Fifteen years of shipping web software.

I'm Jared Fraser, a developer in Auckland. I build products end to end and run them once they're live — Rails and Postgres for the parts that have to last, AI for the parts it's genuinely good at.

Shipped

Five products

Products I built and then ran — support, scaling, moderation, the unglamorous half.

Working with me

Four ways that usually starts, whether you need a whole product or one difficult piece of it.

AI-augmented development

Full-stack work with AI in the loop from architecture to deploy. It makes me faster; it doesn't make every decision, and I'll tell you where it isn't earning its place.

AI features and pipelines

Moderation, classification, summarisation, extraction. Pipelines built to survive real traffic, real costs and the inputs nobody planned for.

Rapid prototyping

Idea to a thing you can click by the end of the week, in Python, React or Rails — whichever gets you an answer soonest.

Team enablement

Getting your developers genuinely productive with Claude Code: workflows, CLAUDE.md conventions, and the habits that make the difference.

Tools

Nine, free to use

Small things I got tired of not having. They run entirely in your browser — files you open never leave your machine.
