About Me

Hector Hernandez - Backend Engineer

I am a software application engineer with 10 years of production experience at Intel, where I specialized in building and optimizing large-scale ETL pipelines and data systems. I transitioned from process engineering in semiconductor manufacturing to software development, giving me a unique perspective on solving complex operational challenges with modern backend technologies.

Currently pursuing my Master's in Computer Science at Arizona State University (GPA 3.75), I focus on distributed systems, data processing at scale and applied AI. My coursework in Statistical Machine Learning and Agentic AI complements my production experience in Python, C#, and building enterprise data pipelines.

I'm passionate about applying AI to streamline both professional and personal workflows. From building AI-powered categorization into my finance tools to creating Claude MCP servers that extend AI assistant capabilities, I'm constantly exploring how machine learning and LLMs can automate repetitive tasks and unlock new possibilities. My decade at Intel taught me the importance of reliability and maintainable architecture—skills I now apply to building intelligent, scalable systems.
