Kashif I.

I build mobile apps, AI voice agents and the systems behind them, and I've been shipping production software for 14 years. Most clients come to me for one of three things. AI agents and voice agents • AI agents that answer questions, take actions in your tools and hand over to a person when they should • Voice agents that answer and place phone calls • Backed by 5 years of VoIP work (SIP, WebRTC), so call quality, routing and telephony are familiar ground Mobile apps • iOS and Android in Swift, Kotlin, Flutter and React Native • 5 years on VoIP calling and messaging apps for iOS and Android: SIP calling, group chat, media sharing, in-app billing • 3.5 years on a grocery e-commerce platform's native apps, used by three major US retail brands • Bluetooth (BLE) apps that talk to hardware, such as a live force-sensor app built with CoreBluetooth Shopify, payments and backend • Custom Shopify apps and checkout extensions • Real-time shipment tracking across 100+ carriers • Stripe and other payment gateways, in-app purchases • Node.js, Python, PostgreSQL, Firebase and AWS How I work • I tell you what I'd build, and what I wouldn't, before you spend anything • You see working builds early instead of one big reveal at the end • Clean, documented code that another developer can pick up Top Rated on Upwork. Master's in Computer Science (Artificial Intelligence). Tell me what you're building and where it's stuck, and I'll tell you how I'd approach it.
