Zain Dana Harper
Systems engineering, developer tools, and practical operations.
Kent, Washingtonzaindharper@gmail.comharperz9.github.io
I build personal software projects: AI workstations, developer tools, evaluation infrastructure, and controlled-action interfaces. My career transition began in June 2026 after eleven years of full-time arboriculture, customer service, estimating, and field coordination.
Open to technical and nontechnical AI governance and evaluation roles. Willing to relocate to London; available for regular travel to San Francisco.
Sole proprietor since September 2026; no paid software clients.

Full CV and portfolio
The full CV retains the expanded record separately from the one-page resumes. It covers AI systems, compilers, security and verification tooling, graphics, technical writing, the earlier programming trajectory, and independent research.
Research and contribution record
Thirteen independent research records include EMET and other DOI-indexed papers and manuscripts. These records are not peer reviewed. The contribution record distinguishes merged, open, and closed without merge outcomes.
