Nzisa Kiilu, a Kenyan tech expert, has disclosed that she helped build the powerful system engine that runs Google’s massive AI computers.
In a social media post shared on July 25, 2025, Nzisa expressed pride in her work, stating that many could not believe that a girl from Kenya built the orchestration engine behind the AI machine system.
“This wasn’t supposed to blow up,” she wrote in a post.
“For those asking, back in 2019, I joined Google to help scale our AI and infrastructure operations. I led the architecture and implementation of the execution engine that powers how we manage servers for both standard and machine learning workloads. It wasn’t glamorous — just real systems work, deep in the backend, built in close collaboration with our global data centre teams.”
These machines, more than a million in total, are used to train powerful AI tools like Gemini, Google’s answer to ChatGPT.
This year, Google plans to invest $85 billion to expand and improve the system even further.
