A clearer record for the next appointment.
The context
Health context often lives in memory, phone notes, downloaded files, and separate provider portals. Reconstructing a useful timeline during a short appointment adds another burden.
Cassandra explores a patient-owned workspace for symptoms, documents, medications, and appointment preparation. The product organises information and helps users choose what to share; it does not diagnose or interpret clinical results.
I designed and built the private workspace, structured health records, document wallet, and appointment-preparation flows using Next.js and Supabase.
Inside Cassandra
The key workflows, up close.
A health journal gives observations a date, severity, and body context. The aim is to help a person retain the details they want to discuss later.
User-entered observations remain records, not automated medical conclusions.
The appointment brief starts with a date range, relevant observations, questions, and recent changes. Users review and edit what they want to communicate before exporting a concise document.
The output supports a conversation with a clinician while keeping interpretation and clinical decisions outside the application.
Medication and condition records provide continuity between visits. Documents and provider information stay grouped around the person instead of depending on the original download location.
Supabase authentication, storage, and record ownership rules support a private workspace with deliberate sharing.
Dashboard and supporting context views help users review what they have recorded and decide what belongs in the next conversation.
Sharing is specific and user-led. A document or brief can leave the workspace without exposing the whole account.
Behind the interface
The product boundary is explicit: retain and communicate user-entered information without generating diagnoses or treatment instructions.
Per-document sharing, expiry, and access context allow deliberate disclosure of one item instead of a broad account-sharing action.
