Obsessed with how things work and how problems get solved. Creative idea guy, chronic tinkerer — the kind of person who has to build the thing to really understand it. Every project is another chapter in figuring out who I am. if I don't know it, I'll know it by Friday.

Three chapters, right now.

Each one solves a different problem and demands a different shape of me — software, strategy, brand. Below in roughly the order they went live.

Health Agent — pharma & doctor portals.

I build the user-facing layer for patient-assistance analytics — dashboards where pharma teams visualise, interpret, and export program performance. The first portal went live in March; I'm now mid-way through the doctor-facing portal: registration, prescriber validation, adherence tooling. My first time working inside a regulated software lifecycle, and it's shaped how I build.

  • Contributed to the client-facing pharma dashboard through to its March release
  • Building the doctor portal: auth, registration, prescriber ID validation, adherence flows
  • Exposure to patient adherence, inventory, and logistics workflows
  • Learning the habits of regulated software — versioning, audit trails, accessibility

Arctiq — refrigeration, re-engineered.

Arctiq is rethinking refrigeration for the vaccine cold chain — smarter compression cycles, a lower energy footprint, and fridges that actually behave like medical equipment. Our first operational product, the “black box” (an RFID-retrofitted monitor for clinic fridges), is already revenue-generating. We're now partnered with a professor at Melbourne University to build the next-gen prototype. I own brand and strategy; the current content push and positioning is setting me up for a bigger role here in a few months.

  • Black box (RFID-retrofitted fridge monitor) operational — revenue-generating at clinics
  • Commercialising — pushing the black box into more clinic fridges across the network
  • Next prototype in R&D with Melbourne Uni — smarter compression, sustainable cold chain
  • My seat: brand, positioning, and go-to-market strategy as the product matures

404 — No Limit Found.

Sportswear for the ones who show up when no one's watching. Co-founded on one idea — limits are self-imposed. Built for the early-morning sessions, the reps nobody sees, the decision to keep going when the easy option is to stop. Clean, minimal, intentional — nothing overdone, nothing unnecessary.

  • Built the Shopify storefront end-to-end — custom product config, checkout, CMS
  • Modelled and rendered 3D product assets in Blender for shoots & hero moments
  • Shaped the visual identity, typography and brand voice from scratch
  • A brand built on discipline — sport as routine, identity, ambition, expression

04 / About & history

Commerce degree, developer trajectory.

Studied finance, graduated, went straight into software. The commerce lens is a feature — I read specs like balance sheets and I'm obsessed with what makes something actually ship.
