I build web applications, AI tools, and the infrastructure behind them.

At DUIT, that means production web applications, AI document analysis, and the infrastructure to run them. Outside work, it’s games and tools I wanted to exist.

Next.jsTypeScriptAWSCognitoDynamoDBCloudFront

I’m working on a production Next.js e-commerce site, moving components to server-side rendering, developing Playwright tests, and improving the Tailwind interface. A codebase audit removed 10% of its size through dead-code cleanup, alongside fixes for bugs and security vulnerabilities.

I’m currently building a website with AWS infrastructure, including authentication, request filtering, analytics, and email delivery. I manage infrastructure through code so changes are traceable. My AWS work also includes extensive EC2 use and Amplify. The website work also includes SEO and GEO optimization.

I delivered a full rewrite and redesign of another company website, support code reviews and production deployments, and was selected to lead the AWS rollout of our AI document-analysis pipeline.

OllamaGemmaFlaskDockerAWS EC2GitLab CI/CDpytest

I built a Next.js and Flask application for CMMC compliance workflows, provisioned EC2 infrastructure, containerized services, and deployed Gemma through Ollama as part of our team’s processing pipeline.

I also built the GitLab CI/CD pipeline that ran pytest on each commit and deployed to EC2 after tests passed. I worked with a four-person team that included cybersecurity professionals and DoD veterans, and represented the team at AWS Summit Washington, D.C.

What I’m building now.

Custom firewall and monitoring.

I built a custom firewall for the website, with CloudWatch logging and monitoring. CloudFront handles content delivery alongside the request filtering.
