Developed core trading features and internationalization for the marijustechin/cryptotradingsimulator repository, delivering a full-stack spot trading workflow with real-time data handling and robust backend services. Established a cryptocurrency database schema and implemented backend services in Node.js and TypeScript, including error handling and asset management. On the frontend, set up a Redux-powered portfolio UI with live price updates and toast notifications, enhancing user experience and reliability. Integrated end-to-end internationalization using React and backend middleware, enabling multilingual support across the platform. Addressed asset balance integrity and order processing bugs, and improved code maintainability by removing unnecessary console logs and resolving merge conflicts.
