We're AI experts who ship software 3× faster — inside a controlled framework where AI accelerates the work and humans make every key decision. The result: your problem solved months sooner, at lower cost and with momentum your competitors can't match.
Terminal illustration: AI explores architectures and builds under guardrails; a human signs the key decisions and the release. Result: TrustedCalcs live in production.
Options, prototypes and architectures generated in hours, not weeks.
Architecture, scope, security and spend — decided by a person, on the record.
Implementation at machine speed under guardrails the AI cannot skip.
Reviewed, tested, signed off. Nothing reaches production unseen.
"AI proposes. Humans decide. We use AI to move faster — never to think less."
Our own products go through the same four gates as client work — explored by AI, decided and signed off by a human. Two of them so far:
Free finance calculators, developer tools and unit converters that show their working. Every result includes the formula behind it, and everything runs in your browser — your numbers never leave your device.
Family location tracking with intelligent route monitoring — not just a dot on a map. Route-deviation alerts, unexpected-stop and late-arrival notifications, and one-tap SOS, built privacy-first from day one.
Modern, fast, accessible — built to be maintained, not just launched.
Containerised, GitOps-deployed. Our own products run the same way.
LLM features with guardrails, evals and human sign-off — the framework, applied to your product.
20+ years in finance systems: salary packaging, mortgages, tax and compliance-heavy builds.
Android-first product engineering, with iOS where it counts.
Ageing .NET and beyond, moved to modern platforms without stopping the business.
You describe the problem in plain language. No discovery-workshop theatre — one conversation, straight with the engineer.
You get an honest fixed scope with the four gates written in: what AI does, what a human signs off, and when you'll see working software.
Working software in weeks, demonstrated at every gate. You see progress, not status reports.
Mental Monkey Software is an independent Australian software practice — one Solution Architect / Senior Software Engineer with 30+ years building software, more than 20 of them in finance: salary packaging, mortgages, FinTech and other systems where a wrong number is not an option. There are no account managers and no hand-offs. The person you talk to is the person who designs, builds and ships your system — with AI doing the heavy lifting under supervision.
