I'm a senior full-stack engineer and solutions architect with 20+ years building production software — and these days I focus on where that experience meets practical AI. I design and ship SaaS applications and automations end to end: scalable databases and REST APIs, modern web front ends (Next.js, React, TypeScript, Node), and cloud deployment on AWS. My particular strength is integrating AI into real products — wiring third-party AI/LLM APIs like Claude into production systems with tool use and agentic patterns, so the AI actually does useful work for real users rather than sitting in a demo. As one recent example, I built an agentic pipeline that takes a supplier's photo over WhatsApp, uses AI to generate multi-channel content, and routes it back for a human to approve before anything publishes. I've delivered for organisations including Telstra, NAB, Govt across banking, payments, telecommunications and retail, so I bring enterprise-grade thinking on scalability, security and maintainability to smaller, faster builds. I own technical direction, estimate honestly, and I can explain a technical recommendation to a non-technical founder or CFO without losing the room. I work well independently and fully remotely. If you're building a product — especially one with an AI or integration angle — and want someone senior who can architect it, build it, and hand over something others can maintain, let's talk.
