Now — Frontend Developer (SAPUI5 / TypeScript) on a Master Data Governance platform: a Partner Portal for supplier self-service and approval workflows. (12/2024 – present)

Before — Frontend Developer (Vue.js / TypeScript) on an HR SaaS covering organization, timekeeping, payroll and recruitment. (02/2022 – 05/2024)

Earlier — Responsive, mobile-first websites and e-commerce pages from design mockups, including projects for Japanese clients; mentored 3 junior developers. (2014 – 2020)

• Architected a shared OData service layer in TypeScript — new SAPUI5 pages plug in instead of re-implementing API calls
• Built a reusable Vue.js component library shared across HR, timekeeping, payroll and recruitment modules
• Proposed and led an incremental JavaScript → TypeScript migration; contributed to the Vue 2 → 3 upgrade
• Made data-heavy tables smooth with virtual scrolling, lazy loading and code splitting
• Ramped up on SAPUI5 in one week, then onboarded new developers; code reviews as the FE team grew 3 → 8
