Senior Full Stack Engineer. 7+ years shipping Laravel apps, payment platforms, and AI-powered systems.

I build things that handle real money and real traffic. I also write about how developers actually use AI tools, because most of us are doing it wrong in predictable, fixable ways.

Based in Brazil (UTC-3). Open to relocation in Europe (Ireland, Germany, Spain, Italy) and remote roles worldwide.

Skyborn Information - my company, where I design automation pipelines for clients using n8n, TypeScript, and the Meta API, with OpenAI models and RAG architectures doing the heavy lifting.

AIRes Optimizer - a resume optimization SaaS built with Laravel, Inertia.js, Vue.js, and Stripe. It has a custom rich-text editor I built from a raw contenteditable element because existing editors couldn't do what I needed.

Nuance - an AI-generated text detector that uses statistical pattern recognition and mathematical modeling. Yes, I build AI tools and also build tools to detect AI. The irony is not lost on me.

I'm building a LinkedIn presence around AI tooling for developers. Not tips-and-tricks content. Articles with a point of view.

My core thesis: AI tools are not overhyped. But most developers, from juniors to seniors, use them wrong. Beginners expect magic. Senior devs skip context management and then blame the tool when output quality tanks.

Recent articles:

• "Did your stakeholders understand what they approved?" - how communication should be treated as a skill that should be constantly exercised to avoid being misunderstood
• "AI Won't Take Your Job. Bad Reviewing Might! " - the confidence problem with AI-generated code and why senior experience is a multiplier, not an obsolete skill
• "Helpful Assistants LIE. Honest Assistants SHIP." - why the "helpful assistant" persona in system prompts causes models to prioritize output over honesty
