Work Experience

Software Development Engineer I \u2014 Frontend

Calance Software Pvt. Ltd.

Jun 2024 - Present Gurgaon, India
  • Built the Ujjain Simhastha 2028 Crowd-Flow Forecaster, an end-to-end crowd-management product for a 40\u201350M gathering - OSM-routed simulator, LEA/CDR-schema synthetic TSP feed, H3 ETL, capacity physics & evacuation max-flow solvers, and a ConvLSTM density+velocity forecaster (5/15/30/60-min) on a real-time dashboard.
  • Built an EdTech learning platform (Next.js 14) a perfect Lighthouse 100/100 (FCP 0.6s, LCP 0.8s, CLS 0 ) via Partial Prerendering (PPR), ISR, React Suspense streaming, and per-route code splitting; shipped a themeable, WCAG 2.1 AA-accessible component library (dark mode) with SEO-optimized routes, lifting session duration 22%.
  • Owned the Calance Career Portal frontend (React.js PWA + Node.js BFF), engineering offline-first Service Workers that cut drop-off 38%, Intersection Observer infinite scroll, Web Worker-offloaded parsing, and TanStack Query optimistic caching that reduced perceived latency 55% for 2K+ concurrent users.
  • Architected the AI Product Planning SaaS UI (Next.js 14) with a real-time streaming (SSE) document interface and virtualized lists; enforced TDD (Vitest + React Testing Library, 95% coverage) and stripped 45% of bundle weight via tree-shaking and dynamic imports, sharply improving time-to-interactive.
  • Delivered a Workflow Automation Platform (Next.js App Router) on a Server-Driven UI architecture with a drag-and-drop builder, enabling zero-frontend-deploy rollouts; enforced strict MVVM and Zod runtime schema validation, eliminating 100% of runtime type errors in production.
  • Shipped a Lease Management System (Angular 17 RxJS) with offline-first IndexedDB and HTTP Interceptors for zero data loss, interactive data-viz charts, and Reactive Forms validation layer that cut invalid submissions by 84%.
  • Optimized a React Native E-commerce App (Redux Toolkit + Stripe) for 50% faster FlatList rendering via windowed virtualization and memoized selectors, fluid Reanimated gestures/transitions, and FastImage progressive loading that cut image memory 35% and crashes to under 0.2%.
  • Spearheaded a company-wide design system and Storybook component library (40+ theme-tokenized, accessible components) adopted across 5+ apps, standardizing UX and cutting new-feature UI build time by 30%; added visual regression testing to prevent UI drift across releases.
  • Built a real-time analytics dashboard streaming live metrics over WebSockets into interactive D3 / Recharts charts with virtualized tables, debounced filters, and CSV export, sustaining smooth 60fps updates under high-frequency data.

Projects

Self-Healing RAG

Node.js (NestJS)Vector DBLLM APIs
  • Built a self-healing RAG engine with a multi-strategy AI Judge (Faithfulness, Context Precision/Recall, Groundedness) that scores every response and, below threshold, runs a diagnostic engine to identify and re-run only the failing stage (query rewrite, hybrid BM25 + vector RRF retrieval, rerank, or generation), cutting wasted recomputation.
