Custom Development

Custom Development

Custom software development means building applications tailored to your business instead of forcing it into off-the-shelf tools — and for Australian companies we deliver it on AEST overlap with code in your own AWS Sydney account. Custom software is the right answer when off-the-shelf SaaS doesn't fit the business model. Typically that's one of three reasons. The workflow is non-standard — regulated supply chains, multi-region compliance, offline-first field operations. The integration surface is unusually deep — broker APIs, ERP cores, custom hardware. Or the data model is genuinely proprietary. Where SaaS does fit, we say so. Where it doesn't, we build.

Our default stack. TypeScript across the full stack (Next.js or React on the front-end, Node.js with NestJS or Express on the back-end). Python for data-heavy workloads (FastAPI for services, pandas or Polars for transforms, scikit-learn or PyTorch for ML). Java with Spring Boot where the customer ecosystem requires it. Persistence: PostgreSQL by default, MongoDB for document-shaped data, Redis for caching and queue back-ends. Cloud: AWS by default (Sydney for AU customers), with Azure or GCP where customer constraints require.

Engagements shipped under this stack include a portfolio analytics platform for TR Capital, an offline-first field-data PWA for a US-based sustainability leader, an EUDR commodity-traceability system, and a community-engagement platform for GDi Partners. Each had different failure modes. Different right answers on caching strategy, sync model, audit-trail design, regulatory boundary. The engineering decisions were made against those specifics — not a template.

Built for Australian businesses

Custom software for Australian businesses comes with three constraints that generic offshore vendors aren't always set up for: Australian working hours, Australian-jurisdiction contracts, and an Australian regulatory posture. We've built the engagement around all three.

Our Melbourne office at 251 Frontier Avenue, Aintree is the local point of contact for discovery workshops, sprint demos, and quarterly reviews. Engineering delivery runs from our Delhi NCR centre, where we've been building production software since 2016. Our blended rate is $50–$100 AUD per hour, verified on our Clutch profile.

Daily AEST/AEDT overlap is 4 to 6 hours. Standups, sprint reviews, and ad-hoc calls are scheduled during your working day. By default, your application sits in AWS Sydney (ap-southeast-2). AWS Melbourne (ap-southeast-4) is available for Victorian government workloads and sovereignty-sensitive cases. Either way, the data-residency commitment is in writing in your MSA.

Compliance and data governance

Our Australian engagements meet local regulatory requirements in writing, not just in marketing copy.

Personal data is handled in accordance with the Privacy Act 1988 and Australian Privacy Principle 8 (cross-border disclosure). The 2024 reforms to APP 8 strengthened accountability obligations for disclosures to overseas recipients; our data-handling agreements reflect the current requirements.

Infrastructure follows the ACSC Essential Eight maturity model (current version: November 2023). For EUDR compliance and other EU-facing operations, GDPRrequirements apply alongside the AU regime — the two aren't always compatible, and the trade-offs get discussed before we sign.

User-facing interfaces target WCAG 2.1 AA. Application security follows the OWASP Top 10. Cloud architectures align with the AWS Well-Architected Framework.

We don't claim certifications we don't hold. If a specific certification (ISO 27001, SOC 2, IRAP) is a hard requirement for your engagement, ask us — we'll be honest about whether we have it, can get it, or aren't a fit for this engagement.

Custom development for Australian businesses — FAQ

What does custom software development cost in Australia?

Our minimum project is $25,000 USD. Most engagements sit between $50,000 and $250,000 over 3 to 6 months. Our blended hourly rate is $50–$100 AUD, which covers a typical squad mix — an architect or senior engineer at the high end, mid-level engineers in the middle, and a QA or junior engineer at the lower end. It includes project management, code review, deployment, and standard tooling. It doesn't include third-party SaaS subscriptions, cloud bills, or specialist consulting hours (security audit, penetration testing, legal review) — those get quoted separately.

For comparison, local Melbourne agencies typically charge $150–$300/hr AUD for senior engineers; pure-offshore with no AU coordination runs $30–$80/hr but loses the AEST overlap and AU contracting benefit.

Do you sign Australian-jurisdiction NDAs and IP agreements?

Yes. Australian-jurisdiction NDAs, MSAs, and SOWs are our default for AU clients. IP ownership and any residual rights are spelled out in each SOW — bring your requirements to scoping and we'll structure the agreement around them.

Can you guarantee AU data residency?

Yes, in writing in your MSA. AWS Sydney (ap-southeast-2) is our default. AWS Melbourne (ap-southeast-4) is available for Victorian government workloads or sovereignty-sensitive cases. Azure Australia East is available where the engagement calls for Microsoft tooling. We do not route data through other regions silently, and we don't use offshore-hosted shadow infrastructure.

How does Brainstack compare with an in-house Melbourne hire?

An in-house Melbourne engineer carries the full loaded cost — salary, superannuation, tooling, plus the recruitment cycle and the onboarding amortisation. Our $50–$100/hr AUD blended rate (verified on our Clutch profile) typically sits below the equivalent fully-loaded hourly cost of a senior in-house hire, and includes the project-management and review overhead an individual hire doesn't carry alone. The specific numbers depend on the seniority of the role and your loaded-cost assumptions — ask us during scoping and we'll run the comparison against your actual hiring band.

The honest trade-off is co-location. If your engagement specifically benefits from a Melbourne engineer in your office every day, the in-house hire is the right call.
