Awards & Recognition
Achievements:
– Awarded Blink Bulldozer for Best Employee of the Month, Nov 2024.
– Secured 1st prize in AI Adoption Hackathon with a production-ready code.
– Received accolades for contributing to product and engineering demos.
Contributions (March 2021 – Present):
– Led organization-wide shift-left testing by building the first mobile test automation framework, performance testing framework, and in-house code coverage tool.
– Pioneered functional, visual, API, and data-driven (DB-ORM) testing by developing Cypress, Playwright, WebdriverIO (Appium), and MochaJS frameworks that became the foundation for 1,000+ automated regression tests.
– Built in-house alternatives to Mailosaur, Twilio, Percy, and Cypress Dashboard, eliminating licensing fees and saving the organization thousands of dollars every month.
Innovations:
– Introduced GHA Async triggers to optimize Kubernetes job execution, reducing GHA usage from 120,000 to 16,000 minutes monthly. Enhanced CI/CD pipelines with Continuous Testing (CT) for early defect detection.
– Implemented smart scaling for Dev pods using Kubernetes client APIs.
– Pushed Cypress console output into log files via shell output redirection and uploaded files from pods to S3.
– Built Kubernetes Cron-jobs with schedulers to clean up and trigger Slack notifications.
– Built custom YAML workflows using GitHub Actions strategy matrices to parallelize Cypress E2E tests on EKS namespaces, significantly reducing test duration and removing the need for the paid Cypress-io plugin.
– Set up smart-scale to scale up Dev pods using Kubernetes client APIs to allow more automation parallels to run and scale down.
