What I'm looking for

I’m looking for a QA/automation role where I can own end-to-end test planning, defect prevention, and validate AI/LLM features in Agile teams, with room to deepen performance and API testing.

I’m a detail-oriented Software Engineer (QA) with 2+ years of hands-on experience in manual testing for web, mobile, and AI-based systems, including LLM and real-time translation pipelines. I focus on end-to-end quality—designing test cases, validating outputs, and turning insights into faster, cleaner releases.

In my current role in Karachi, I designed and executed 200+ test cases to achieve 95% coverage across web and AI-based systems. I perform functional, regression, smoke, usability, load, and REST API testing using Postman and JMeter, while tracking defects in JIRA and TestRail. I also validated LLM outputs and speech-to-text and real-time translation systems, reaching 98% multilingual accuracy across 4+ languages.

My work style is collaborative and root-cause driven—I partner with developers during daily Scrum standups to identify issues and resolve critical defects efficiently. I also bring a strong CS and systems background from being an Information System Audit (ISA) intern and supporting QA planning through requirement analysis and acceptance criteria.
