Sai Abheesh Annaiah

Applied Ai Engineer Intern @ Anthem Engine OS

About

I'm a Data Science Master's student at the University at Buffalo (Dec 2025), experienced in backend production and a growing focus on applied AI engineering.At MasTec Communications Group, I built and maintained 50+ production REST APIs in Java and Spring Boot for telecom operations, owning database design, CI/CD, and incident response for systems used by real field teams daily.Now at Anthem Nations, I build AI agent workflows using Claude and LangGraph, including a human-in-the-loop approval system with full evaluation pipelines, monitoring, and a JWT-secured developer API platform.I'm drawn to the intersection of AI agents, RAG, and production engineering, taking systems from prototype to something reliable enough to actually run on. Currently growing my skills in computer vision and multi-modal AI to round that out.
