What I'm looking for

I'm seeking Senior Test Analyst, Senior QA Analyst or roles combining manual and automated testing in the United Kingdom. I'm open to relocation and would require Skilled Worker visa sponsorship.

At EOH, I supported a multi-phase ETL programme for Investec Asset Management / NinetyOne, validating data transformations and database loads after an external vendor changed its source platform.

I compared high-volume vendor data files with database results using SQL, Excel and data-comparison tools. When exhaustive validation wasn't practical, I worked with project leadership on a risk-based approach and helped evaluate DataGaps, which proved substantially faster than existing Excel and Beyond Compare processes.

At EOH, I also tested for Old Mutual Wealth, analysing requirements and creating and executing manual functional, system and regression tests. Earlier, at SQS SA, I took ownership of a correspondence-focused testing project at Nedbank, including its test plan, coordination of junior testers and UAT sign-off.

I'm expanding my automation capability through hands-on projects with Python, Playwright, Pytest and Requests, including UI automation with the Page Object Model and automated REST API testing. I'm based in Durban and seeking Senior Test Analyst, Senior QA Analyst or roles combining manual and automated testing in the United Kingdom; I'm open to relocation and would require Skilled Worker visa sponsorship.
