About
The person behind the studio
I'm heyedd — a Sydney-based engineer working across the React / React Native / Node / AWS stack since 2014. I build greenfield products, lead engineering teams, and step into projects that need rescuing. Some of what I've built lives under Past engagements; if you'd like to bring me in for one of your own, the Services page is the place to start.
Services
What I can do for you
Five overlapping practices, picked up and dropped down depending on what an engagement needs.
Tech lead, architecture & fractional CTO
For teams of 2-6 — tech leadership, architecture decisions, code review culture, and fractional-CTO engagements where you need senior shape without a full-time hire.
Website development & hosting
Brochure, content, and marketing sites — Astro / Next.js / static — designed, built, deployed, and hosted end-to-end.
SaaS development (Web application)
React, Next.js, or Astro front-ends with thoughtful UX, sensible accessibility defaults, and the right amount of state.
Mobile app development
React Native and Expo apps for iOS and Android — including white-label codebases that branch into multiple branded apps.
AI & automation
RAG pipelines, LLM integrations, and the unglamorous automation — workflows, scripts, scheduled jobs — that takes routine work off your plate.
Full-stack engineering
Node + TypeScript backends, REST and GraphQL APIs, Postgres / MongoDB, deployed on AWS or your cloud of choice.
Custom technical work
Framework migrations (Gatsby → Next.js → Astro), legacy code rescue, and stuck projects that need an unbiased pair of hands. Plus other bits and pieces that don't fit a standard service line.
Past engagements
A small slice of recent work. Full list at /work.

If you came from Jekyll or Gatsby, you want a git-based CMS
Why a git-based CMS is the natural successor to Jekyll or Gatsby — your content stays as markdown in the repo, the editor just sits on top. Plus what I found running Decap and Sveltia side-by-side.
My first RAG, part 2: I built generation. One endpoint sang. The other lied about people needing the bathroom.
Week two of the RAG project — added /summarize and /answer on top of retrieval. /summarize was the surprise hit. /answer had a polite refusal problem and then a stranger one. Notes from the workbench.
My first RAG
From zero Python service experience and zero RAG knowledge to a working YouTube transcript retrieval pipeline. The mental shifts, the decisions, and the gotchas that surprised me.
