Building and shipping native iOS applications with a focus on architecture, performance, and long-term maintainability. I write code that scales, test critical paths, and take ownership of the full product lifecycle.
struct Developer {
let name = "Matheus Abrahao"
let role = "iOS Engineer"
let focus = ["Clean Architecture", "Privacy-First", "Local-First"]
var currentStatus: String {
"Building something cool... 🚀"
