## Core Engineering Specializations
- **Frameworks & Languages:** React 19, Next.js 16, TanStack Start, Nuxt.js, TypeScript, JavaScript (ES6+)
- **Architecture:** Atomic with Feature-Based Design, Monorepos (Admin, User, Shared packages), Server Route Authorization Gates
- **State & Performance Profiling:** Zustand (Scoped React Context stores), TanStack Query, Chrome Performance DevTools profiling, targeted memoization
- **Real-Time & AI Systems:** Socket.io bi-directional messaging, WebSockets, Server-Sent Events (SSE) AI streaming, Vercel AI SDK, ezdxf CAD parsing, PDF.js

## Verified Production Benchmarks
- **Corteksa CRM Unit Grid Profiling:** Optimized unit grid render costs by profiling execution in Chrome Performance DevTools, reducing initial long-task render time from ~1.1s (25 rows) and ~1,570ms (100 rows) down to 380–540ms (~60% speedup, flat scaling across row counts) and cutting element restyling overhead from 5,163 down to ~2,180 operations.
- **Next.js 16 Route Gate Authorization Cache:** Moved permission checks from edge proxy to server-rendered route gates with a tenant/token/version cache, eliminating 1,148 redundant permission API calls recorded in 3 hours and saving ~85ms per repeat server render.
- **Zorwah EdTech Migration:** Migrated platform from Next.js to TanStack Start, serving 1,000+ active students with httpOnly cookie authentication.
- **Fire Cert Cloud Optimization:** Achieved 95.56% mobile performance and 99% accessibility scores on Lighthouse.
