Rapid Development with AI Support
Creating the Frontend with v0.dev and cursor.com
The frontend was efficiently developed with the assistance of artificial intelligence. v0.dev was used to generate basic graphical interfaces, allowing rapid iteration of layouts and components, significantly reducing the time usually spent on UI design. The use of v0.dev allowed me to quickly implement and modify components that would have otherwise required more extensive manual coding and testing.
Cursor.com further facilitated development through the use of advanced models, such as Claude and GPT, which helped optimize the frontend and write the backend. AI provided code suggestions, optimized functionality, and resolved issues that would have taken hours of manual debugging. By integrating these AI tools, the development process became significantly smoother, allowing for rapid prototyping and continuous improvement without getting bogged down by minor issues.
Technological Integration
Although the tech stack consists of various tools, their integration was seamless and harmonious, creating a cohesive and efficient workflow:
- Deployment with Next.js on Vercel: Deployment was facilitated by the native integration with Vercel, which fully supports API Routes, ensuring synergy with Supabase. The deployment process was intuitive and enabled continuous deployment, meaning every change could be tested live within minutes.
- Database Management with Drizzle ORM: Drizzle proved to be a lightweight and effective ORM, simplifying CRUD operations without introducing unnecessary complexity. It helped maintain clean and maintainable code, reducing the learning curve for developers unfamiliar with more complex ORM systems.
- UI Components with Shadcn: To avoid building graphical components from scratch, I employed Shadcn, ensuring consistency in design and saving time. Shadcn’s pre-designed components made it easy to implement a professional-looking UI that was both responsive and user-friendly, allowing more focus on the core functionalities of the application.
The Fundamental Role of AI in the Application
AI not only acted as a development support but represents the core of ExaminatorAI. The application leverages AI to provide a sophisticated and personalized experience for users, fundamentally changing how students prepare for exams.
