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.
Products I built and then ran — support, scaling, moderation, the unglamorous half.
Content moderation for businesses and communities, run by models instead of a queue of tired humans.
Rails · Postgres moderantai.com →Destiny 2 character builds, collected and made searchable so players can find one that fits how they actually play.
Rails · Postgres · Alpine builders.gg →Tracks what game developers post across social media, so players don't have to watch six accounts to catch an update.
Rails · Postgres devtrackers.gg →Up-to-the-minute tools for Old School RuneScape players, fed by a game economy that moves every few minutes.
Rails · Postgres · Svelte osrsvault.com →A Fortnite companion that read your gameplay back to you. Served millions of players a month at its peak.
Rails · Postgres Acquired 2018Four ways that usually starts, whether you need a whole product or one difficult piece of it.
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.
Moderation, classification, summarisation, extraction. Pipelines built to survive real traffic, real costs and the inputs nobody planned for.
Idea to a thing you can click by the end of the week, in Python, React or Rails — whichever gets you an answer soonest.
Getting your developers genuinely productive with Claude Code: workflows, CLAUDE.md conventions, and the habits that make the difference.
Small things I got tired of not having. They run entirely in your browser — files you open never leave your machine.
Tell me what you're building.
