VisitSync
Clinical operations, made easier to run.
A commercial full-stack platform for independent research sites to coordinate patients, visit windows, protocol workflows and operational reporting.
View live productContext and operational problem
Research sites often coordinate enrollment dates, protocol windows, procedures and follow-up across spreadsheets, calendars and messages. Every manual handoff creates another opportunity for a missed window, inconsistent record or preventable protocol deviation.
VisitSync grew from direct experience managing clinical data, source documentation, queries and audit trails across sponsor and CRO systems. It converts those domain constraints into one traceable operational workflow.
System architecture
What was built
- Patient and study operations
- Protocol templates and automated visit-window calculations
- Procedure and follow-up workflows
- CRM and operational reporting
- SMS and email reminders
- Role-based administration and auditability
Engineering decisions
Server-owned workflow logic
Visit calculations and sensitive workflow rules remain on the server so the interface never becomes the source of truth.
Access at the data boundary
Row Level Security and explicit roles isolate site and study data while versioned migrations preserve controlled schema evolution.
Compliance before convenience
External AI is optional and gated until provider, privacy and data-handling requirements are approved.
Evidence and validation
What I learned
The central lesson was that clinical software cannot simply digitize a spreadsheet. Protocol rules, permissions and traceability must become explicit product behavior. Domain knowledge made it possible to design the workflow before writing the interface.
