Senior Software Engineer

VirtusaBangalore, Karnataka (Remote)

Work and Achievements

  1. Core contributor to a production micro-frontend that powers subscription and billing management across many Intuit products (QuickBooks, TurboTax & more) — serving millions of users globally.
  2. Built & maintained complex, multi-step subscription lifecycle flows (subscribe, upgrade, downgrade, cancel, resubscribe) that needed to work consistently across multiple products, 36+ locales, and multiple payment models — coordinated through multiple team, region-specific rollouts
  3. Reduced bundle size by identifying and removing dead code, unused dependencies, and redundant imports across the codebase — improving load times and build performance by 37%.
  4. Migrated legacy localization infrastructure to a modern localized build system, eliminating runtime overhead of loading all 36+ locale bundles upfront and improving initial page performance by eliminating around 1400+ requests.
  5. Designed and delivered a dynamic widget rendering system that loads UI components at runtime based on product context — eliminating the need for redeployment when integrating with new consumer applications
  6. Owned end-to-end delivery of a deferred plan-change feature involving API orchestration (revoke/confirm patterns), multi-currency handling, conditional blocker screens, and product-specific business rules across multiple product lines
  7. Redesigned the cancellation experience to handle dependent product relationships, bundled SKU logic, and add-on management.
  8. Led React 18 migration for a large, legacy-heavy codebase — upgraded test infrastructure, modernized ESLint rules, and improved TypeScript support
  9. Used AI-assisted development tools (Claude Code, Cursor) to accelerate large-scale migrations and refactoring — helped establish team-wide AI coding standards and workflows

Experience Engineer L2

Publicis SapientGurgaon, Haryana (Remote)

Work and Achievements

  1. Led migration of a legacy Ext JS application to modern React architecture using Redux Saga, Styled Components, and React Hooks — improving maintainability, developer velocity, and user experience across the platform
  2. Owned full module lifecycle end-to-end — from legacy code analysis and client-side business logic validation to development, testing (Jest + React Testing Library), and delivery as a Node-packaged micro-frontend
  3. Championed accessibility compliance (WCAG 2.1 AA) by auditing and remediating accessibility violations across multiple features, ensuring screen-reader compatibility with JAWS and NVDA — directly impacting usability for users with disabilities
  4. Integrated a new pricing engine API across applications with backward-compatible feature toggling between pricing systems, and coordinated technical and go-live releases with cross-functional stakeholders
  5. Built a reusable component library following atomic design principles, improving design consistency across teams and reducing feature development time for new modules
  6. Enforced code quality and security standards through SonarQube integration, achieving high test coverage and reducing production defects
  7. Published and versioned micro-frontend packages to Artifactory, establishing clear documentation and release workflows for the team. Led migration of legacy Ext JS application to morder React architecture using Redux-saga, Context-API, React-hooks & Custom-hooks
