About

Building systems that scale

Brazil 6+ years in software engineering Java / Spring / Cloud Investing in B3 & international markets

I'm a Senior Software Engineer with 6+ years building backend systems, cloud infrastructure, and ERP integrations for companies ranging from fintech scale-ups to enterprise manufacturers.

My core expertise is Java/Spring Boot microservices, event-driven architectures with Kafka, and integrating complex enterprise systems (SAP, Oracle) with modern cloud stacks. I've shipped systems processing millions of events per day and integrations that eliminated weeks of manual work.

Beyond the code, I'm interested in the intersection of software engineering and personal finance. I invest in Brazilian equities (B3), REITs, and international ETFs — and I write and make videos about this for other developers who want to build wealth while they build software.

Engineering & Investing

Software engineers are among the highest earners in Brazil, but most don't invest strategically. I write and make videos about building wealth as a developer — from understanding B3 and REITs to diversifying internationally with ETFs — using the same systematic thinking we apply to software.
