Agentic AI & Platform Engineer
New York, NY [email protected] a.leonenko.me github.com/cyberkoder in/cyberkoder

Agentic AI & platform engineer with 10+ years building and scaling enterprise SaaS. I specialize in the systems layer of AI: MCP servers, model configuration & routing, retrieval, and agent orchestration, turning LLMs into reliable production software (not model training or research). Equally at home on 2-person startup teams and inside 100k+ employee enterprises, shipping across insurtech, healthcare, and legal tech.
