I am writing to express my interest in opportunities within your organisation for roles related to ETL Testing, Data Migration Testing, or Test Leadership. With over 13 years of experience in data warehouse, data lake, and ETL testing across banking, insurance, retail, government, and media sectors, I bring extensive experience in validating complex data platforms and leading quality assurance initiatives for large-scale transformation programs. Currently working as a Test Lead at Tech Mahindra for Suncorp, I lead QA activities for enterprise-scale data migrations from Netezza to AWS Redshift as part of a major divestiture program. My role involves defining the end-to-end data testing strategy, validating ETL pipelines in Databricks, ensuring transformation accuracy, and implementing automated reconciliation using SQL and Python. I also work closely with cross-functional teams to ensure data integrity across business and regulatory requirements. Throughout my career, I have successfully delivered testing for complex data transformation and integration initiatives, including cloud migrations, Salesforce implementations, and large-scale data warehouse programs. I have strong hands-on experience with technologies such as SQL, PySpark, Databricks, Informatica, AWS, and API testing tools like Postman. In addition, I have led SIT and UAT phases, created test strategies, and mentored testing teams to ensure high-quality releases in Agile environments. What I bring to an organisation is not only strong technical expertise in data validation and ETL testing but also leadership in driving testing strategy, improving automation of data checks, and collaborating effectively with business and technical stakeholders. I would welcome the opportunity to contribute my experience to your team and support the successful delivery of data-driven transformation initiatives. Thank you for considering my application. I look forward to the possibility of discussing how my skills and experience align with your organisation’s needs.
