From assembling my first computer to building with AI agents.

My relationship with technology began when I was 11 or 12, at a computer shop next door to my home. I spent a lot of time there, helping format computers and reinstall Windows 95. I loved discovering how everything worked and seeing a computer come back to life after working on it.

At 14 or 15, I assembled my first computer. I bought the parts one at a time with the money I earned selling ice pops on the street. Memory, a hard drive, a motherboard. Each part was an achievement. That was the start of a love for the process of building that is still with me today.

That curiosity also led me to entrepreneurship. In Brazil, I started selling clothes, created my online shop and learned internet advertising. I travelled to buy products, sold through my website and served customers at home. I enjoyed being involved in everything: choosing products, setting up the operation and finding customers.

But another wish had been with me since childhood: learning English. That brought me to Australia. I arrived with little money, unable to speak the language and knowing nobody. I worked in construction, as a waiter, in cleaning and in other jobs while learning English and finding my way.

Over time, I started a room rental business that housed around 60 people. When I noticed that many residents needed electric bikes for delivery work, I developed a brand with two partners. We arranged the production of 40 bikes in China to bring to Australia.

The bikes arrived just as the pandemic began. Many residents returned to their countries, the apartments emptied and I kept paying rent, without understanding how long it would last. Within a few months, the money I had saved over years of work was gone. I had to return the apartments, sell the furniture and close both businesses.

It was a time to start again. I already had experience installing blinds, having worked my way up from installer to supervisor. I opened my own company and gradually rebuilt my life. Around a year later, I secured an installation contract at One Sydney Harbour. Over four years, I led a team of 12 people installing approximately 6,000 motorised blinds. I also built the systems we used to run the company.

When that project ended, I began spending more and more time on software development and artificial intelligence. I already had ideas and applications underway, and Cursor gave me a way to move those projects forward. I spent a year studying and developing intensively, often for ten or eleven hours a day.

At the end of 2025, I began trying to build my own local agent. I wanted to message it and ask it to carry out tasks on my computer. When I discovered OpenClaw, I found a tool very close to what I had been trying to build. I spent months studying, experimenting and putting agents to work. Today, I am continuing that journey with Hermes.

The tools change, but my motivation is the same as when I bought computer parts with the money from selling ice pops: understanding how things work and building something with them.

This site is where I share that process. Here you will find the tools I use, the projects I build and what I learn by putting AI to work in real situations.
