About

From layouts to APIs, one project at a time.

I am a developer with 7+ years of experience building web applications with React, Next.js and JavaScript. Today I work as a Forward Deployed Engineer in fintech: close to the business, turning real needs into software, APIs and integrations that scale.

I enjoy the whole path from idea to product: interfaces and reusable components, API integrations, and backend work with Java and Spring Boot. I have worked in Agile teams alongside backend developers, QA engineers, product teams and business stakeholders, which made me a better teammate and communicator, not just a better coder.

I chose software because it lets me turn ideas into something real while I keep discovering what I am capable of. I love learning, sharing knowledge and taking on challenges that help me build reliable, valuable products, like Mercatto SaaS, my own sales platform for supermarkets and fruit & vegetable stores.
