3. Application Optimization. Optimize applications for scalability, security, and performance, ensuring compliance with secure coding standards.

4. Secure Data Handling

   • Implement input validation and sanitization (e.g., using DOMPurify to prevent XSS attacks).

   • Enforce Content Security Policy (CSP) headers to mitigate injection attacks.

5. API Hardening

   • Apply rate limiting to prevent abuse.

   • Set up CORS restrictions to ensure controlled access.

   • Validate and sanitize inputs (e.g., using express-validator) to prevent SQL Injection (SQLi), NoSQL Injection (NoSQLi), and brute-force attacks.

   • Regularly scan dependencies for vulnerabilities using tools like Snyk.

   • Store sensitive data such as API keys and database credentials securely using environment variables or AWS Secrets Manager.

6. Frontend Development. Design and implement responsive and intuitive user interfaces using React.js.
7. Collaboration & Feature Development. Work closely with designers, product managers, and other engineers to define, develop, and deliver new features.
8. Performance & Scalability. Ensure that applications are optimized to handle high traffic while maintaining high performance.
9. Testing & Debugging. Conduct thorough testing, debug issues, and ensure high-quality deliverables.
10. Code Reviews & Best Practices. Participate in code reviews, share constructive feedback, and promote best coding practices.
11. Continuous Learning. Stay up to date with emerging technologies and industry trends to continuously improve development processes and methodologies.
