I build AI-native products that ship — from LLM integrations and voice AI systems to scalable full-stack platforms.
Building the future with AI
I'm a Senior Software Engineer with 6+ years building AI-native products and full-stack platforms. I specialise in LLM integration, voice AI systems, and scalable cloud architectures.
I've shipped products used by millions — from HIPAA-compliant mental health platforms to real-time voice AI agents. My work bridges cutting-edge AI research with production engineering discipline.
I thrive at the intersection of product thinking and engineering excellence — turning complex AI capabilities into delightful, reliable user experiences.
