Multi-tenant SPM/PPM SaaS (Django 5.2, DRF, PostgreSQL)
- 🔧 Config-driven calculation engine — replaced hard-coded business logic with 220+ database-defined formulas, using AST-based safe evaluation, a pluggable data-provider registry, and dual collection modes — behavior adapts per tenant without code changes
- ⚡ Cascading recalculation engine — field-level change detection propagates only to affected dependents (with depth limiting), paired with reverse-dependency mapping and auto-built prefetch to eliminate N+1 queries
- 🌲 Generic tree API — tenant-aware registry, automatic prefetch-depth detection, and cross-worker cache invalidation consolidating multiple bespoke endpoints into one configurable service
- 🔐 Declarative row-level access-control layer — single configuration map secures any model, enforcing role-based visibility across the data model without per-endpoint code
- 📊 Declarative dashboard-card framework — multi-stage, multi-layout cards bound to the calculation engine with bulk-fetched results and tenant-scoped caching
- 📈 Performance profiling — optimized ORM usage, query prefetching, and caching across core modules using Django Silk
