Mohit Purohit

Frontend Engineer with 4 years of experience engineering production-grade web applications using React.js, Next.js 14, TypeScript, and modern frontend technologies. Engineered scalable UIs serving enterprise-level traffic, achieving 40% UI latency reduction and Lighthouse score uplift from 60 to 88+. Specialize in scalable component systems, SSR/SSG/ISR rendering architecture, and micro-frontend design patterns — delivering measurable Core Web Vitals improvements (LCP −2s) and SEO uplift.

Full-stack fluency across Node.js/Express/NestJS, MongoDB, Redis, and AWS, enabling independent end-to-end feature delivery. Co-authored frontend HLDs, drove code quality standards, and collaborated cross-functionally with product, design, and backend teams across two Fortune 500 engagements.

(2022-02 - 2025-10)

Client: GE Healthcare — Enterprise Healthcare Platform

• Architected a feature-based frontend monorepo with atomic composition patterns, reducing cross-team code duplication by ~35% and enabling 3 squads to ship independently without merge conflicts or shared-state regressions.
• Cut UI latency by 40% (p95: 3.2s → 1.9s) by profiling and eliminating 60+ redundant renders via React.memo, memoization, and surgical context partitioning.
• Led full SSR/SSG migration of 8 critical user flows in Next.js 14, improving LCP by ~2s and lifting organic search impressions by 22%.
• Spearheaded decoupling of REST API integrations using Factory and Strategy design patterns, reducing service-change blast radius by 50% and enabling A/B testing without frontend deployments.
• Refactored complex state flows into isolated, predictable data layers using React Query and context partitioning — improving cache consistency and cutting debugging cycles.
• Built fault-tolerant UI error architecture with exponential-backoff retry, Suspense-boundary fallbacks, and graceful degradation — maintaining 99.5% perceived uptime across unstable API conditions.
• Configured GitHub Actions CI/CD pipeline with automated Lighthouse regression gates and staged canary rollouts, achieving zero-downtime deploys across 4 environments.

Client: HDFC Ltd. — Financial Services Dashboard

• Published 12+ shared custom hooks (useAuth, useForm, usePagination) consumed across 5 modules, reducing per-feature boilerplate by ~40%.
• Designed scalable frontend folder structures and component composition patterns improving maintainability across a large-scale financial codebase.
• Hardened application security surface with JWT-based auth, RBAC route guards, and CSRF-token lifecycle management — passing third-party security audit with zero critical findings.
• Co-authored frontend HLD for the HDFC dashboard, defining CSR/SSR rendering strategy, API layer contracts, and component boundary standards — adopted as the team's engineering baseline.
• Optimized high-frequency input handlers with 300ms debounce, leading-edge throttle, and React 18 transition batching — reducing render overhead by ~28% on search-intensive pages.
