About

I am a Cloud Engineer with OCI and AWS experience and a thesis in financial audit RAG systems. I built secure landing zones across multi-account environments and won AWS GameDay (cloud security plus AI pipelines).

My background spans data annotation, search evaluation, and backend automation, giving me end-to-end understanding of how AI systems are trained and deployed.

Available for remote contract, freelance, and full-time work.
