Enterprise healthcare applications focusing on pharmacy benefits management for millions of patients. As a Front-End Developer at Accenture, I was responsible for comprehensive UI refactoring of legacy systems, implementing modern React patterns, establishing robust testing practices, and ensuring HIPAA compliance across all user interactions.
2021
Accredo & Express Scripts healthcare applications were built on legacy class-based React components with outdated patterns, low test coverage, and technical debt that was impacting development velocity and user experience for millions of patients.
Lead comprehensive UI refactoring of critical healthcare applications while maintaining zero downtime, ensuring HIPAA compliance, and migrating to modern React architecture with functional components, hooks, and Context API.
Systematically refactored legacy class-based components to functional components with React Hooks, created 20+ custom hooks for reusable business logic and API integration, built a custom UI component library with 40+ accessible components using React and Context API, developed comprehensive unit test suites with Jest achieving 85%+ coverage, integrated ESLint validation pipeline using Gulp, implemented asynchronous API integration with error handling and retry logic, utilized LaunchDarkly for feature flags, and ensured WCAG 2.1 AA accessibility compliance.
Improved code maintainability by 60%, achieved 85%+ test coverage reducing regression bugs by 45%, reduced technical debt by 70%, enhanced user experience for healthcare professionals, improved application performance by 30%, and successfully delivered 10+ modules within Agile sprint deadlines.
The migration from legacy state management to Context API had to be done without disrupting critical healthcare workflows that process millions of patient records daily, while also ensuring HIPAA compliance in all UI interactions.
Execute a seamless migration strategy that maintains existing functionality, ensures HIPAA compliance with data masking and secure forms, and implements accessibility standards without impacting production workflows.
Created a phased migration plan with feature flags, implemented Context API alongside existing state management for gradual transition, added HIPAA-compliant data masking for patient information, ensured secure form handling for sensitive healthcare data, implemented WCAG 2.1 AA accessibility standards, conducted thorough testing at each migration phase, and maintained comprehensive documentation.
Completed migration with zero downtime, maintained full HIPAA compliance, achieved accessibility standards for healthcare compliance, eliminated legacy state management dependencies, and improved application reliability with modern patterns.
