/ THE STORY

The product

A multi-tenant payroll and operations platform serving a US solar SaaS company and their downstream installer network. Onboarding, training, rate classes, campaigns, payroll runs, scheduled tasks — all governed by role-based access control on top of a Material Dashboard themed .NET MVC stack.

Why plugins

Different tenants need different integrations and workflows. A monolith with feature flags becomes a nightmare. We designed the platform as a modular .NET host with a plugin marketplace — each plugin can contribute its own menu items, EF Core migrations, permissions, and routes. Tenants install only what they need, hot-reloadable without redeploying the host.

What I shipped

Plugin architecture (lifecycle, marketplace UI, install/activate/update flow, per-plugin migrations), CRM import plugin, background check plugin, payroll clawback plugin, and the team leader / director role permissions matrix. Working directly with the founder (CTO-level) on a focused-execution cadence.

/ HIGHLIGHTS

What stands out

  • ✓ Plugin marketplace with install / activate / update / uninstall flow
  • ✓ Per-plugin EF Core migrations and menu contributions
  • ✓ Permission-gated UI driven by database-backed RBAC
  • ✓ CRM data sync plugin eliminates manual data entry
