What I'm looking for

I’m looking for an AI/ML data or evaluation role where I can apply multilingual annotation, root-cause analysis, and model response testing to raise accuracy, relevance, and localization—while following clear SOPs and quality standards.

I’m an AI Data Trainer with experience in multilingual data annotation and AI/ML model training. I’ve trained Alexa using voice and text inputs while adhering to SOPs, with a focus on accuracy and quality in every label and response.

I discover error patterns in AI model responses and enhance performance through precise annotation, root cause analysis, and evaluation of Indian truthfulness, relevance, usefulness, and localization. I also compare model responses using preference generation methodologies to improve consistency and compliance.

Alongside training, I bring strong technical skills in Python, SQL, AWS, ETL, and BI tools. I’ve built and maintained data pipelines, implemented ETL processes for efficient data movement, and supported high-integrity workflows—plus experience delivering German customer support and troubleshooting for fast resolutions.
