Rockstar🎓
Top SchoolDave Bailey is a Senior Staff Embedded Security Engineer with over two decades of software experience and eight years focused on embedded security at John Deere. He combines a strong academic foundation (MS in Computer Engineering from Iowa State) and CISSP certification with hands-on firmware and Linux/Unix expertise to harden connected machinery and IoT devices. At John Deere he progressed from senior software roles to architecture and security leadership, marrying product thinking with secure-by-design engineering. Outside corporate work he contributes to practical open-source tooling for embedded platforms—most notably firmware for a Raspberry Pi Pico-based USB Rubber Ducky—demonstrating low-level USB input emulation and async firmware patterns. Known for pragmatic debugging and cross-disciplinary collaboration, he brings both the rigor of formal security practices and the curiosity of a maker to complex, safety-critical systems. Based in Johnston, Iowa, he blends enterprise impact with hacker instincts to close the gap between offensive techniques and robust defensive design.

Embedded Systems Engineer / IoT Developer
Embedded Systems Engineer / IoT DeveloperContributions:7 releases, 4 reviews, 39 commits in 1 year 11 months
Contributions summary:Dave primarily focused on developing the firmware for a Raspberry Pi Pico-based USB Rubber Ducky device. They implemented core functionality, including the ability to parse and execute Ducky Script commands, and added support for features like a programming switch to control operational modes. The user also addressed bugs related to Windows line endings and enhanced the key parsing mechanism for more accurate command execution. Additionally, they introduced a button to trigger script execution and refactored code to incorporate asynchronous tasks for button monitoring and LED control.
