About

Senior engineer turned AI systems architect.

I'm an AI Solutions Architect & Senior Software Engineer with over 8+ years shipping production mobile and web applications at scale. I built a white-label e-commerce platform serving 1,000+ businesses and 300K monthly end users, delivered 6 production React Native apps for major AU/NZ fashion brands (Glassons, RedRat, Hallensteins), and architected multi-tenant SaaS with PostgreSQL Row Level Security.

I founded ZKidz Dev in 2020 and own end-to-end delivery across 15+ production systems — architecture, API design, CI/CD, App Store release, and post-launch monitoring — for clients in Australia, the US, Canada, and New Zealand. After years of full-stack client delivery, I built an AI workflow around Claude AI: directing agent teams, enforcing TDD, and shipping features 3-5x faster with automated code review on every task.

FAQ

Common questions about working with me, process, and technical depth.

Working With Me

Yes. I take on select freelance and contract projects where I can own meaningful outcomes - usually mobile apps, web platforms, or full-stack SaaS work. I am also open to the right long-term remote role.
The process usually moves through discovery, architecture and planning, iterative development, QA, and launch. Communication stays clear and async-friendly, with regular updates and visible progress.
The strongest fit is React Native mobile apps, React or Next.js web products, and full-stack SaaS systems. I tend to be most valuable on products that need production-quality code, scalable architecture, and end-to-end ownership.
I prefer clear async communication: Slack or Teams for day-to-day work, short Loom or written updates for progress, and weekly sync calls when alignment matters. The goal is visibility without noise.

Technical

My core stack is React Native and Expo for mobile, React and Next.js for web, TypeScript throughout, Node.js or Express for APIs, and Supabase or Firebase-backed services. PostgreSQL, GraphQL, Zustand, TanStack Query, and Tailwind are also common parts of delivery.
Yes. I handle CI/CD with Fastlane, Bitrise, GitHub Actions, EAS, and modern web deployment flows. That includes app store submissions, Vercel or AWS deployments, and database migration workflows.
Absolutely. Existing codebases are a normal part of the work. I usually start with an audit, identify quick wins and structural risks, then make changes incrementally so improvements do not break active delivery.
Yes. Post-launch support can include fixes, performance monitoring, feature iteration, release support, and ongoing retainers depending on the product and how hands-on you want the relationship to stay.
