I build scalable SaaS platforms, backend systems, and the architecture that holds them together, from payments and subscriptions to the cloud infrastructure underneath.
About
A full-stack developer with a decade spent shipping production web applications across marketplace, SaaS, and fitness industries, leading backend architecture and the engineering standards teams build on.
I specialize in Laravel and PHP on the backend while working across the stack with Vue.js. I've led backend development for platforms used by thousands: designing APIs and database architecture, building integrations with payment platforms and third-party services, and establishing engineering patterns for development teams.
Beyond the code, I contribute to technical planning, code reviews and system optimization, and mentor other developers. Most of that work has been remote, with teams across Australia, Singapore, and the Philippines.
