Hi, I'm Oscar Armas.

I’m a Staff ML Engineer based in Mexico. I specialize in building infrastructure and services for scaling Startups or Huge Enterprises.

Currently working at LexisNexis, focus on MLOps, and RAG Infrastructure.

I have worked in high-performance teams on very know companies, and I love sharing knowledge, whether professional or from my projects like @FakeGuru & @MiniDrafts
