About me

My journey into technology began with an unlikely foundation: a Bachelor's in Psychology from the University of São Paulo. While working in clinical practice and banking operations, I discovered my passion for solving complex problems through systematic thinking and automation. This realization led me to transition into software development, bringing with me a unique perspective on human-centered design and business logic.

Today, based in Madrid, Spain, I'm a Full-Stack Developer currently pursuing an MBA in Software Engineering at USP while building production-grade applications that bridge technical excellence with business strategy. My expertise evolved from frontend work with Vue.js/Nuxt.js to sophisticated backend systems using NestJS, PostgreSQL, and Drizzle ORM, complemented by AI workflow automation using n8n and LLM orchestration.

What sets me apart is my holistic approach to software development. Having worked across psychology, banking operations, and technology, I understand both the technical requirements and the human factors that make software successful. I specialize in e-commerce/ERP integration and cross-platform mobile development, creating solutions that not only work technically but also solve real business problems for international clients.

As an EU Citizen (Spanish) with immediate availability, I'm passionate about building scalable systems that make a difference. Whether developing middleware for Magento 2 and Shopify integrations, creating multi-language conference platforms, or automating complex business workflows, I bring the same dedication to understanding user needs and delivering measurable value through clean, well-documented code.
