About

Professional summary

I am a Software Quality Assurance Engineer with experience testing web applications, REST APIs, and third-party integrations across education, assessment, hiring, payment, and loan disbursement products.

I design test strategies, create test cases, execute functional and regression testing, and validate releases to ensure reliable user and business-critical workflows. My work has helped reduce manual testing effort by up to 60% and post-release defects by 20%.

I build automated regression suites using Pytest, Cypress, Playwright, and Karate, integrating reusable test scripts into CI/CD pipelines to improve deployment reliability and release speed.

My backend engineering background in Java, Spring Boot, JPA/Hibernate, and SQL helps me perform stronger API contract testing, investigate integration issues, and identify root causes efficiently.

I work effectively in Agile teams, collaborating with developers and stakeholders on defect lifecycle management, UAT planning, release validation, technical documentation, and continuous quality improvement.
