🔐 Environment & Security
Sensitive data like the Google Gemini API key is stored securely using .env files and environment variables. This ensures credentials are never exposed in the source code, following best practices for secure development.
⚔️ Challenges Faced & Solutions
1. Model Switching & Latency Tracking
Challenge: Handling multiple AI models with varying response times
Solution: Built a dynamic model registry and response timer to optimize performance and user experience.
2. Code Review Categorization
Challenge: Parsing AI feedback into severity levels
Solution: Developed a custom parser that tags feedback based on context and keywords, improving prioritization.
3. Animated UI Performance
Challenge: Maintaining smooth animations without lag
Solution: Leveraged GPU-accelerated CSS transitions and minimized DOM updates.
4. Mobile Responsiveness
Challenge: Ensuring consistent UX across devices
Solution: Used Tailwind’s responsive utilities and tested across breakpoints.
5. Secure API Integration
Challenge: Protecting sensitive keys and endpoints
Solution: Used server-side API routing and environment variables to keep credentials hidden.
