Summary
👤
Senior🎓
Top SchoolChuck Mcmanis is a seasoned technology leader and management coach with 13+ years of formal experience and a career spanning seminal roles at Sun, NetApp, Google, Blekko/IBM and multiple startups where he helped scale systems, products, and teams. Trained as an electrical engineer at USC, he blends deep systems and embedded expertise (FPGA, ARM/STM32 contributions to libopencm3) with hands-on product and operations leadership across web, storage, and cloud infrastructure. He’s an inventor with a dozen-plus patents, an early Java pioneer who created the first Java web page on sun.com, and an expert witness on systems and Java matters. More recently he’s applied SDR and defense-focused architectures at Spectranetix while coaching engineers into effective managers, offering founder/CTO transition guidance without adding headcount. Known for pairing hardware curiosity (battlebot and hobby robotics) with pragmatic architecture and measurable operational improvements, he thrives where software meets physical systems.

Role in this project:Embedded Systems Engineer / IoT Developer
Embedded Systems Engineer / IoT DeveloperContributions:14 commits, 6 PRs, 47 comments in 2 years 11 months
Contributions summary:Chuck contributed to an embedded systems example project. They implemented and modified code for interacting with an SPI port to read data from a MEMS sensor and display temperature readings. The changes include initialization routines, register read/write functions, and example code demonstrating how to use the sensor and the SPI bus within the libopencm3 framework. The user also addressed code differences and adapted existing code to fit with the project requirements.
