Work Experience

Software Developer

ParentPay Ltd

Jan 2026 - Mar 2026 Pune
  • Implemented pixel-perfect, responsive Figma-to-production UI components across bi-weekly sprints — consistent design language, zero post-release defects in assigned features.
  • Built end-to-end Exam Seat Allocation feature using React.js + TypeScript, replacing a manual spreadsheet process and reducing administrative overhead significantly by reusable component composition pattern.
  • Designed dynamic Result Publishing interface with real-time data rendering; applied React Query caching and background refetching to cut redundant API calls and improve perceived load time on slow connections.
  • Collaborated with Delivery Manager and Product Owner in Agile ceremonies — backlog grooming, sprint planning, and demo presentations; flagged technical constraints early during design reviews.

Software Developer

Laminar Aviation InfoTech

Nov 2022 - Dec 2025 Mumbai
  • Architected reusable shared component library adopted across 5+ enterprise modules — enforced shared component patterns, reducing new-feature development effort significantly and maintaining page consistency ensured cross-browser Compatibility across chrome. Firefox, safari.
  • Improved initial load performance via route-based code splitting (React. Lazy + Suspense), lazy loading, and asset optimisation — measurably faster first-paint and improved Core Web Vitals on target hardware.
  • Built internal Gantt chart React component with drag-and-drop rescheduling and nested task dependencies; implemented virtualisation (react-window) for data-heavy rostering dashboards handling 10,000+ rows without scroll lag.
  • Developed ATSM (ATC Staff Management System) frontend as sole architect using React.js + Redux Toolkit — scalable state architecture, complex shift scheduling workflows, and virtualised data grids.
  • Refactored async data layer with Redux Toolkit + Async Thunks and structured error handling — reduced uncaught API errors in production logs.
  • Optimised large data grid rendering using React. Memo and useMemo — eliminated UI jank and unnecessary re-renders measured via React DevTools Profiler.
  • Built Node.js + Express.js REST API endpoints for shift scheduling and roster management with JWT-protected routes and MongoDB integration.
  • Built unit and integration test suite (Jest + React Testing Library) with strong coverage on critical rostering flows — caught regressions before QA on every sprint.
  • Conducted code reviews, provided constructive feedback to junior developers, and contributed to improving team coding standards and best practices.
