A small studio that ships serious software
MrjnIT is a web app, cloud and AI development studio based in Australia. We design and build modern websites, custom web applications, developer tooling, scalable cloud infrastructure and intelligent automation for businesses that want software done properly.
Built by engineers who care about the details
MrjnIT started as an AI first technology company, building chatbots, document pipelines and automation platforms for growing businesses. Along the way, the same clients kept asking for the things around the AI: a website that looked as good as the product, a dashboard their team could actually use, an API that would not fall over, and tools that made their developers faster.
So that is what we became: a studio that designs and builds the whole thing. Modern web apps, marketing websites, developer tools, the cloud backbone underneath with Kubernetes, event driven architecture and CI/CD, and AI systems on top, all with the same standards for performance, security and craft.
We stay deliberately small. You talk to the people doing the work, decisions happen quickly, and nothing gets lost between a sales team and a delivery team.

Standards we hold on every single project
These are not optional extras. They are the baseline for anything with our name on it.
Fast by default
Server rendering, image optimisation, code splitting and caching. We target 90+ Lighthouse scores on every launch and measure it.
Secure from day one
Security headers, CSRF protection, rate limiting, encrypted secrets and dependency audits on every project, not just enterprise ones.
Responsive on everything
Designed mobile first and tested on real phones, tablets and desktops so it looks right wherever your customers are.
SEO built in
Semantic markup, structured data, Open Graph images, sitemaps and clean URLs so search engines and social previews just work.
Accessible
Proper contrast, keyboard navigation, focus states and screen reader support. Good for users and good for your reach.
Built to scale
Load balanced, autoscaled and load tested. Whether it is one server or a Kubernetes cluster across three zones, we prove the headroom before launch.
You own the code
Full source in your own repository, documented and deployable by any developer. No lock in, no hidden dependencies on us.
Clear communication and pricing
Weekly demos, a shared board and plain English updates. Fixed quotes for scoped work and transparent rates for support. No surprise invoices.
Support after launch
Monitoring, updates and a real person to call when you need changes. Launch is the start, not the end.
