CNBC API Testing QA Engineer role:

Situation: As a QA Engineer at CNBC, I was responsible for testing APIs for our news and market data services that power our mobile apps and third-party products.

Task: My primary focus was on our Market Data API which provides real-time stock quotes and financial information. I needed to develop and execute automated tests to validate functionality, performance, reliability and accuracy of the API under different scenarios and load conditions.

Action: I created a Postman test suite for API testing using various techniques like boundary value analysis, negative testing and mocked responses. I also built integration tests between the API and our apps. For load testing, I used k6 to simulate production-level concurrent usage. Throughout testing, I logged defects, documented issues, and worked with developers to retest bug fixes.

Result: My API test automation and extensive testing resulted in the successful release of the Market Data API with minimal defects. The API met all documented specifications and performed reliably under peak loads. The development team was able to continuously improve and iterate the API thanks to my collaborative quality assurance approach. This enhanced CNBC's ability to deliver financial data effectively to customers.

In summary, robust API test planning, automation, execution, and continuous testing enabled me to validate and improve core services that CNBC products rely on. My API testing expertise helped maintain quality standards.

QA Engineering role at Amazon:

Situation: As a member of the QA team for Amazon's retail website, I was responsible for ensuring quality of new features and enhancements to the customer shopping experience.

Task: A major project I worked on was testing the implementation of Amazon's 1-Click checkout feature which enables customers to seamlessly purchase with a single click. My responsibility was to thoroughly test this mission-critical purchase functionality across browsers, devices, and user scenarios.

Action: I collaborated with the product team to create comprehensive test cases covering positive, negative, edge case, and integration testing. I built automated selenium scripts to efficiently validate multiple test cases across platforms. To measure performance, I monitored key user flows using New Relic during load tests. Throughout the testing phase, I documented detailed bug reports and retested fixes.

Result: My focus on end-to-end quality assurance resulted in the successful launch of Amazon 1-Click with minimal post-production defects. The feature significantly improved customer conversion rates. My effective test planning and automation enabled rapid validation of new versions during future sprints. My QA leadership was recognized for enabling on-time release of a flagship feature that meaningfully impacted Amazon's business growth.
