What I'm looking for

I'm seeking entry-level Data Scientist or AI/ML opportunities where I can further develop and apply my technical expertise.

At Outlier, I evaluated LLM responses for accuracy, reasoning quality, safety, and adherence to guidelines. I compared outputs across models and used prompt engineering to assess response consistency.

I documented evaluation findings and analyzed recurring error patterns, contributing feedback for future model iterations and supporting data annotation and model alignment workflows.

At Infosys Ltd., I managed RHEL and Windows server deployments and retirements, improving deployment efficiency and reducing downtime by 30%. I also supported AWS account provisioning and migration, and automated deployment workflows using Jenkins and Bitbucket.
