Summary
👤
Senior🎓
Top SchoolChristopher Peplin is a Staff Software Engineer with 17 years of experience specializing in backend, infrastructure, and embedded systems, currently based in Pittsburgh. He blends hands-on engineering and occasional management, filling gaps across IoT, automotive diagnostics, and large-scale production services at companies from Ford and Uber to Zipline and Vanta. Notable open-source work includes refactoring pygatt for Bluetooth LE integrations and extending Arduino-Makefile support for Digilent chipKIT, reflecting deep practical expertise in BLE, embedded toolchains, and C-level diagnostic stacks. He pairs an MS in Information Networking from Carnegie Mellon with a maker’s attention to build systems and test automation, and often gravitates toward problems that connect low-level device behavior to resilient backend services.
