What I'm looking for

I’m looking for a role where I can own functional/system testing end-to-end, lead execution with the team, and work across networking/security domains. I want a fast, demanding environment that values problem-solving, automation, and accountability.

I’m a Staff QA Engineer with 18+ years of hands-on experience in Functional/System testing across Software/Finance/Mobile/Web/Networking domains. I’m flexible to work independently on any domain, and I bring strong time management, problem-solving, and self-motivation in demanding environments.

At Commscope, I focus on enterprise gigabit Ethernet access platforms, including Ruckus ICX7850/ICX8200 and related ICX families. My work covers System/Sanity/Feature test execution, SNMP testing (Set/Walk/get/getnext), and validating platform features, along with test plan preparation and helping team members technically.

Across previous roles as Senior Technical Lead and Technical Lead, I’ve worked deeply with networking protocols and security features—VLAN, STP/RSTP, DHCP, LAG, LLDP, VxLAN, OSPF, plus firewall/security and authentication flows including SCEP and CA-based certificate authentication. I’ve also led team members along with daily execution of testing activities.

I use a practical testing toolkit end-to-end: Python (Warrior Framework/HarmonyServer), traffic and validation tools like Spirent TestCenter and IXIA (IXNetwork), and QA workflows with CDETS/TIMS/PRRQ, JIRA, Confluence, Bitbucket, and TestLink. I work across Waterfall and Agile, including regression for maintenance releases and reproducing customer found defects to help resolution.
