About Me

I am an ML/Agentic AI engineer with 10 years of production experience at Intel and hands-on experience building LLM-based tools, multi-agent systems, and scalable data platforms. I transitioned from process engineering in semiconductor manufacturing to software development, giving me a unique perspective on solving complex operational challenges with modern AI and backend technologies.

I design reliable agentic systems that combine models, tools, and data into end-to-end multi-step workflows — with explicit planning, structured outputs, tool use, failure handling, and monitoring and observability. From an AI phone agent that completes real calls to a collection of Claude MCP servers, I focus on shipping practical AI systems with sound latency, cost, and accuracy tradeoffs.

I'm completing my Master's in Computer Science at Arizona State University (GPA 3.88), with coursework in Agentic AI, Statistical Machine Learning, and Data Processing at Scale, and I'm currently a Data Engineering Intern at Honeywell for summer 2026. My decade at Intel taught me the importance of reliability and maintainable architecture—skills I now apply to building intelligent, scalable systems.
