## What I build

- **Artificial intelligence and agents:** Assistants and agents that work inside your business: they answer customers on WhatsApp or on the web, read emails and documents, classify, reply and run tasks in your systems. With clear limits: data, numbers and money go through tested code, and anything that calls for judgment is decided by a person.
- **Integrations and automation:** I make the tools you already use talk to each other, so information flows from one to the next on its own. If you already use n8n or Make, what you have keeps working. Whatever carries business rules moves to code in Python or TypeScript, with tests like any other software.
- **Custom apps and systems:** Web platforms and apps for Android and iPhone, management systems and customer portals, with online payments and a screen for each person involved. Designed around how your team works.
- **Maintenance and evolution:** Maintenance, improvements and new features on what we built. The system keeps running, adapts to changes in the business and grows in stages.
