At CMIT Solutions / Berkshire Hathaway Specialty Insurance, I support enterprise users with Microsoft 365, identity and access, endpoints, and business applications. I also built an AI-assisted profitability analysis using HatzAI and Autotask data to identify ticket and labor drivers, validating AI-generated guidance before applying recommendations.

At SimpliSafe, I owned quality validation across mobile, web, API, backend, and connected-device workflows. I created and led end-to-end bug bashes, helped build an in-house regression program, and trained 11 employees on repeatable testing and release validation.
