Dwaipayan Biswas
@dwaipayanbiswas
Senior SDET focused on scalable Playwright/TypeScript automation and reliable CI/CD test frameworks.
What I'm looking for
I build and lead end-to-end test automation that makes teams faster and systems more reliable. At SmartAsset, I migrated e2e infrastructure from Selenium/Cucumber to Playwright/TypeScript, creating architectural patterns and framework standards that powered future development.
I also design automation for complex business workflows—subscription management, bulk user provisioning, role-based access control, and payment integrations—while validating AWS Lambda endpoints and database integrity across multiple MariaDB instances. I’ve established CI/CD test pipelines (GitLab CI), mentored engineers transitioning from manual to automation, and previously led mobile and microservices QA, including production incident diagnosis through database migration and API call-chain analysis.
