Enterprise Resource Planning For A Multi-vertical Business Group
in Enterprise · ERP
Led a cross-functional team building one ERP platform used across several business verticals, replacing scattered tools with a single system for operations, finance and reporting.
- NestJS + GraphQL services that cut API response times by 35%
- React dashboards for managers and operators
- AWS (EC2, S3, RDS) with zero-downtime deployments

The problem
Each business vertical ran on its own spreadsheets and disconnected tools. Finance reconciled numbers by hand, managers waited days for reports, and nobody had one trusted view of operations.
What we built
- A modular NestJS + GraphQL backend where every vertical shares core entities (customers, inventory, invoices) but keeps its own workflows
- Role-based React dashboards so operators, managers and finance each see exactly what they need
- Reporting built on PostgreSQL views, so figures come from one source instead of exported sheets
- AWS infrastructure (EC2, S3, RDS) with CI/CD and zero-downtime releases
The result
- 35% faster API responses after query and resolver optimisation
- One platform replacing scattered tools across verticals
- Reports available on demand instead of assembled by hand
- Weekly releases without taking the system offline
