A look at what I build.
A few recent projects — tap any one to see it live.
A simple, honest process.
No jargon, no run-around. Here's exactly what working together looks like, from hello to launch and beyond.
- 01
Discovery call
We jump on a free, no-pressure call. You tell me what you're trying to do, I ask the right questions, and we work out if it's a good fit.
- 02
Plan & proposal
I map out exactly what I'll build, how long it'll take and what it'll cost. Clear scope, fixed expectations, no surprises.
- 03
Design & build
I design and develop in the open, sharing progress as I go so you're never left wondering. You see it take shape, week by week.
- 04
Launch & support
We ship it. Then I stick around — to fix, improve and grow it with you. You've got a developer on call, not a one-off invoice.
Hi, I'm Jay.
Jay Griggs
Software engineer · Riverland, South Australia
I live on a small farm in the Riverland of South Australia with my wife and our two kids. It's a good life — and the same care that goes into looking after a patch of land is what I bring to every project I take on.
I trained as a software engineer six years ago and, honestly, I love it. I love untangling a tricky problem, shaping something from scratch, and that moment a client sees their idea working for the first time. Building software isn't just my job — it's the thing I'd be doing anyway.
When you work with me, you're not handed off to a junior or lost in a queue. You get a senior engineer who listens, explains things in plain English, and treats your project like it's my own.

One developer. Fully invested.
Big agencies have layers. I have focus. Here's what that means for your project.
You talk to the maker
No account managers, no telephone game. The person you brief is the person writing the code.
Senior-level craft
Clean, maintainable, well-tested work — the kind you won't have to pay someone else to untangle later.
Plain English, always
I'll explain the what and the why without burying you in jargon. You'll always know where things stand.
Fixed scope, no surprises
Clear quotes and clear timelines agreed up front. You know what you're getting and what it costs.
Fast where it counts
Sites and apps engineered to be quick — for your users and for search engines. Performance isn't an afterthought.
Here for the long run
Launch is the start, not the end. I stick around to support, maintain and grow what we build together.
What people say.
A few words from the people I've had the pleasure of building for.
I came to Jay with a rough idea and a tight deadline. He turned it into a working web app faster than I thought possible, and explained every step in language I actually understood. He genuinely cared about getting it right.
Priya Sharma
Founder, VyroolAI
Our old website did nothing for us. The one Jay built has us booked out — we're getting enquiries every week from people who found us online. Easily the best money we've spent on the business.
Mark Tobin
Owner, Riverland Cleaning
Jay built us an online booking system that's taken a mountain of phone calls off our plate. It just works, and on the rare occasion we need something tweaked he's straight onto it.

Working with me is a safe bet.
Handing your project to someone takes trust. Here's what I promise in return — in plain English, no fine print.
- 01
No lock-in. Ever.
You own the code, the accounts and the IP — all of it. If we ever part ways, you walk away with everything, no hostage situations.
- 02
Honest advice, always.
If the smart move is a cheaper option, a different tool, or not building at all, I'll tell you — even when it costs me the job.
- 03
We get it right together.
I don't disappear at launch. If something's not working the way we agreed, I'll stay on it until it does. That's the deal.
Good to know.
Still wondering about something? The quickest way to get an answer is to book a call.
It's a free, relaxed 20–30 minute chat. You tell me about your idea or problem, I ask questions to understand it properly, and I give you honest input on the best way forward — whether or not we end up working together.
It depends on what you need, so I quote each project individually after we've talked. What I can promise is a clear, fixed proposal up front — you'll know the cost and timeline before any work begins, with no surprise invoices.
Absolutely. I'm based in the Riverland but work with clients all over Australia and beyond. Most of the process happens over video calls and email, so location is rarely an issue.
That's completely normal, and it's exactly what the discovery call is for. Bring the problem, not the spec — part of my job is helping you figure out the right solution.
Yes. Launch is just the beginning. I offer ongoing support and maintenance so your software keeps running smoothly and can grow as your needs change.
I pick the right tool for the job, but I lean on modern, reliable, well-supported technology — fast web stacks deployed on platforms like Vercel, and native Swift for iOS. The goal is software that's quick today and easy to maintain tomorrow.
Worth a read.
