Display Software Engineer | Test Automation & Calibration Expert

I’m a Senior Software Engineer specializing in Display Engineering. My expertise lies in test automation, optical calibration, and defect detection. At Apple, I’ve developed instrumentation and test systems for products like Vision Pro, Studio Display, MacBook Pro, and iPhone. Currently, I’m part of the Display Software team, where I’m working on Pro features for Apple Displays. My experience includes working with spectroradiometer-based testing platforms, Display drivers hardware, calibration algorithms, and reliability stress testers that ensure display quality for millions of users. My work spans the entire software/Hardware stack, from PCB design and firmware to test software and data analysis to enable manufacturing displays at scale.
