Freelancer Overview

I am a Machine Learning Engineer with over 6 years of experience developing AI systems and creating high-quality datasets for training machine learning models across NLP, computer vision, and generative AI. My work has involved designing and curating structured training datasets, including annotated images, segmentation masks, and multimodal datasets used for deep learning pipelines. For example, I built an in-house dataset of sketches paired with 3D models to train reconstruction models and worked with segmentation datasets for defect detection and satellite imagery, where precise labelling and mask generation were critical for model performance. In addition to dataset creation, I have experience evaluating and improving AI model outputs, particularly for large language models and generative systems. My research collaborations and published work in conferences such as CIKM, PAKDD, and IEEE MIPR involve training and benchmarking models on curated datasets, ensuring annotation quality, and validating model outputs. With strong expertise in Python, PyTorch, and large-scale ML pipelines, I bring a combination of technical modelling skills and hands-on experience with AI training data workflows, making me well-suited for tasks involving data labelling, dataset validation, and AI model evaluation.

Labeling Experience

Data labelling using OpenFace for emotions recognition

ImagePoint Key Point
Created a multimodal engagement dataset for analyzing student behavior during online learning sessions. Designed an experimental setup where students watched curated video clips to induce emotional and engagement responses. Collected multimodal signals including facial expressions, gaze direction, and temporal behavior patterns. Used OpenFace to automatically extract facial action units, gaze vectors, and head pose features. Implemented annotation pipelines to label engagement levels and emotional states across temporal video segments. Structured the dataset to align facial features, gaze signals, and timestamps for training engagement prediction models.
