What I'm looking for

I'm seeking a senior individual contributor or lead role where automation quality engineering drives real product impact.

I built Cart2Cook.com, a live AI-powered recipe management PWA using Go, Supabase, Railway, Bootstrap, and Karate end-to-end automation.

At Acres Manufacturing, I pioneered backend automation for Kafka, database changes, and API contracts, while building Karate UI coverage for complex casino management workflows. I also automated scheduled testing and mTLS certificate renewal with GitHub Actions, created an internal Slack bot for manual test workflows, and mentored teammates on automation development.

Previously at Capital One, I redesigned an automation framework that reduced regression execution time by 80% through parallel execution and dynamic test data generation. My background spans fintech, SaaS, casino gaming compliance, API testing, CI/CD, and regulated systems.
