Josua Paulo Zevallos Legonia

@josuapaulozevallosle

LLMOps Engineer at Landgorilla, building production RAG systems and AI agents for code analysis and infrastructure automation.

At Landgorilla, I designed an LLM-powered reporting system with the Google Gemini API and built an agent that checks Bitbucket pull requests against Jira tickets. I also created RAG pipelines for internal code repositories and an agent that handles natural-language requests for server and AWS operations.

At Zoluxiones S.A.C., on the BanBif project, I integrated AWS Lambda with Amazon Bedrock for compliance workflows and deployed a RAG system that checks pull requests against regulatory policies. My background includes Linux systems administration, cloud infrastructure, and security engineering, and I’m pursuing a Master’s degree in Artificial Intelligence.
