What's included

  • App Security Features for AI-Generated for your application

    - Authentication & Access Control – use OAuth2/MFA, role-based access, and secure session handling. - Data Protection – encrypt data in transit and at rest, manage secrets securely, and apply tenant isolation. - App & API Security – enforce HTTPS, input validation, rate-limiting, CSRF/XSS protections, and strict security headers. - AI/LLM Safeguards – filter inputs/outputs for prompt injection, prevent data leakage, enforce tool allowlists, and redact sensitive info. - Monitoring & Response – centralize logs, detect anomalies, and set up clear incident response procedures.

  • Advanced Caching & Performance Optimization

    Boost app speed and scalability with in-memory caching (Redis/Memcached), CDN edge caching, and smart database query caching. Use lazy loading, request batching, connection pooling, and asset optimization to reduce latency, cut server load, and deliver a smoother user experience under heavy traffic.

  • User Testing, Version Control, Module Testing & Code Review

    Ensure software quality and reliability by validating features with real users, managing code changes through version control, testing modules in isolation to catch bugs early, and conducting peer code reviews to improve security, maintainability, and best practice compliance.

Vincent went above and beyond! He fixed my issue quickly and was able to provide a detailed explanation as to what he did to solve it. Can't thank him enough :)

Vincent is amazing. He went above and beyond fixing this problem for me and even took an extra hour and a half to walk me through everything he did and how to prevent this issue in the future. LOVE working with this guy.
