He builds web platforms, iOS and Android apps, and AI automations, and is currently a Full-Stack Engineer at Callture. He has 4+ years of experience and 50+ delivered projects for clients in Australia, the United States and Pakistan.

Full-stack web applications (Next.js, React, Node.js), cross-platform mobile apps for iOS and Android (React Native, Expo), AI agents, chatbots and voice agents, CRM and business automations (n8n, HubSpot, GoHighLevel, Odoo), and the cloud infrastructure to run them.
