What I'm looking for

I’m looking to lead frontend teams building high-performance, accessible product experiences—ideally in FinTech/AI—where I can architect shared components, own platform migrations, and ship AI integrations with strong UX standards.

I’m a Lead Frontend Engineer with 7+ years building enterprise-grade, accessible, and high-performance web applications in FinTech. I’m expert-level in Angular, with deep specialization in AG Grid, NGXS, WCAG 2.1 AA accessibility, and shared component architecture.

At DiligenceVault, a FinTech SaaS for global institutional investors, I architected 15+ major platform features end-to-end and created 20+ shared components from scratch, while driving platform-wide accessibility and UX standardization across 5,500+ commits. I also maintain a rare AngularJS ↔ Angular hybrid codebase, and lead i18n across English and Japanese locales.

I build with practical engineering and measurable outcomes—like a Claude API-based AI Report Narrator with three tone modes and live demos, plus a platform-wide WCAG 2.1 AA initiative with custom keyboard navigation, ARIA, and focus management (216+ commits). I’ve led complex UX flows, implemented Web Workers for heavy Excel processing, and delivered UTC/locale-aware date formatting via shared pipes across modules.
