Software Engineer III @ Notch

Designed and developed payment processing systems, including PDF generation APIs for customer invoices using cloud functions and React applications
Led the architecture and development of the AP/AR product platform’s main company application, building robust Node.js APIs and Typescript React frontend systems with OCR capabilities, processing thousands of invoices monthly
Implemented an OCR bills editor with real-time collaboration capabilities, enabling seamless bill validation and integration with financial third-party systems
Developed responsive customer portals and supplier dashboards that improved mobile user interactions
Led the development of a shared UI component library, ensuring design consistency and reducing development time
Implemented comprehensive unit testing across the codebase, achieving high code coverage in critical systems
Migrated native applications to web iOS/Android apps using Capacitor, significantly reducing time-to-market and enhancing developer efficiency
