Full Stack Developer from Florianópolis crafting production-grade products from zero to market. I blend software engineering, product thinking, and business strategy to ship MVPs that scale.

Current Focus:

• 🤖 AI integrations (Claude API, RAG, agentic workflows)
• 🏗️ Scalable architecture (multi-tenant SaaS, microservices)
• 📊 Data-driven features (analytics, automations, integrations)

Philosophy: Technology that doesn't solve a real business problem is just elegant code. I ship fast, iterate based on user feedback, and obsess over impact.
