Enabled safer staffing and allocation management by delivering full-stack Allocation workflows for create, edit, transfer, and soft-delete operations, using React, TypeScript, Kotlin, Spring Boot, PostgreSQL, Flyway, and REST APIs to preserve allocation history and enforce validation rules. Improved staffing decisions by building Allocation Opportunities and SkillFinder workflows with React tables, filters, modals, side panels, shared Axios services, badge-based search, and backend availability calculations for capacity limits, project conflicts, expired allocations, and first available dates. Automated allocation communication and improved planning visibility by implementing schema-backed notification roles, rules, recipients, async Spring email events, and React timeline/Gantt schedule views with project date rendering and day, month, quarter, and year ranges.
