6 report types × PDF + Excel: P&L, Expense Breakdown, Vendor Payment, Govt Audit, Investment Portfolio

3 roles (OWNER · ACCOUNTANT · REVIEWER) with proper access control

Safe file handling so a failed save never leaves an orphaned document behind

Independent per-section dashboard queries, so one broken endpoint doesn’t blank the screen

  5. Project 07 Identity & Auth · Client Work 2024

    Identity Infrastructure

    Shared dual-IdP OAuth infrastructure (Keycloak for local dev, AWS Cognito for staging/prod), consumed by both WhatsNextPlease and the HCC CRM platform. A custom wnp_role attribute flows through both providers so downstream services see one consistent role claim regardless of which IdP authenticated the user.

React frontend hardcoded port 8080: changing the PORT env var disconnected frontend from backend silently.

Root causeVite requires VITE_ prefix; no bridge between Go’s root .env and the frontend build

program.go reads root .env, extracts PORT=, writes VITE_PORT to frontend/.env at generation time; app.tsx.tmpl uses import.meta.env.VITE_PORT.

- fetch('http://localhost:8080/')
+ fetch(`http://localhost:${import.meta.env.VITE_PORT}/`)
