Senior SDET at Afiniti (AI-powered enterprise software), Karachi, Pakistan. - Designed and built test automation frameworks from scratch in Playwright with TypeScript and the Page Object Model, creating reusable, modular test logic that became the team standard. - Authored 2,400+ automated tests across enterprise workflows (1,600+ in Playwright/pytest, 800+ on a proprietary simulation framework), reducing manual QA effort by ~40% and stabilising release cycles. - Built and maintained automated suites for functional, regression, smoke, and integration testing across web UI, REST API, and database layers. - Performed comprehensive REST API testing and backend validation with Postman and SQL against SQL Server and PostgreSQL, surfacing data-integrity defects that UI testing alone missed. - Ran end-to-end, integration, and load/performance testing on a real-time call agent simulation system, scripting scenarios of 10,000+ concurrent interactions. - Integrated Playwright and pytest suites into Jenkins pipelines with Docker-containerised execution, with JUnit XML and HTML reporting. - Set automation standards, reviewed test code, mentored engineers, and led defect triage and root cause analysis during critical releases. - Adopted Claude Code and GitHub Copilot for test scaffolding, edge-case generation, and refactoring.
