Developed and optimized a scalable Redux store, managing global state across multiple application modules using Redux Toolkit, RTK Query, useSelector, and useDispatch for efficient state synchronization. Implemented a hybrid state management approach, using Redux Toolkit for global state (e.g., authentication, user preferences, notifications) and useState/useReducer for local UI state (e.g., modal toggles, form inputs, data filters). Built dynamic, interactive UI components using PrimeReact, ShadCn, Daisy UI, and Tailwind CSS, ensuring enterprise SaaS UI consistency, accessibility, and responsiveness across multiple devices. Utilized functional components and React Hooks (useState, useEffect, useReducer, useMemo, useRef, useCallback) to build scalable, reusable, and high-performance UI components. Optimized API interactions by handling CORS (Cross-Origin Resource Sharing) policies, securing API requests, and implementing error-handling mechanisms for smooth API consumption. Implemented complex form validation workflows using React Hook Form (control, register, handleSubmit) with Yup, reducing unnecessary re-renders and improving form submission efficiency. Enhanced application performance using server-side rendering (SSR), static site generation (SSG), lazy loading, and dynamic imports, reducing First Contentful Paint (FCP) by 40%. Developed a structured and scalable routing system in Next.js, leveraging dynamic routes, nested layouts, middleware, and API routes to optimize navigation and user experience. Implemented advanced authentication and session management using JWT, OAuth, and NextAuth, improving security and access control for enterprise SaaS users. Developed enterprise-grade SaaS dashboards and reports using Power BI, integrating real-time analytics with SQL Server and RESTful APIs, allowing business users to gain critical insights. Designed a structured API workflow using Postman, automating API testing, request chaining, and dynamic variable handling, reducing API-related defects by 30%. Built reusable, highly configurable UI components with PrimeReact, leveraging DataTable, Dialog, Toast, Dropdown, and TabView components for a seamless user experience. Implemented Next.js middleware and API routes to handle authentication, request validation, and API security policies, reducing backend load by offloading logic to the edge. Led frontend architecture discussions and code reviews, mentoring junior developers on state management, performance optimization, and UI/UX best practices, improving team efficiency. Software Engineer Power China Gansu Energy | Remote - May 2018 Aug 2021 Led Agile and Waterfall SDLC projects, driving a 18% increase in overall project efficiency by optimizing development cycles, streamlining processes, and addressing bottlenecks in project workflows. Coordinated efforts among cross-functional teams using Jira and Microsoft Project, reducing project delays by 22% and enhancing overall timeline management and communication. Spearheaded debugging and optimization initiatives, improving system performance by 28% and significantly reducing application response times through methodical code refactoring and system fine-tuning. Developed and optimized frontend solutions using Java, JavaScript, and React, enhancing user engagement by 10% through dynamic, responsive UI components and improving overall usability. Leveraged advanced UI libraries and frameworks such as Primereact, Radix UI, and Tailwind to create highly efficient, lightweight, and visually appealing interfaces, decreasing load times by 20%. Architected and maintained robust RESTful API integrations, improving system stability and reducing server-side communication errors by 25% by introducing rigorous testing, error handling, and validation procedures. Managed AWS infrastructure (EC2, ELB, IAM, CloudFormation), achieving a remarkable 99% uptime for mission-critical applications and ensuring high availability and reliability across environments. Worked closely with backend teams to enhance API performance, resulting in faster data processing and efficient retrieval of resources, supporting better user experiences and faster response times. Championed microservices architecture in backend systems, improving scalability, maintainability, and overall system performance by decoupling services and enabling independent deployments. Implemented and fine-tuned SQL queries, optimized database structures, and ensured data integrity to support high-load environments and improve application responsiveness. Contributed to developing unit and integration tests, ensuring high-quality code and reducing the occurrence of bugs in production. Utilized Nagios for proactive system health monitoring, maintaining 98% uptime and ensuring smooth operation of all production applications by detecting issues before they impacted users.
