React JS Developer
Kumaran Systems Pvt. Ltd.
Sep 2023 - Feb 2026
Designed and developed a secure banking application front-end using React.js and TypeScript, delivering responsive UI for 50K+ daily transactions with role-based dashboards and real-time payment updates for 100+ concurrent users. Implemented JWT-based authentication flows in React — token storage, refresh logic, and protected route guards — ensuring only authorized users could access sensitive financial operations. Built a custom React middleware layer with centralized error boundaries, global exception handling, and structured notifications, reducing unhandled UI exceptions by 87% and enabling sub-minute incident diagnosis. Optimized performance using React.memo, useMemo, and useCallback — eliminating redundant re-renders and sustaining smooth UI responsiveness across 3x data volume growth. Developed dynamic report generation UI processing 500K+ monthly transactions with compliance downloads in under 2 minutes (vs. 45-minute manual process) and real-time audit trail visualization. Managed Azure DevOps CI/CD pipeline with Jest/RTL automated testing — cutting deploy time from 30 min to 8 min, 99.8% success rate, and 10+ daily releases. Built RBAC-driven UI with 8 distinct roles, dynamic permission-based rendering, and ABAC using React Context API — passed security compliance audit with zero findings.
