Cover image for Internal tools and system integration
Login with multi-role permissions, database design and data migration, admin dashboards, reports and exports, third-party integrations, scheduled automation.
If the system touches personal data, I build row-level isolation, encryption of sensitive fields and an audit trail into the spec from the start, not after something goes wrong.
I have already shipped this pattern to production: a multi-tenant SaaS for a 16-campus tutoring chain, 476 active students and 63 users, where each tenant is isolated at the database layer with PostgreSQL row-level security.
Timeline from three weeks depending on scope. Scope is written down and agreed before any work starts, so there are no surprises halfway through.
