About Me
HEY YOU,
I'm Arthur Vasconcelos, a 36 years old nerd from Brazil living in Stockholm, Sweden. I love coding and building things! I'm currently a Senior Front-End Engineer at Platform24, building digital healthcare experiences for Nordic and European markets. I'm also active in the open source community, building CLI tooling in Go and libraries in Python and TypeScript.
I have 16 years of experience as a developer. My main focus is front-end engineering — strong knowledge of TypeScript, Vue.js, and React — but I can work across the stack too.
