Outcomes
- Multi-user auth with role-based permissions (3 roles)
- Internal tool now used daily by 30+ operations team members
- Replaced 4 separate spreadsheets and a Notion database
- Saves ~120 person-hours per month across the team
The situation
An operations lead used Cursor to build a dashboard that pulled data from their inventory system, shipping API, and CRM into one view. It worked beautifully for them. The problem: it had no real auth, no permissions, and they needed 30 teammates to use it.
The audit
The audit found the dashboard was solid as a single-user tool but had architectural gaps for multi-user: no real session handling, all data was scoped to a single user ID hardcoded in environment variables, the deploy was a personal Vercel project, and no error monitoring. Schema needed extension for roles and audit logs.
The work
Migrated to Supabase Auth with magic link signin. Added role-based RLS policies for admin, lead, and viewer roles. Rebuilt 6 data queries to be user-aware. Set up a team Vercel project with proper env management. Added Sentry for error monitoring and PostHog for usage analytics so the founder could see what features were actually used.
The result
The tool is now the daily home base for the operations team. The lead estimated it saves the team 120 hours per month relative to the spreadsheets and Notion docs it replaced. Six months later the team is still using it, with two follow-up scope additions to expand functionality.
“I built the v1 in a weekend with Cursor and it was great for me. Going from one user to thirty was a different problem and I was not the right person to solve it. FinishLine made the leap feel boring, which is what I wanted.”
