At DataArt, I build and scale React and TypeScript applications for a UK grocery e-commerce platform serving millions of active users. I work across catalog, checkout, and payment domains, including multi-tenant, multi-brand modules for seamless storefront deployments.
I've improved business and user outcomes by reducing LCP by 50%, TTFB by 20%, and duplicate API calls by 40%. I engineered resilient Braintree, Apple Pay, and Google Pay checkout flows that contributed to a 10% conversion increase.
I modernize legacy frontend architectures through React, Next.js hybrid SSR, and Express.js BFF layers. I also work with AWS, Sentry, Kibana, security policies aligned with OWASP Top 10, and backend teams on API contracts and schema validation.
Previously at BisonSoft, I built real-time analytics dashboards, reporting tools, and enterprise workflows using React, D3.js, Chart.js, Formik, and Yup. I maintained approximately 95% test coverage while improving performance and refactoring legacy code into modular components.
