Hi, my name is

Angel Nieto Garcia.

I build system-level mobile features and high-performance apps used by millions.

I'm a software engineer specializing in Apple platforms — crafting beautiful, high-quality applications and the sensor-driven systems, real-time pipelines, and SDKs that power them. Previously at Apple, now building consumer experiences at PayPal.

AirPods Charging LED Detection

Designed and implemented a C++/assembly firmware framework for static and motion classification on custom Apple silicon, consumed by the Audio and AirPods teams. The framework provides device-state decisions at varying sample rates, enabling the Audio team to light the AirPods charging LED the correct color when the device is placed in its case.
