Summary
🤩
Rockstar🎓
Top SchoolRuben Gutierrez is a Firmware Engineer at Microsoft with 12 years of hands-on experience building low-level software for datacenter hardware, focused currently on BIOS/UEFI development for Azure. He combines strong academic foundations—a 3.97 BS in Electrical and Computer Engineering—with practical firmware, FPGA, and embedded systems experience from university labs and internships. An active open-source contributor, Ruben has made notable backend contributions to Microsoft projects like winget-cli and the MSIX packaging SDK, improving package parsing, zip handling, and dependency integration. He demonstrates a pragmatic approach to tooling and automation, having built data-extraction pipelines for vehicle CAN data and migrated research workflows to cloud platforms. Known for debugging across C, Verilog, and system tools, he brings both low-level systems rigor and an appreciation for developer ergonomics. Based in Redmond, he pairs datacenter-scale firmware work with community-minded OSS contributions—sometimes summed up simply as "I do winget stuff," but with measurable impact on Microsoft's packaging and CLI tooling.
