Avatar Studio, Free-Tier Scale & Database Optimization, Pure Redis Scans & Security Hardening
Introduced Avatar Studio with Prestige Halos and live milestones, alongside comprehensive free-tier scale optimizations: pure Redis <5ms redirects with zero Neon wakeups, database composite foreign-key indexes, N+1 query elimination, Vercel Hobby 2-cron split, Upstash command reduction, request-memoized admin security guards, and resolution of 494 Request Header Too Large / cookie chunking.
494 Request Header Too Large & Token Pruning
Pruned redundant user properties, IP history, and heavy avatar JSON payloads from JWT session tokens to eliminate cookie chunking overflow.
Automated Chunked Cookie Cleanup
Added proactive cleanup of legacy chunked session cookies (.0 through .9) across signout and authentication failure handlers.
Avatar Studio & Prestige Halos
Interactive avatar studio with custom photo optimization, initials monograms, and prestige animated halos (Electric Blue, Neon Emerald, Titanium Outline, Sovereign Crown).
Campaign Milestones & Rewards
Live scan milestone tracker rewarding campaigns with unlockable prestige tiers, rarity classes, and progress metrics.
HugeIcons Library & Icon Picker
Searchable vector icon picker integrated directly into the custom logo generator with real-time SVG canvas rasterization.
Supporter Badges & Milestones
Supporter badge progression celebrating long-term supporters with custom badges and anniversary achievements.
Pure Redis Scans & Scale-to-Zero (<5ms)
Moved scan counts and landing page rendering to Upstash Redis, preventing Neon database wakeups from scan traffic and ensuring full scale-to-zero compute savings.
Database Indexes & Deduplicated Connection Pool
Added foreign-key and composite filter indexes across Users, QRCodes, and Workspaces, and deduplicated Prisma WebSocket pools.
N+1 Bulk Scan Aggregation Elimination
Consolidated batch scan aggregations into a single grouped query, cutting database queries by up to 95% on bulk dashboards.
Vercel Hobby 2-Cron Split
Split background tasks into 2 dedicated daily crons, preserving QStash scan flushes while combining telemetry drain and 30-day tombstone cleanup.
Request-Memoized Admin Authentication Guard
Implemented verifyAdminSession with React.cache and direct primary-key database lookups to instantly enforce demotions, suspensions, and role changes.
Session Tombstoning for Deleted Users
Configured NextAuth JWT and session callbacks to immediately revoke and purge active sessions when an account is deleted or restricted.
Stripe Checkout & Billing Portal Rate Limiting
Enforced sliding-window rate limiters per user identity on Stripe checkout and portal creation endpoints.
Finder-Adaptive Logo Backing Badge
Dynamic corner radius calculations adapting badge roundness seamlessly to match QR finder styles (dots, liquid, rounded, square).
Mobile Profile Hero Layout
Redesigned the mobile identity header to a centered hero showcase and converted milestone action stats into a balanced 2-column mobile grid.
Sleek Circular Arc Loading Spinner
Replaced the jagged segmented loading icon across all buttons and modals with a minimalist 270° smooth circular arc.
Root Layout Script Tag Parity
Replaced manual head scripts with Next.js beforeInteractive Script component, eliminating React 19 client execution console warnings.
Tenure Modal Light Mode Contrast
Eliminated boxed border cards in favor of borderless soft-surface tiles with full light and dark mode parity.
