Location: Fremont, CA (SF Bay Area) Remote: Yes Willing to relocate: No Technologies: Distributed systems, database architecture, F1/Spanner, infrastructure scaling, technical debt triage Résumé/CV: https://www.linkedin.com/in/joebar/ Email: joe@barrera.org Distributed systems architect. 30 years building infrastructure at CMU, Microsoft Research, Google. I help startups (10-100 people, Series A-C) avoid catastrophic scaling mistakes. I'd rather prevent your outage than debug it. What I've built: Mach kernel at CMU under Rick Rashid. Research systems at Microsoft BARC (Gordon Bell, Jim Gray). 9 years on F1/Spanner at Google. 4 USPTO patents in distributed systems. What I'm good at: "Your database architecture will fail at 10x scale, here's why and here's the fix." Technical debt triage with limited resources. Pattern recognition from decades of catastrophic failures. Currently thinking about LLM verification architectures and why static alignment is the VLIW of AI safety. What I'm looking for: Fractional CTO or senior advisory role (20-30 hrs/week). Series A-C, 10-100 people, real infrastructure problems.
