Summary
🤩
Rockstar🎓
Top SchoolAndrea Orru is a Senior Software Engineer in San Francisco with 11 years of experience building high-performance systems across startups and big tech, currently optimizing ChromeOS Lacros at Google. He blends backend systems work—designing scalable data pipelines, ad-bidding infrastructure, and SQL-queryable snapshots—with low-level interests evidenced by significant contributions to the Zig programming language and a cycle-accurate NES emulator. As a former engineering lead and CTO, he led migrations (Rails to Django), scaled pipelines by two orders of magnitude, and shipped patented proprietary technology. Comfortable across languages and stacks (C/C++, Rust-like Zig, Java, Python, Scala, Ruby, JS), he pairs a systems-level mindset with product-driven delivery and a history of tackling both performance-critical and platform-level problems.
