Real ventures. Real systems. Scroll through them like a reel.

No clicking required — each venture unfolds as you scroll, with its stack, role, and systems in view. Pause on any one for a deeper dive.

How I build · scroll through the loop

A founder-operator loop, not a generic design process.

Six steps that repeat across every venture. Keep scrolling — they advance by themselves.

Step 01

Identify the real problem

Before any code, I try to find where the friction actually lives — trust, logistics, UX, ops — and decide what's worth building vs. working around.

From scripting on Roblox to operating real ventures.

The work has evolved — but the thread through all of it is building systems that actually run.

Roblox development & scripting

Started building on Roblox — Lua, game systems, and the kind of small-scope engineering work that teaches you to debug properly.

About

Year 12.
Operating real ventures.

I'm 17, based in Sydney, and in Year 12 — but most of my day-to-day looks more like running a small stack of digital ventures than a school schedule.

I build across software, operations, and systems design: shipping SaaS products, payment flows, analytics dashboards, Discord-integrated operations, and platform-backed systems on Roblox. The common thread is infrastructure — not the hype kind, the kind that actually runs.

I care about the boring parts: webhooks that don't drop, admin surfaces that make ops safe, trust signals that actually reduce fraud, and brand execution that doesn't look like everyone else's template. That's what turns a side project into something you can operate.
