What I'm looking for

I'm looking for a QA role where I can work on impactful products, continue growing in AI and automation testing, and contribute to a collaborative team.

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 LLMs, AI agents, conversational AI, and real time translation systems. I focus on end to end quality by designing test cases, validating outputs, identifying defects, and helping deliver reliable, high quality software.

In my current role in Karachi, I perform functional, regression, smoke, usability, load, and REST API testing using Postman and JMeter while tracking defects in JIRA and TestRail. I also validate LLM outputs, AI agents, speech to text, and real time translation systems across 4+ languages to ensure accuracy, reliability, and an excellent user experience.

My work style is collaborative and root cause driven. I work closely with developers and product teams during Agile sprints to identify issues early, reproduce defects, and support timely resolutions. I also bring a strong Computer Science and systems background from my experience as an Information System Audit (ISA) intern, where I developed analytical thinking and an understanding of software quality, business processes, and requirement validation.
