I’m João Pedro Helbel, a developer focused on building clean, data-driven experiences. I work across the stack with JavaScript/TypeScript, Python and Java (Spring Boot), and I love turning datasets into dashboards and insights. I’m currently leveling up in data analytics and crafting UIs with performance and accessibility in mind.
