🚀 About Me

I believe that "fast" is a feature. With 5+ years of experience across the high-stakes sectors of Banking and Healthcare, I currently ensure Athenahealth systems remain resilient and scalable. I don't just execute tests; I architect performance ecosystems.

Whether I'm scripting intricate scenarios in JMeter, deep-diving into New Relic telemetry to isolate bottlenecks, or deploying Python-driven automation to eliminate manual overhead, my objective is singular: Peak Reliability. I thrive at the intersection of performance engineering, proactive monitoring, and intelligent automation.
