Dylan Kotzer · Full-stack & AI engineer

I build web products and AI systems.

I build web apps, browser extensions, and assistants that search content or use tools to complete tasks. I work on the interface, backend, and infrastructure, from early decisions through launch and support.

Open to freelance projects and full-time engineering roles.

Understand the system. Work with the people.

I take responsibility for the work I own and make it easy for others to review, use, and maintain.

Agree on the next milestone

Start with the problem, constraints, and a useful first release. Make the tradeoffs explicit before building.

Build in reviewable pieces

Follow the codebase's conventions, share progress, and use feedback from the people who know the product.

Make the handoff useful

Test the important paths and document how the system works, including its limitations and support needs.
