Websites, mailing lists & infrastructure · Sydney
A website you own, edit yourself, and never have to babysit.
I’m Joseph Derrick. I build and design websites and the infrastructure behind them: sites that run on your own accounts, mailing lists you actually own, and the weekly jobs you’d rather not do by hand. For bands, artists, small businesses, community groups and larger organisations. No project is too big or too small.
31 live projects, 10 of them for clients.
How I can help
What brings you here?
Pick the one that sounds most like you.
- 01How I’d help →
I’m paying every month for a WordPress, Wix or Squarespace site
Most sites don’t need any of them. Move it, keep editing it, stop paying for it.
- 02How I’d help →
My site is broken, expired, or the person who built it has gone
I can usually get it all back, and put it somewhere it can’t lapse again.
- 03How I’d help →
I want a mailing list I actually own
Your list, your sending account, about a tenth of the price.
- 04How I’d help →
A fiddly job eats part of every week
If you can explain it, I can probably make something to make it easier, or even automate it.
Stories
Real jobs.
What was wrong, what I did, and how it turned out.
The Good Behaviours
A band I love, a mock-up made on spec, and a site that now costs them roughly the price of the domain.
emus — exploratory music sydney
Nine years of Sydney's experimental music gigs, moved off Squarespace without breaking a single old link.
Splinter Orchestra
The subscription lapsed. The site was rebuilt from an archived copy, and now looks after itself.
Safe in Sound
An accessible music program for people with disability, rebuilt so it's accessible to edit too.
Robbie Avenaim
A drummer and installation artist who now updates his own site.
A piano teacher's timetable
Twenty-four students, two campuses, a fifteen-minute walk between them, and a school calendar that never sits still.
BoxDivvy
Every week a food co-op turns a spreadsheet of orders into four sheets of paper that tell volunteers what goes in which box.
The Kyle & Jackie O reports
I built a machine to listen to a breakfast radio show so you didn't have to. It was seven weeks old when the show ended.
My own products
Currawong
Small tools, well kept.
I make Currawong as well: kind, careful software for any business or organisation. Each app does a single job and looks after it properly, and they all share one sign-in. Two of the stories above run their mailing lists on it.

Tell me what you’ve got.
A website, a redesign, hosting that keeps falling over, a mailing list, something you’d rather stop doing by hand. Tell me what you’re trying to do and what’s in the way, and I’ll tell you honestly whether I can help.
Only your name, email and a message are needed. The rest just means a better first reply.
I also run a woodwind & brass repair workshop, so I know the small-business side of the table too. josephderrick.repair ↗
