Fullstack AI Engineer

Daniel Sarney

Fullstack AI Engineer

I bridge the gap between AI innovation and production delivery. With 10+ years of enterprise engineering experience and a Computer Science specialisation in AI/ML, I integrate AI into existing web applications or build new AI-enabled web products from the ground up.

What I Do

I help businesses implement AI within existing web platforms or deliver complete web applications with AI built in, designed to be secure, high-performance, and production-ready.

Intelligent AI Solutions

Building custom AI agents and automated workflows that move beyond prototypes into production. I deliver intelligent systems designed to generate measurable business outcomes.

Full-Stack Product Engineering

Designing end-to-end web applications, from polished, intuitive user interfaces to the secure, high-performance engines that power your entire business.

Seamless Business Integration

Ensuring new technology and AI features work seamlessly with your existing tools, databases, and APIs. I bridge the gap so new capabilities fit your operational workflows.

Reliable & Scalable Systems

Designing robust, cloud-native solutions built to handle high traffic and rapid growth without sacrificing reliability, security, or performance.
