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, AWS (Athena, Glue, QuickSight), and crafting UIs with performance and accessibility in mind.
Main technologies and tools I use on a daily basis.
A few highlights. More on my GitHub.
