Experience

Software Engineer
Cisco Systems · Oct 2025 - Present
Enterprise Application Test Automation Suite:• Scaled the automated suite from 100 to 200+ tests using Playwright and TypeScript.• Raised coverage to 95% across critical user flows.• Ran headed-mode validations to catch UI and backend mismatches before CI execution.Agentic AI Security Compliance Pipeline:• Built an AI compliance pipeline that scanned a 168,000-file codebase and auto-generated JIRA tickets.• Reduced a manual 2-year review cycle to under 2 hours.• Designed a 12-phase workflow where only 4 phases invoke LLMs, after filtering 70% irrelevant files.• Improved reliability with consensus scoring across 3 parallel LLM calls and 5-run history checks.• Integrated 3 MCP servers (JIRA, GitHub Copilot, OpenAI Codex) to automate triage and produce developer-ready outputs.
