At Kingfisher plc, I design data validation strategies across datasets, ETL/ELT pipelines, and transformations. I use SQL, Python, and PySpark to validate data integrity and investigate quality issues across Databricks pipelines and Delta Lake tables.
At Qollabi, I tested front-end experiences and Salesforce integrations, and supported Playwright automation for critical user flows. I also validated CRM workflows, data integrity, and role-based permissions.
At Mad Collective, I maintained Cypress and JavaScript tests in CI/CD pipelines and performed backend validation with SQL. I led and supported a distributed QA team of six engineers and designed a structured QA onboarding process.
