I build React and Node.js applications for Cognizant Technology Solutions, supporting enterprise accounting workflows used by 90,000+ users across 40+ locales.
I develop plugins that import business data from Google Sheets, CSV, and Excel, and integrate Google Sheets v4, Drive v3, and OAuth 2.0 through custom authentication and data-transformation layers.
I build secure REST APIs with Express.js, JWT authentication, RBAC, and PostgreSQL, and delivered a UK payroll integration with OpenID Connect SSO, cross-domain iframe messaging, and 20+ payroll and tax report configurations.
I've automated Jenkins and Docker CI/CD pipelines with Playwright, removing 5+ hours of manual testing per release cycle. Outside work, I build and self-host full-stack portfolio, blog, and cloud-storage products on AWS.
