Work Experience

System Engineer — React.js Frontend Developer

Infosys Limited

Nov 2025 - Present Bhubaneswar, India
  • Serve as the primary frontend engineer for a production-grade bioinformatics dashboard (Genome & NGS modules), built with React.js, Redux Toolkit, and Material UI.
  • Architected and delivered a "My Favourite Projects" feature end-to-end: star-toggle UI on ProjectCard and ProjectListCard, CommonDialog confirmation popups, and localStorage persistence with cross-component synchronisation via custom browser events (favouritesChanged).
  • Implemented filter persistence across page navigations using sessionStorage and localStorage, introducing a centralised utility layer (filterStorage.js/favouriteStorage.js) that eliminated key conflicts across multiple feature modules.
  • Built a suite of reusable MUI components ProjectCard, ProjectListCard, SidebarFilterLayout, NGSSidebarFilterLayout — ensuring consistent design language, accessible markup, and responsive behavior across list and gallery views.
  • Resolved critical UI bugs including unintended card navigation on icon click (e.stopPropagation), Ctrl/Cmd+click new-tab behavior, stale filter state on component remount (resolved via useCallback+ compositekey), reducing reported UI defects and improving overall UX reliability.
  • Managed feature branches in Git within an Agile team, participating in sprint planning, code reviews, and iterative releases with clear component-level separation of concerns.

  • Multi-module React SPA with dynamic sidebar filters, list/gallery view toggling, filter persistence, and a cross-component favourites system.
  • Engineered state synchronisation between sibling components using a CustomEvent pub-sub pattern, removing Redux boilerplate for ephemeral UI state.
  • Resolved a persistent remount bug causing stale favourites display by centralising filter logic in a useCallback-wrapped fetch function with a compositekey prop.
