Rockstar🎓
Top SchoolJacob Alexander is a seasoned software engineer and input device architect with 17 years of experience building embedded firmware, cloud-native infrastructure, and manufacturing tooling. He co-founded Input Club and Kono Store, leading product and firmware development for mass-market USB NKRO keyboards and designing DSLs and flashing stations used in production. At companies like Datrium, VMware (now Broadcom), and Virtual Instruments he owned custom Linux distros, kernel maintenance, and complex build systems, bridging low-level C/C++/embedded work with Python and Go automation. An active open-source contributor, he extended Cap’n Proto Python bindings with asyncio support and improved the Kiibohd controller bootloader and USB DFU/ power management features. Based in San Jose, he combines hardware-adjacent firmware craftsmanship with large-scale systems engineering, often solving manufacturing and deployment problems most engineers never see.
