Work History
Software Engineer - 2
Walmart Global Tech India
10.2024 - Current
- Successfully validated resiliency of 100+ critical services prior to peak seasons, helping avoid potential multi-million dollar incidents.
- Integrated the chaos testing tool with CI/CD pipelines using Concord (Walmart tool) to enable automated resilience validation as part of build and deployment workflows.
- Built APIs in Go-lang to execute controlled fault injections such as CPU throttling, memory saturation, pod failures, network latency, and service termination.
- Collaborated with SREs and developers to define chaos test scenarios and system baselines for critical services.
- Guided the SRE and developers in DR tests and ensured application's resiliency is maintained.
- Automated end-to-end (E2E) testing using Playwright, covering critical user journeys in the developer platform UI to proactively catch regressions before deployment.
