Gustavo Rivera Yeomans

Contract role supporting enterprise client's (Amazon) QA initiatives. Implemented TestRail to centralize QA workflows, enabling real-time visibility into test execution and improving cross-team coordination Built mobile and web automation frameworks using Selenium and Appium, reducing manual regression effort and enabling faster, repeatable execution of LLM-related test scenarios resulting in a 50% reduction in manual testing overhead. Built an AI-powered testing agent that generates structured test cases from use cases and acceptance criteria, reducing test design time from several hours to minutes and increasing coverage consistency Enhanced product quality by identifying and documenting 121 high-impact defects across 2 platforms.

Scaled QA organization from 8 to 20+ engineers (including 2 managers), enabling support for streaming products across 4+ platforms and significantly increasing delivery capacity across 3 engineering teams. Reduced testing tool licensing costs by $16K annually by consolidating frameworks and optimizing tooling across 4+ platforms (FireTV, Roku, iOS, Android, etc.) Led the integration of 2 separate testing teams into single, high-performing QA unit including the strategic planning and architectural design for modern automation framework, streamlining workflows, and improving overall product stability. Enhanced security and compliance through partnering with DevSecOps and audit teams, guiding and implementing Snyk in TestAutomation and SRE teams, and using both Snyk and xGitGuard for detecting and correcting security issues in Git for both teams.

Built on-demand test data generation pipeline using Bash, Ruby, Jenkins and Mockaroo, enabling reliable validation of complex systems and reducing test data setup bottlenecks Hastened continuous testing cycle by collaborating on DevOps infrastructure tasks, notably deploying and managing dedicated AWS Staging environment using Terraform, enabling seamless execution of automated tests.

Accelerated root-cause analysis and defect resolution across web and native applications through expertly debugging and investigating automation failures utilizing sophisticated tools like Splunk, adb, and Xcode. Engineered specialized, multi-language regression script by revolutionizing localization testing, fully automating manual process that previously consumed 2 hours across only 2 languages from the Customer Service team reducing it to 30 minutes testing across all 12 languages ensuring accurate translation across all those languages.

Founded and scaled Quepasa’s Quality Assurance team and processes, growing the team from a single employee to 8 members. Oversaw the promotion and cross-departmental training of team members transitioning into the QA team. Assisted business units in the implementation of standardized QA processes.
