I build backend systems that go live and stay live.

A real-time AI chat product, taken to release.

An AI companion app where users hold live, persona-driven conversations with distinct virtual characters. I handled the engineering across the stack and ran the full Apple App Store release.

• Real-time AI conversations with text & voice messaging
• Multiple AI personas, each with its own profile and personality
• Credits & subscription system (weekly / monthly / annual)
• In-chat image messaging and profile media
• React Native client + REST API backend + LLM integration
• End-to-end App Store submission, review and ongoing releases

An AI agent that makes and answers real phone calls.

A real-time voice system that can dial any phone number on command and hold a spoken conversation, or pick up an incoming call and talk to the caller — driven by a selectable AI model with natural, low-latency speech.

• Outbound: dials any phone number and starts a live AI conversation
• Inbound: answers incoming calls and talks with the caller in real time
• Pluggable AI models — choose which model the agent speaks as
• Natural, low-latency speech synthesised with ElevenLabs
• Telephony, call routing and media streaming handled via Twilio
• Node.js + Python services orchestrating the real-time voice pipeline
