9+ years building consumer-scale, compliance-driven fintech at Goldman Sachs & enterprise IoT platforms at Siemens Gamesa
Senior Frontend Engineer specializing in React, Next.js, and TypeScript — I build complex regulated user journeys (onboarding, consents, tax compliance, referrals, promotional campaigns) and act as the frontend point of reference for a cross-functional team:
- +2% conversion lift on Marcus.com customer onboarding through iterative UX and flow improvements
- Delivered compliance-critical features — KYC onboarding, customer consents & tax-compliance journeys — meeting the audit and regulatory requirements of a US retail bank
- Test coverage raised from 61% → 80%+ using Jest & Cypress, reducing regressions across releases
- Built @practics/ui, a published reusable React component library (TypeScript, Tailwind CSS)
- Applied WCAG 2.1 AA accessibility standards and web performance optimization (Lighthouse)
- Mentored 2 frontend developers and established React/TypeScript coding patterns through code reviews
- Introduced AI-assisted workflows (GitHub Copilot, Cursor) to reduce boilerplate
- Prior 6-year banking QA background — an edge-case-first, audit-aware approach to regulated fintech
