What I'm looking for

A QA / ETL Test Engineer role, remote or in India, where I can test data pipelines and applications using SQL, Snowflake, functional and UAT testing, and keep growing my test automation skills in Python and Selenium. I’m looking for an Agile team that values quality, clear requirements, and good collaboration with developers and business users.

At Infosys Ltd., I performed ETL and data migration testing for a Snowflake migration, validating data from CRM systems, legacy files, Oracle, and SQL Server. I used SQL to check source-to-target mappings, transformation rules, and record counts.

I also tested web, desktop, and UI applications, along with APIs and end-to-end RPA bots. My work included designing test cases, executing functional and integration tests, and logging defects.

In Agile / Scrum teams, I worked on ticketing tools including Enate, LEAPS, and APOC, and tracked defects in RTC (JAZZ/QM), JIRA, and Zoho. I used Generative AI tools to help draft test cases, SQL queries, and documentation.

I build test strategies and plans from requirements, covering functional, regression, SIT, and UAT testing with full requirement traceability. I also have foundational automation skills in Python and Selenium WebDriver, and I’m actively growing them.
