Software
built with intent.
I'm Paulo Cauhi — a solo builder running Nuno. I design and ship web apps at AI-native speed, and I implement AI automation that takes real work off your team — weeks instead of quarters, taste instead of meetings.
Five practices.
One person.
I work across five overlapping disciplines — because real products rarely fit neatly into one. Engage on a single track, or the whole stack.
Idea → MVP
From back-of-napkin to live product in weeks, not quarters. I plan the architecture, direct the build with AI, review every output, and ship a real working version of your idea — faster than any traditional dev shop, at a fraction of the cost.
- Full-stack web apps with auth, database, payments
- Real product, not a prototype
- Deployed, monitored, ready for users
- Typical timeline: 3–6 weeks
AI Features & Integrations
Add intelligence to the product you ship. I design and implement LLM features — assistants, summarization, classification, search — right inside your app, using the same AI tools I build with every day.
- Custom LLM features in your app
- RAG, embeddings & semantic search
- In-product copilots & assistants
- Vendor-agnostic — Claude, GPT, or open models
AI Automation & Agents
Hand the busywork to AI that actually does the job. I build custom agents and automations that take real, multi-step tasks off your plate — triaging the inbox, moving data between tools, running ops — plus a personal AI assistant that runs your day like a tireless secretary. Not chatbots. Workers.
- Custom agents that complete multi-step tasks
- Personal AI assistant — email, calendar, scheduling
- Support, sales & operations automation
- AI audit & roadmap — where AI pays off first
Marketing & Landing Sites
High-craft marketing sites that convert. Fast, accessible, on-brand. Built with modern tools and an obsessive eye for the details that make a brand feel real.
- Marketing sites & landing pages
- Launch campaigns and microsites
- CMS-backed editorial workflows
- Lighthouse 100s as table stakes
Product Direction
Fractional product and technical direction for founders who need a thinking partner. I help you decide what to build, in what order, with what stack — and stay close to make sure it actually ships.
- Product roadmaps & prioritisation
- Technical architecture decisions
- Vendor and tool selection
- Fractional CTO engagements
Hi, I'm Paulo.
AI-native studio.
One operator.
Nuno is a one-person studio. I plan, design, and ship software using AI as my primary build tool — orchestrating Claude, GPT, and the modern stack to deliver in weeks what traditional dev shops quote in quarters.
I'm not a typist. I'm the architect, the product mind, the quality bar. My job is deciding what to build, how it should work, and making sure every output is something I'd put my name on. The AI types. I think.
Based in Australia, working with founders globally who want speed, transparency, and one person who owns the outcome end-to-end.
A simple cadence,
followed religiously.
I don't reinvent the wheel for every engagement — over six years I've found a rhythm that consistently produces good software. Here it is.
Discover
Workshops, interviews, and a hard look at what you actually need to ship. Usually a 45-minute call is enough.
Design
Wireframes, prototypes, and architecture sketches you can prod, push, and break before any code is written.
Build
Weekly demos with working software. You see real progress every Friday, every time.
Operate
I stay on after launch — monitoring, iterating, and evolving the product with you.
Tell me what
you're working on.
A short note is enough. I reply personally within one business day — usually with questions, sometimes with a plan.
