Client Portal · Two Deployments · ~10,000 Employees Each
- Problem
- A high-value client posted their contract for bid. No online portal existed that met their needs, and the timeline was weeks, not months.
- What I Built
- A client portal built from scratch: five user role personas, multi-factor authentication, user-managed content and a security architecture built for an employer expecting enterprise quality. A second deployment followed for another client with its own branding, plan rules and customizations.
- Outcome
- Shipped in six weeks and the client stayed. Two deployments now serve roughly 10,000 employees each, and the codebase became reusable infrastructure rather than a one-off rescue.
