01.2025 - Current
- MFE Platform: Architected IRCTC's Micro-Frontend platform from zero (Vite Module Federation + Turborepo) - 6 independently deployable verticals, 6-engineer team, zero shared deployment dependencies; eliminated cross-team release conflicts and enabled parallel feature delivery for the first time.
- Train Booking: Owned the highest-traffic module end-to-end - seat selection, PNR flow, coach layout, fare calculation, and booking confirmation - integrated with live IRCTC APIs via React Query, serving ~2M daily booking sessions.
- Add-to-Cart & Trip Planning: Built multi-modal journey bundling (train + hotel + cab) into a single cart flow - first time IRCTC exposed cross-vertical booking in one session, unlocking a new revenue surface.
- AI Chatbot MFE: Shipped a natural-language booking assistant for train search, PNR status, and booking queries - integrated with a Node.js backend API, deflecting repetitive support queries from static help pages.
- Auth System: Implemented JWT-based auth with cross-MFE state sync via custom DOM events and persistent session management - zero auth regressions across 6 federated verticals post-launch.
- Shared UI Package (@irctc/ui): Published 20+ reusable components, custom hooks (useCart, useTokenRefresh), and auth utilities - adopted by all 6 MFE teams as the single source of truth for UI consistency.
- CI/CD: Configured Docker multi-stage builds and GitLab pipelines deploying to Kubernetes with environment-based remote entry URL injection - production config changes deployable in under 2 minutes with zero code changes.

- India's largest railway ticketing platform

- Eliminated 3 unnecessary re-render chains across the credit dashboard's most complex component tree - measurably improved responsiveness of the platform's highest-traffic view.
- Architected and shipped a 20-component reusable UI library from zero within a 6-engineer frontend team - standardised design-system implementation across all product surfaces, eliminating ad-hoc duplication across the codebase.
- Replaced ad-hoc fetch logic with a React Query-driven data layer for credit score and financial insights endpoints - introduced stale-while-revalidate caching, cutting redundant network requests on every dashboard load.
- Built interactive credit-score trend visualisations and financial health breakdowns - the clearest data-driven view of credit trajectory shipped on the platform to date.
- Introduced AI-assisted development workflows (Cursor, Claude) for PR review, refactoring, and test generation - reduced review turnaround and surfaced edge cases earlier in each sprint.

- Credit monitoring, financial product comparisons, personalised credit management
