ERP Modernization & New Features
Enterprise · ManufacturingGlobal Manufacturing / Production & Sales Systems
A large-scale global manufacturing ERP: production and sales management used across 25+ overseas group companies in roughly 20 languages. Over ~6 years I helped move its long-running JSP / jQuery screens to a React + TypeScript SPA, and built new features on top, including a manufacturing-process Gantt chart for visualizing production schedules.
Before
After
What I did
- Migrated complex production, sales, order and inventory screens to React + TypeScript, without losing the existing business logic
- Designed and built most of the shared React component foundation: tables, forms, date pickers and the Gantt chart reused across screens
- Built new workflow-heavy features, including a manufacturing-process Gantt chart for schedules and process dependencies
- Standardized state management for complex forms, search filters, statuses and permissions
- Set the shared UI conventions and component patterns the rest of the team built against
- Supported and mentored other engineers as the React approach spread across a 20+ engineer project
Outcome
Turned scattered legacy screens into a consistent React foundation, cutting duplicated frontend work and making new screens faster to build, without losing the business logic the company had relied on for years.
