Learn by doing. Prove it by shipping.
I am Preston. I work at the intersection of product management, digital marketing and founder-side building. In 2026 I designed, built and shipped eight AI-powered apps, run an SEO + AI-search agency and co-run a table tennis academy. This site is the proof.
Three pillars, one foundation.
Product, build and business are the three things I do. My core principles are the foundation they all stand on.
Product Management
Digital Product Manager at an app agency, client-facing across concurrent A$60k to A$200k+ builds: value propositions, roadmaps, prioritisation and expectation management, with two juniors and two interns mentored along the way. Before that: PM internships at Telstra and SQL VIEW, and consulting projects with EY.
Creative Building
Eight AI-powered apps designed, built and shipped in 2026: assistants with real-time voice, SEO tooling used on real clients, offline-first PWAs. Built solo with an AI-assisted workflow I designed, and a lessons log that keeps every project compounding.
Business Ownership
Co-founded a table tennis academy and took it from rough months to profitable in year one. Now running PTK Digital Labs, an SEO and automation agency where my own tools produce the client deliverables.
