Vineeth-kunju
Over a twelve-month period, contributed to the govuk-one-login/performance-testing repository by designing and expanding a robust performance and stress testing framework for user onboarding, authentication, and API endpoints. Leveraging TypeScript, JavaScript, and K6, developed and refined load, spike, and peak test profiles to simulate realistic traffic patterns and validate system scalability. Enhanced test automation, data management, and scenario configuration to improve reliability and early detection of regressions. Iteratively updated test suites to align with evolving product flows, strengthened JWT payload handling, and streamlined test execution. This work enabled more accurate capacity planning and supported production readiness for critical identity services.

Mar 1, 2026March 2026: Upgraded the stress testing framework for govuk-one-login/performance-testing with expanded coverage across user sign-up, sign-in, OLH, and API endpoints. Delivered new stress profiles (I8 Spike for SIS; I9 profiles), stress test utilities, and expanded load configurations; updated timing with a 60-second timeunit. Implemented targeted fixes including signup scenario corrections and typo fixes, and added CIMIT API stress profile along with OLH profile refinements. These changes increase test coverage, reliability, and early detection of performance regressions, directly supporting scalable onboarding and authentication flows.
