What we do Our work About SkillsMax.Ai ↗ Let's build →

Built Different.

We engineer production systems. AI is how we build them.

The hardest part of AI isn't the model. It's the environment it has to run in — and the data that feeds it.

Banking. Energy. Healthcare. Finance. Where failure means compliance breaches, failed trades, or missed treatments.

Who we are

The engineering partner for systems that can't fail.

We've been building production technology in regulated industries since 2015. Banking. Energy. Healthcare. Financial markets. APRA. ASX. ADHA.

That work put us inside the systems before AI became the lever worth pulling.

We understood the data and the constraints they operate under. So when we build AI, we build it to survive them.

We build the AI. The infrastructure underneath it. The platforms around it. We stay until it runs.

Services

We engineer AI into real systems. Here's how.

01 · AI Engineering

AI systems, data infrastructure, and AI-accelerated delivery.

We build AI into workflows, pipelines, and platforms that already run under constraint — LLM orchestration, RAG, and ML where it actually holds up in production.

The Work:
  • EnergyAustralia: Figma to production React via multi-LLM pipeline. 6 weeks → 3 min 30 sec
  • OneTwo Finance: ML classification inside live loan approvals. Manual triage eliminated
  • TSLS: NLP chatbot integrated into a government scholarship platform. Multilingual. 24/7.
  • ResetData: AI marketplace with model integration, usage-based billing, automated service provisioning.

02 · Platform Engineering

Production infrastructure in environments that can't fail.

We build and rebuild the systems AI runs inside — banking, trading, healthcare, payments — where compliance and uptime are constraints, not features.

The Work:
  • NAB: loan origination rebuilt on microservices. Contract generation: 2 weeks → 2 hours. 300 staff freed from manual processing.
  • Powerwrap: cloud-based trading platform. 2× CSAT/NPS. Supported their ASX IPO.
  • Montu: full healthtech platform under Schedule 8 compliance. 250,000+ consultations. 20,728% revenue growth.
  • IASAS: API-driven data ingestion replacing legacy file-based architecture for insurance and superannuation regulatory environment.

Engagement model

We don't just show up. We stay until it runs.

Assess and architect

We define the technical reality of your current stack and design the target architecture.

Weeks 1–4 | Output: Technical Spec

Build and deploy

Our engineering teams embed with yours to build the production system.

Months 1–6 | Output: Production Code

Run and evolve

We provide managed operations or hand over a system that is fully documented.

Ongoing | Output: Uptime & Growth

What the first conversation looks like:

"Our first conversation is about your data gravity, your compliance constraints, and your production bottlenecks. We start where the work is hardest."

Still planning?
We've been shipping.

Most organisations have spent two years on AI roadmaps. Workshops. Proof of concepts that looked good in a boardroom and never reached a production system.

We've been building during that same window — AI pipelines at EnergyAustralia, document classification at OneTwo Finance, regulated infrastructure at NAB, Powerwrap, and Montu.

The gap isn't budget. It isn't access to models. It's the engineering depth to build AI that survives contact with a real, regulated system — and the discipline to stay until it runs.

Production is the only proof.
