I build scalable, production-ready full-stack AI applications. My project, CareerSyncAI, is built with Next.js, PostgreSQL, and Zod. Its AI assistant uses function calling for CRUD operations and scores 93.33% on extraction tasks. I also use Redis and unique request IDs to prevent concurrent double-charges. My 2nd project (Team Task Manager) uses PostgreSQL transactions to prevent orphaned teams. As a dedicated Full Stack AI Developer, I am available immediately to build high-quality web apps for your business. Portfolio: ali-haider-dev.vercel.app | GitHub: github.com/qh8773127-star
