Message

At Thinkipsystems, I manage user lifecycle operations in Active Directory and Microsoft 365 across multiple client environments. I also troubleshoot Windows, mobile device, printer, and network issues on-site and remotely.

At BuildingskillsNY, I developed and maintained automated test frameworks using Selenium WebDriver, Java, Cucumber, Jenkins, and Docker. I supported CI/CD testing pipelines on AWS EC2 and managed GitHub repositories and CI workflows.

At Cognizant/Capital One & Brinker International, I led automation initiatives integrating Eva Cobots with ATM and POS systems using Python and API-driven testing. I also designed and configured automation labs and expanded API testing with Postman.

My cybersecurity training includes the Google Cybersecurity Professional Certificate and hands-on projects in log analysis, packet dissection, Windows forensics, and Splunk incident handling. I’ve also worked in QA and test automation at Cognizant/PacificLife, Bloomberg LP, and Mayo Clinic.
