Senior🎓
Top SchoolVasilis Lakafosis is a Principal Software Engineer with a decade-long track record building hyperscale data, network, and infrastructure systems at Meta, Uber, and Cisco. He architects petabyte-scale ingestion pipelines and unified data schemas that eliminated hundreds of engineering-years of duplication and became foundational to Meta’s global privacy and AI compliance programs. Known for rallying 20+ product and infra teams, he combines principal-level systems thinking with hands-on operator instincts—authoring Meta’s influential Data Understanding engineering post and mentoring senior engineers across domains. His prior work at Uber produced a patented data center automation that cut rack onboarding from hours to minutes and an open-source distributed network monitor adopted by hyperscale operators. Based in Los Angeles, he blends deep academic training (PhD work at Georgia Tech) with a pragmatic bias for shipping high-impact, organization-wide platforms.
