ABOUT ME

I'm Harrison Holt

I am an AWS-certified Software Engineer specializing in the intersection of Cloud Architecture, AI implementation, and Digital Accessibility. Most recently, I served as a Jr. Software Developer Intern at Eigennet LLC, where I contributed to production-ready applications using Python, Django, React, and AWS services like EC2 and RDS.

I am currently architecting an Intelligent Document Processing (IDP) pipeline using Amazon Textract and Bedrock to transform raw data into structured insights. I hold a B.S. in Computer Science with a minor in Psychology from Clemson University and am completing the UT Austin Full Stack Software Development Certificate.

My expertise is backed by four key credentials: AWS Certified AI Practitioner (New!), Solutions Architect – Associate, Developer – Associate, and DHS Trusted Tester for digital accessibility. As an active member of the IAAP, I ensure every system I build—from event-driven AWS backends to React frontends—is scalable, secure, and usable by everyone.

Current Goal: I am actively deepening my expertise in MLOps and am scheduled to sit for the AWS Machine Learning Engineer – Associate exam on April 15th.

This site was built with accessibility in mind and meets WCAG 2.1 AA standards, verified using Pa11y, Axe, Lighthouse, and WAVE, and tested with ANDI following DHS Trusted Tester methodology.

Outside of dev work, I'm passionate about military history and will never say no to a good book and a Dr Pepper.
