Customers
Tenant-scoped records with simple, inspectable workflows.
The customer area keeps routine operations flat while still respecting workspace boundaries, authorization checks, and deletion rules once invoices reference a contact.
Backend portfolio project
Production-minded accounting demo built to showcase backend engineering skills.
A realistic business application focused on domain rules, data integrity, authorization, auditability, and pragmatic product execution.
Multi-tenant
RBAC
Audit trail
SQL constraints
Tests
Docker ready
Not another CRUD tutorial.
Built around the backend decisions reviewers actually look for.
Ledger Forge models tenant boundaries, RBAC, invoice lifecycle rules, audit trail failure modes, and database constraints in a compact product surface that is easy to inspect.
Invoices
Domain rules where the product risk is real.
Draft editing, lifecycle transitions, server-authoritative totals, and audit history are handled as business behavior instead of UI state.
Engineering focus
Small surface, serious backend shape.
Domain rules
Invoice totals, status transitions, and mutation guards live server-side.
Authorization
RBAC abilities are checked in context, not inferred from routes alone.
Data modeling
PostgreSQL constraints and Drizzle schemas keep tenant data explicit.
Reliability
Audit trail degradation blocks risky writes while preserving reads.
Testing mindset
Unit, integration, route, and browser suites cover different failure modes.
Product execution
The UI exists to make backend behavior visible and reviewable.
Stack
TypeScript from route to database.
A compact full-stack surface built around typed server behavior, relational data, and inspectable UI flows.
