The city Holden left. Coming back in code.

Yes, onshore, in regions a procurement desk recognises. Neon and Supabase both offer AWS ap-southeast-2 (Sydney) for Postgres, which is the standard Australian data residency region. Vercel runs compute on the global edge, with an option to pin server functions to Sydney. If you have sensitive obligations (Defence, APP entity, health, finance), we set the stack up to match: Sydney-pinned compute, Sydney database, env secrets in your own accounts, and documented data flow diagrams for your security review. This is real infrastructure inside AWS, not a marketing claim. Many Adelaide buyers work downstream of prime contractors with strict residency rules. The architecture exists to meet them.

No, Studio Slate itself is not IRAP assessed. That is honest. Most small custom builds do not need it. What we do is build your software on top of IRAP-assessed infrastructure (AWS regions with IRAP PROTECTED accreditation, Cloudflare Australia, Vercel on AWS). Your code lives in your GitHub organisation, your Vercel team, your AWS account. The security boundary is your tenancy, which means your primes assess the codebase, not us. If you need a formally accredited build partner from day one, we are not the right fit. If you need a fast, clean build on accredited infrastructure that your internal security team can audit line by line, every commit in Git history, that is exactly what we ship. Three Adelaide defence-adjacent buyers have already asked this question. The answer is the same every time.

Completely. Your GitHub organisation, your Vercel team, your Neon project, your Stripe account, your domain, your environment variables. We are invited in as collaborators for the build and the moment the project ends you revoke our access. There is no proprietary CMS, no hosted platform we control, no runtime only we can service. The codebase is a standard Next.js monorepo any Adelaide dev can open in Cursor or VS Code and understand in an afternoon. For procurement teams: every artefact is traceable in Git, every secret is in your vault, every deploy ships from a pull request that lives in your history forever. You own the audit trail as much as the code.

Next.js on Vercel, PostgreSQL via Neon or Supabase, Stripe for payments, TypeScript end to end, Tailwind for styling, Radix or shadcn for primitives. Auth via Clerk, NextAuth, or a custom JWT implementation depending on requirements. The same architecture Stripe, Linear, Cal.com, Notion, and Loom run in production. We chose it because it gives us typed server actions, edge deployment, preview URLs on every pull request, migrations in version control, and zero vendor lock-in at the framework layer. If you hand the repo to a senior engineer at SAAB Systems or Nova Systems next year, they will recognise every file in the tree.

Every project ends with a handover document and a Loom walkthrough. The document covers the data model, the auth flow, every environment variable and what it does, the deployment pipeline, the test suite, local dev setup, and every third-party integration. The Loom is a 30 to 60 minute screen recording where the founder walks the repo file by file. Your internal dev, a contractor from Lot Fourteen, or the next senior you hire can be productive inside a day. No black box, no tribal knowledge, no retainer hostage. We have done this handover to internal teams where the brief was explicitly that we build it and then disappear, and the code has kept shipping features years later without us on the bill.

Every build includes 30 days of post-launch support at no extra cost. Bugs, small changes, environment issues, questions from your internal team. After that, three options. One, a maintenance retainer from $497 a month covers bug fixes, dependency updates, and small feature additions. Two, your internal dev or an Adelaide contractor takes over because everything is standard and documented. Three, you call us on demand and we quote the specific scope. No lock-in, no 36-month hosting contract, no minimum commitment. The door is unlocked the day we ship.
