Production Hardening: Security, Speed, and Structure

Stronger authentication defenses, faster database queries, and a more maintainable architecture.

Security Performance Architecture

Arivu is now more secure, faster, and easier to evolve. This update focuses on the invisible infrastructure work that separates a side project from a production-ready product.

We completed a comprehensive hardening pass across three domains: authentication security, database performance, and code architecture. Here’s what changed and why it matters.

Security

Your account is now protected against brute-force password attacks. Repeated failed login attempts trigger a temporary lockout, stopping automated guessing while letting legitimate users recover naturally.

We’ve also hardened authentication flows to prevent account enumeration—attackers can’t probe for valid email addresses by analyzing response patterns.

What this means for you: Your credentials are better protected against common attack patterns. Login remains seamless for normal use.

Other security improvements:

  • Enforced HTTPS with stricter transport security headers
  • Production-only secure cookie settings
  • Bounded resource limits on content fetching to protect against abusive inputs
  • Improved exception logging for faster incident detection

Performance

Dashboard and search now load faster thanks to targeted database optimizations. We added indexes for the most common query patterns—loading your bookmarks, filtering by read status, and fetching AI summaries.

Connection handling is now more efficient with pooled connections and payload compression. The Memory Jogger feature, which surfaces forgotten bookmarks, had its query patterns rewritten to eliminate unnecessary database round-trips.

What this means for you: Faster page loads and snappier search, especially as your bookmark collection grows.

Architecture

We split core services into smaller modules with clear boundaries. Authentication, configuration, database access, and security functions now live in dedicated components rather than a single growing file.

What this means for you: We can ship features faster with fewer bugs. Changes are isolated, tested, and deployed with more confidence.


This work is ongoing. As we prepare for scale, we’ll continue hardening security, optimizing performance, and improving the codebase. The goal: an app you can trust with your knowledge.
