@vamshigambir
Senior QA Automation Engineer specializing in Selenium Java, API testing, and CI/CD to deliver reliable releases.
United StatesWhat I'm looking for
I’m a Senior QA Automation Engineer with 9+ years of experience at Amazon and Charter Communications, where I increased automation test coverage from 40% to 85% and prevented 100+ high-severity defects across large-scale distributed systems.
I build automation frameworks and pipelines that make releases safer and faster. I’m expert in Selenium (Java, Cucumber, TestNG), Page Object Model, API automation, and CI/CD integration—cutting regression cycles by 50% and improving release reliability across multiple AWS environments.
My work focuses on measurable quality outcomes: automating validation for 200+ REST API endpoints across 20+ microservices, designing Jenkins CI/CD-driven daily regression runs, and using SQL validation scripts to catch critical billing and data issues before production.
I also bring leadership to the role—mentoring QA engineers, defining automation roadmaps, and standardizing QA processes to reduce duplicate coverage and improve team productivity. As an AWS Certified Cloud Practitioner, I support systems serving millions of users across 20+ microservices and high-volume transaction workloads.
