• User Management Platform: I developed a React dashboard to display information about users on a platform. The application was integrated with an API that I built in Node.js, responsible for authenticating users and managing their data. Additionally, I integrated Firebase for authentication and data storage, ensuring a secure and efficient solution for user management. This project was essential in optimizing the information flow, improving data management for the team;• Automotive Inspection System: As the full stack lead of the project, I developed a complete solution to manage the inspection of cars and parts. On the front end, I used Next.js with Tailwind CSS to build a robust interface where users could create, delete, and list data for cars, parts, and inspections. The vehicle section had an integration with Unity for 3D visualization. The API, built in Node.js, not only powered the website but also provided data for an application that visualized the vehicles in virtual reality. The project included the creation of a custom API architecture and the configuration of a MySQL database;• API for Cryptocurrency Game: I developed an API for a cryptocurrency game where it was necessary to manage users' banking information and process cryptocurrency transactions. In this project, I built an API in Node.js that connected to digital wallets via Metamask and integrated with the Klever blockchain;• Virtual Land Purchase Platform: I was responsible for developing an interactive platform for purchasing virtual land in a cryptocurrency game. Using Next.js on the front end and integrating with Mapbox to render a custom interactive map, users could view and purchase land parcels. The platform was also integrated with Metamask to facilitate transactions.

• Tanya Be'al Peh App: I completely developed an educational app for teaching Hebrew aimed at Jewish children, using React Native for the front-end with Styled Components, Node.js for the API, and MySQL as the database. The app allows users to access chapters divided into units, where phrases can be heard through audio to facilitate memorization. It also includes an interactive "Fill in the Blank" game, where users complete sentences by choosing the correct word from the options. The system features resources such as missions, streaks of consecutive days, a leaderboard, and automated email sending for password recovery and registration confirmation, offering a complete learning experience;• Features and Maintenance on Websites: I developed customized graphs, including pie charts and an interactive graph that displayed the map of the United States, where each state showed specific data. For creating these graphs, I used the D3.js library, ensuring dynamic information display according to the provided design. Additionally, I was responsible for ensuring the website's responsiveness, providing a smooth user experience across different devices, and resolving critical bugs, thereby improving the overall performance of the platform.
