How I build Software?

"Just" writing code is no longer enough. Projects need to be scalable and enduring. My focus is on maintainability, clean architecture, and solving complex business logic without over-engineering.

Strict Quality Standards

Robust CI/CD pipelines, projects with hundreds of automated tests (unit, integration, and smoke tests), strict typing, clean code, and SOLID principles to ensure safe and reliable deployments.

End-to-End Ownership

Accustomed and comfortable handling everything: from brainstorming and picking the right stack for the occasion, to database design, queues, processing, up to deployment and bare-metal server infrastructure management.

Team & Culture

I enjoy environments that value deep architectural discussions, code reviews, and continuous learning alongside distributed teams.

"I can advertise my pages with peace of mind, I am absolutely sure that every lead will get the maximum value from them."

- Julio Leite, Owner of Pórtico

Who I am

Based in São Paulo, Brazil (UTC-3), with flexible availability for overlap with US East Coast and European morning hours. I communicate in English at professional proficiency: fluent in written and reading, and confident in spoken communication.

I have spent the last decade mastering remote work discipline to stay close to my family. All these years of asynchronous work have taught me to communicate more objectively and clearly.

I use AI extensively in my daily routine to optimize workflows, and I have my own platform for managing projects. I also develop solutions and platforms that utilize AI, ranging from chatbots to RAG integrations.
