Vito Caputo
Software Developer at eero
San Francisco, California, United States
Summary
🤩
RockstarVito Caputo is a seasoned software developer with 11 years of hands-on experience building and optimizing low-level Linux systems, real-time graphics, and concurrent C code. Based in San Francisco, he brings deep expertise in GNU/Linux, pthreads, assembler, performance tuning, and minimalist, elegant designs that prioritize simplicity and safety. His open-source contributions span critical projects like systemd, CoreOS components, and go-systemd—where he fixed memory leaks, improved unit file handling, and backported kernel/systemd patches impacting containers and cgroups. Equally comfortable as a systems architect and solo hacker, he self-hosts much of his tooling and mixes off-grid homesteading with indie game jams and practical engineering. Notably, he modernized and fixed long-lived projects such as Schism Tracker and contributed to core OS boot/config tooling (Ignition), demonstrating a knack for both legacy code rescue and infrastructure-level improvements.
