Records already in flight had to remain valid, so transitions were versioned rather than rewritten, and migrations were written to be reversible.
A process that previously depended on manual coordination ran inside one application with defined roles, states and visibility. Specific business metrics are confidential and are deliberately not published here.
