South AfricaWhat I'm looking for
I’m a results-driven Senior Test Analyst and QA Lead with 7+ years of experience delivering software quality assurance and data integrity solutions across financial services, banking, and enterprise technology.
I lead cross-functional testing teams, architect automation frameworks, and manage end-to-end testing lifecycles—especially for large-scale data migration and ETL programs. In my current FCMS work, I design 200+ end-to-end traceable test cases, coordinate SIT and UAT cycles, secure business sign-off, and drive defect resolution with development teams using Microsoft DevOps.
I also bring deep technical expertise in Selenium, Python, SQL, Hadoop, and Hive, backed by measurable outcomes: 99.9% data accuracy in multi-terabyte migrations, 100+ automated validation scripts, and significant reductions in resolution time. I’m ISTQB Certified (CTFL) and I’m open to remote opportunities worldwide.
