Oracle Technical Consultant · back-end & mobile developer · Barcelona, Spain 🇪🇸
Enterprise Oracle apps by day; typed, tested Python/FastAPI services, Android apps and native macOS tools by night.

Eleven Mac utilities in one lightweight, free, open-source menu-bar app:
a Dynamic Island for any Mac, notch or not · keep-awake · ⌘Tab by windows · window shortcuts & saved layouts
clipboard history that strips tracking from links · command bar · volume mixer with a 10-band EQ
a real performance monitor — per-core CPU, GPU, memory, disk, network, temperature — with alerts
menu-bar hider · app cleaner · OCR, colour picker, mic mute. Every shortcut is yours to change.

0.017–0.033 % CPU and 33–37 MB of real memory at idle · universal binary · macOS 14.2+ · no accounts, no telemetry.
It does the job of the seven utilities it replaces in your menu bar with 86 MB instead of 851 MB (RSS, same Mac, same method).

Per-core CPU, GPU, memory and network	A different volume for every app
Drop files, send them by AirDrop	iPhone-style card when your AirPods connect
