I'm a software engineer from Brazil with 9+ years of experience building production systems across artificial intelligence, healthcare, fintech, blockchain, energy, oil and gas, government, and international e-commerce.
My work sits at the intersection of AI systems, full-stack product engineering, and mobile development. I enjoy entering complex domains, understanding how the business works, and turning real problems into reliable software.
I started programming professionally in 2017 and grew from Frontend Intern to Junior Full-Stack Developer, Technical Lead, and Senior Software Engineer.
Throughout that journey, I've worked across frontend, backend, native mobile, integrations, deployment, and production support. I don't define myself by a single framework. I prefer to understand the problem first and learn whatever technology is necessary to solve it properly.
More recently, my work has focused on:
- Private and offline LLMs for organizations with strict data-privacy requirements.
- Retrieval-augmented generation pipelines for enterprise knowledge bases.
- Stateful AI agents built with LangChain and LangGraph.
- Qwen fine-tuning with domain-specific legal data.
- Document ingestion, indexing, contextual retrieval, and AI-assisted generation.
- Conversational AI integrated with WhatsApp, Messenger, Instagram Direct, and Twilio voice calls.
- AI-powered transcription, evaluation, feedback, and scoring workflows.
- Helped launch and evolve a major telemedicine platform used by more than 1 million people.
- Built native and cross-platform mobile SDKs with React Native, Swift, Objective-C, Kotlin, and Java.
- Worked on serverless digital banking, PIX payment journeys, and blockchain-based document verification.
- Developed high-traffic e-commerce systems and real-time industrial monitoring platforms.
- Led products from discovery and architecture through implementation, deployment, and production support.
- Frequently worked across team boundaries to unblock engineers and resolve critical production issues.

I care about:
- Understanding the product before choosing the architecture.
- Building software that works in production, not only in demonstrations.
- Keeping complex systems understandable for clients, users, and engineering teams.
- Learning unfamiliar technologies quickly when they are the right tool for the problem.
- Owning outcomes instead of stopping at the edge of a job description.
- Balancing delivery speed with maintainability and long-term product evolution.
I've worked with distributed teams and products serving users across Brazil, the United States, Europe, and Latin America. My experience spans highly regulated and operationally complex environments, including healthcare, financial services, enterprise AI, and industrial software.
I'm especially interested in opportunities where AI is part of a real product and business workflow - not just a thin wrapper around a model API.
