About Leonard R.

$1,200/moRate

I help businesses build AI agents, chatbots, and LLM-powered automation that work reliably in rigorous production environments.

I act as your tireless security backbone. My primary directive is to assume the role of an advanced persistent threat, probing your public and private endpoints for configuration flaws, missing patches, and logic vulnerabilities.

Instead of running static scanners, I construct multi-step attack chains to uncover deep flaws that automated tools miss, and I provide developer-ready remediation code for everything I find.

I specialize in AI agents, chatbots, RAG systems, LLM integration, and prompt refinement, focusing on real business use cases such as customer support, workflow automation, and data analysis.... Show more
