Karan Soni

I’m a Senior Engineer II at Samsung R&D Institute (Bangalore) with 3.5+ years of experience building enterprise UI and SDN cloud solutions. I architect React/Redux applications with Redux Saga and drive performance outcomes like 35% faster UI load times through lazy loading, code splitting, and bundle optimization.

I focus on production-grade front-end engineering: I built a browser caching library using Service Workers and IndexedDB, improving cache hit rates by 45% and reducing API calls by 30%. I also integrated AWS Cognito MFA with secure OAuth 2.0 flows and JWT token management, then automated deployments using AWS CDK (Infrastructure-as-Code) and CI/CD pipelines.

Before that, I led UX and performance work using React and TypeScript, reducing bug reports by 47% and cutting page load time from 4.2s to 1.8s after modernizing legacy jQuery across 30+ screens. I strengthen reliability with testing (Jest with 85% coverage, plus Cypress and axe-core for accessibility) and I enjoy building products too—like a real-time geo-fencing React Native app with Firebase that improved tracking accuracy by 15% and reduced false alerts by 25%.
