Remote full-stack development focusing on building modern web applications with Node.js, Express, React.js, and GraphQL. Implemented real-time features with Socket.IO, designed scalable RESTful APIs, and optimized performance for large data volumes using MongoDB. Collaborated with backend engineers, integrated Docker-based deployments, and contributed to system architecture for reliability and scalability.

Developed responsive web apps using HTML, CSS/SASS, JavaScript, TypeScript, and React.js; built reusable UI components and a stable global state management structure using Material UI, React Router DOM, Zustand, and Context API; managed app state with Redux and optimized API calls using Axios, Fetch API, and REST services for faster data retrieval and improved responsiveness. Implemented real-time features with Socket.IO on both client and server sides; leveraged GitHub Actions, Docker, and cloud hosting to automate deployment and ensure system stability, scalability, and reliability. Built a secure file upload system using Multer and Cloudinary, enabling scalable cloud media storage, faster delivery, and reduced server workload.

Developed real-time features with Socket.IO on client and server sides; built a reusable UI component library using Material UI, Zustand, Context API, and React Router; created real-time dashboards with live data updates for faster, data-driven decisions. Implemented back-end with Node.js, Express, and MongoDB; integrated GraphQL APIs; collaborated with backend to optimize data pipelines. Set up CI/CD with GitHub Actions and Docker, implemented secure file uploads with Multer and Cloudinary, and migrated to cloud hosting for scalability.
