Over three months, Marijus Smiginas developed the cryptotradingsimulator repository, establishing a robust foundation for a cryptocurrency trading simulator. He set up the project’s scaffolding with React and Node.js, enabling parallel frontend and backend development. Marijus implemented internationalization using react-i18next, supporting English and Lithuanian interfaces with persistent language preferences. He enhanced development and production readiness by configuring WebSocket support for local development, tightening CORS policies, and introducing environment-based API endpoints. Through TypeScript and Redux, he refactored UI components such as the user balance chart for clarity and maintainability, resulting in a secure, demo-ready codebase prepared for future expansion.

Feb 1, 2025February 2025: Laid the foundation for the Crypto Trading Simulator project with full scaffolding. Implemented configuration/files, a README with overview and planned features, and basic client-side routing with a placeholder home page; started server-side structure with empty backend files to enable parallel frontend/backend development. This groundwork enables rapid feature delivery and clearer roadmap execution.
