Gretchen Walker is a Wireless Bluetooth Software Engineer at Apple at Apple. She possess expertise in ios development, c++, python, java, html and 13 more skills. She is proficient in French. Colleagues describe her as "I've worked with Gretchen on various projects — both internal and external-facing — at Punch Through over the years, and Gretchen's really proven herself time and time again as our subject matter expert when it comes to iOS development and Apple's Core Bluetooth framework. She's able to hold her own as the sole/primary iOS contributor for a long-running medical device software project and she's accumulated a wealth of experience working with difficult APIs like CryptoKit and Keychain. Gretchen is a strong leader and communicator, having led a long-running project in the past and navigating difficult project situations. Recently, Gretchen's contributions to our project team's system architecture and planning have been instrumental in getting feature work fully defined and unblocked. Gretchen has served as a mentor for interns and junior engineers, and her passion for teaching others also permeated externally as she was the author of our company's excellent Core Bluetooth blog post that so many around the world reference when learning about iOS Bluetooth development, and I seem to also recall her being on a podcast to talk iOS Bluetooth topics with others! Gretchen is very kind and she demonstrates a high level of empathy for others. I've honestly learned so much about putting myself in others' shoes while working with her. She's also a great listener — despite our timezone differences, she always makes time for a quick chat. Gretchen is such an incredible team member and friend to be around, and I will absolutely miss working with her."
