أريد نصائح تقنية من مطور ويب خبير لاختيار تقنيات تناسب هذا التطبيق من أجل الأمان و سرعة تحميل الصفحات

أرسل لي مبرمج عرض لتنفيذ التطبيق باستخدام next.js - supbase
هذا خيار سريع ولكني أخشى صعوبة التوسع أو الانتقال الى تقنيات أفضل في المستقبل
أتمنى ارى رد في أفرب وقت 

بحثت في بعض الفيديوهات والمقالات واستخلصت هذه الادوات ولكن اريد من خبير ترجيح الانسب لي في البداية

Next.js - Tailwind -
Nest.js - RESTful APIs -
chat-notifications: Socket.io
Primary Database: PostgreSQL
Secondary Database (for cache): Redis
PWA Tools: Workbox for service workers, Web App Manifest, and Lighthouse for performance auditing Authentication and Authorization:
- JWT for secure user authentication with tokens stored in HTTP-only cookies to prevent XSS.
- Implement OAuth for third-party login options (Google, Facebook, telegram)
- Role-based access control (RBAC) for different types of users (buyers, sellers, admins).

Data Encryption:

- HTTPS and enforcing SSL/TLS
- AES-256 encryption for storing sensitive information like payment methods.
bcrypt for securely hashing passwords.
Protection Against Common Vulnerabilities:
- Implement Content Security Policy (CSP) to mitigate XSS.
- Use input validation and sanitization to prevent SQL injection and other injection attacks.

- **Input Validation**: Protect the system from SQL injection and cross-site scripting (XSS) by sanitizing user inputs and using ORM libraries like Sequelize or TypeORM with PostgreSQL.

- Implement rate limiting and IP blocking to prevent abuse (DDoS attacks, brute force).

Secure User Data Handling:

- Ensure user personal data (e.g., ID cards, email) is encrypted before storage.

- Implement 2FA for sensitive actions like payment method changes or withdrawal requests.

Deployment and Scalability

- digitalocean - Docker - Kubernetes

- CDN: Cloudflare for static assets (images, JavaScript, CSS) and DDoS protection.

- CI/CD: GitHub
