Paras Rawat

I’m a Senior Software Engineer focused on building scalable, maintainable product systems—most recently architecting a modular monolith for a complex React Conversational AI SaaS with 36+ features, enforcing domain-driven boundaries using ESLint.

I improve outcomes with measurable performance and reliability: I boosted Time-to-Interactive by 60% using route-based lazy loading, dynamic imports, and JS bundle optimization, reaching Lighthouse diagnostics (FCP, TBT) and Core Web Vitals (LCP, CLS) with a score of 90.

I also design secure, production-ready capabilities. I developed a fine-grained RBAC authorization system using backend middleware and Redis-cached permission lookups, with route-level guards across 20+ protected frontend routes, and I optimized CI/CD by migrating to a Jenkins-S3-CloudFront pipeline—cutting deployment time from 8 minutes to 4 and improving build artifact availability to 99.9%.

Earlier, I accelerated feature rollout by 40% by architecting a recursive Server-Driven UI engine with versioned JSON schema contracts for 10+ complex UI screens, and I built a configurable coupon Rule Engine that reduced operational setup time by 50%. I back my work with strong quality practices using Vitest and React Testing Library (80%+ coverage and 40% fewer production regressions), and I enjoy challenging problems like CRDT-based collaborative editing and real-time analytics.
