1. Software Development Engineer II

   Jun 2021 – Jun 2025

   Harns Technologies · Mumbai, India

   • Owned and shipped the Times of India ePaper platform from scratch to production, part of the Times Group digital ecosystem (10M+ digital DAU, 60M+ app MAU; India's #1 English daily).
   • Extended the ePaper architecture to launch 3 additional regional ePapers on the same platform, with a shared React component library and frontend architecture reused across all editions and a standalone Archive application.
   • Spearheaded Adlob end-to-end, Times of India's unified advertisement booking platform used by 200+ media agencies, built from scratch on React with virtualized calendar inventory grids, campaign creation workflows, and booking management.
   • Resolved a rendering bottleneck on archive views with dense paginated data through list virtualization and lazy hydration, bringing DOM render time from ~20s to under 1s and unblocking the archive product launch.
   • Engineered the ePaper on React with SSR, Context API, Google AdSense, GTM, and analytics integrations supporting ad-revenue monetization; built a text-to-speech reader via the Web Speech API for accessible audio consumption.
   • Delivered advanced multi-keyword archive search across years of historical editions with boolean operators, date ranges, and edition filters, enabling deep content discovery for readers and researchers.
   • Achieved strong Lighthouse and Core Web Vitals scores across ePaper through code splitting, lazy loading, image optimization, and route-level prefetching; drove WCAG 2.1 AA compliance for a mass-market news audience.
   • Migrated a US-based Veterinary SaaS serving 50+ hospitals from a legacy stack to Next.js; delivered core modules of Libsi Markah multilingual e-commerce (payment flow, product pages, cart) on Next.js and Redux Toolkit.
   • Built a custom CMS for podcast and post management, enabling editorial teams to self-serve content publishing and removing engineering as a bottleneck.
   • Mentored and led a team of 5 frontend engineers as direct reports, directing task planning, code reviews, delivery timelines, and growth conversations.
   • Owned on-call coverage during peak-traffic production releases for major national events including general elections and the Union Budget, collaborating directly with engineering leadership and the CEO to ensure zero-downtime delivery.

2. Senior Software Engineer

   Jun 2025 – Present

   Zensar Technologies · Pune, India

   • Own end-to-end frontend for the AAA Digital Dispute Resolution platform, a legal-grade arbitration system for the American Arbitration Association (largest US arbitration administrator, ~88% market share, 180K+ annual cases) spanning case filings, evidence workflows, hearings, and arbitrator verdicts.
   • Architected the multi-step case submission module in React and TypeScript with chunked document uploads, draft auto-persistence, schema-driven validation, and role-based UI states, replacing a fragmented legacy flow and stabilizing the platform's highest-traffic intake surface.
   • Integrated the Claude API into arbitration dashboards with streaming responses and structured prompt design, auto-summarizing 30 to 60 page case documents into expandable navigable briefs, substantially reducing arbitrator first-pass review time and surfacing critical case context within seconds.
   • Shipped a multi-tenant Auth0 SSO platform end-to-end (POC to production) across 3 tenant configurations, with a custom token-exchange layer, Universal Login, RBAC, and tenant-aware routing, now serving as the centralized authentication layer across multiple internal applications.
   • Contributing to a micro-frontend modernization via Webpack Module Federation, enabling independent team deploys, shared runtime dependencies, and incremental migration away from a large legacy monolith without a big-bang rewrite.
   • Migrated legacy build configuration to Vite, reducing build times from approximately 90 seconds to under 20 seconds (4.5x faster) and cutting HMR feedback to sub-second, directly improving team-wide development throughput.
   • Refactored prop-drilled, unstable UI to Zustand with reusable selectors and sliced stores across filters, pagination, and async data flows, eliminating redundant re-renders and stabilizing the highest-churn screens.
   • Established Jest and React Testing Library coverage across filter logic, role-based rendering, and async workflows, preventing regressions during weekly production releases.
   • Drove WCAG 2.1 AA compliance via keyboard navigation, ARIA semantics, focus management, and screen-reader support, critical for legal workflows where accessibility is statutorily required.
   • Conducted 20+ senior-level frontend interviews, led team-wide PR reviews, and mentored junior engineers, directly contributing to hiring quality and delivery velocity.
