I’m a Senior Frontend Engineer with 5+ years of experience building high-performance, accessible, and scalable large-scale Single Page Applications (SPAs). I focus on delivering great user experiences through performance optimization, strong frontend architecture, and maintainable systems.

In my recent work, I led the frontend modernization of a CRM platform by architecting a scalable micro-frontend architecture using single-spa for independent feature team deployments. I engineered a shared React.js & TypeScript component library that reduced UI development time by 30% while ensuring WCAG compliance and design consistency across applications.

I also build quality into the workflow: I implement comprehensive testing strategies (Jest/React Testing Library for unit tests and Playwright for E2E) and integrate them into CI/CD pipelines to prevent regressions. For performance, I’ve optimized SPA rendering and large-scale data handling—reducing Largest Contentful Paint (LCP) by 40% through code-splitting, lazy loading, and efficient state management.

Earlier, as a Marketing Cloud Consultant/Developer, I architected and developed full-stack Next.js applications to extend Marketing Cloud functionality, including custom CloudPages blocks and interactive personalization experiences. I integrated secure REST API flows to trigger targeted journeys (expanding audience reach by 30%), improved email production with Next.js-based automation (cutting production time by 25%), and built a dataset microservice that improved data accuracy and boosted campaign ROI by 25%.
