Message

I built an AI Support Ticket Triage CLI in Python that classifies and prioritizes tickets using an LLM API, with structured outputs validated by Pydantic. Its evaluation improved from 47/50 to 50/50 correct fields, and the project includes cost controls, retries, and per-run logging.

At Strike, I triaged and validated more than 1,000 vulnerabilities using CVSS and business impact assessments, and automated workflows with Python and Bash. At Level 4 and Hackmetrix, I conducted web application and API penetration tests and security assessments, validated findings, and prepared technical reports.
