Carlos Santos
@caducodesSoftware Engineer & macOS Developer
I craft native macOS utilities in pure Swift 6 & SwiftUI leveraging direct Mach Kernel APIs and low-level system events. Concurrently, I build enterprise web platforms and distributed services at CI&T using Next.js, TypeScript, and Java / Spring Boot.
Flagship Native macOS Utilities
Open-source desktop applications built with Swift 6, SwiftUI, and low-level system frameworks.
OpenCleaner for Mac
v1.2.0 • Swift 6Native disk visualizer, Mach Kernel RAM optimizer & developer build purger.
Win+V for Mac
v1.1.0 • Swift 6Native clipboard history bringing the Windows + V workflow to macOS with cursor HUD & auto-paste.
Work Experience
Professional engineering history delivering enterprise systems and desktop software.

- •Collaborated closely with cross-functional global teams across product, UX, and backend infrastructure.
Independent Systems & macOS Software Developer
@Open Source Creator & Native macOS DeveloperCrafting high-polish, open-source macOS native utilities using Swift 6, SwiftUI, and low-level system APIs. Focused on high responsiveness, zero telemetry, Mach Kernel performance, and delightful desktop UX.
- •Authored and published OpenCleaner for Mac, featuring squarified treemaps and direct Mach Kernel RAM compaction.
- •Built Win+V for Mac, introducing zero-latency clipboard auto-pasting and global Carbon hotkeys to macOS.
- •Engineered hardware-reactive utilities leveraging Apple Silicon kinetic vibration sensors (Hit Mac Hard & Soft).
- •Implemented automated CI/CD DMG packaging pipelines using GitHub Actions and native shell build tooling.
