Kajal Jansari

I’m a Senior Frontend Developer with 5.5+ years of experience building scalable, high-performance web and mobile applications. I focus on React.js, React Native, and TypeScript to ship products that feel smooth, reliable, and secure.

Across 10+ production releases, I’ve delivered 30% faster development cycles, 25%+ performance improvements, and 90%+ test coverage. I build maintainable systems with modular architecture and reusable components to reduce crashes and improve stability.

My technical strengths include state management (Redux, Zustand, Context API), REST APIs, GraphQL, and Firebase. I also apply production-grade security and performance practices—OAuth 2.0/OIDC, biometric login, SSL pinning, encryption, plus web performance optimization like lazy loading, code splitting, and memoization. I’m mindful of accessibility using WCAG 2.1/a11y best practices.

I enjoy raising team quality through mentoring, code reviews, and Agile/Scrum delivery. From cross-functional healthcare to SaaS and enterprise environments, I collaborate closely, improve velocity by 25%, and consistently deliver on-time releases while strengthening scalability and maintainability.
