What I'm looking for

I seek an AI Trainer role where I can apply dataset curation, annotation, prompt engineering, and model fine-tuning within a collaborative team focused on improving AI accuracy and continuous learning.

I am a detail-oriented machine learning practitioner focused on dataset curation, annotation, and model fine-tuning. I combine a hands-on approach to data handling with practical experience in model training and prompt optimization.

During a Machine Learning internship I preprocessed datasets with Pandas and StandardScaler, applied PCA for dimensionality reduction, and developed a DNN using TensorFlow and Keras with LeakyReLU, batch normalization, dropout and early stopping. I achieved strong predictive performance in a multi-output regression task, reaching 95% overall accuracy for acoustic property predictions.

I have built a PySpark ALS-based recommendation system for large-scale user-item data and completed a Hands-on Approach to AI course (July–October 2024). I am seeking an AI Trainer role where I can improve AI accuracy through high-quality training data, prompt engineering, and model refinement.

Machine Learning Intern

CSIR-National Physical Laboratory

Apr 2024 - Jun 2024 (2 months)

Developed DNN models to predict multiple acoustic properties from a 5,000-row dataset, achieving 95% overall accuracy and reducing overfitting via batch normalization, dropout, and early stopping. Preprocessed data with Pandas and StandardScaler and applied PCA to improve model efficiency.
