OtherImagePrompt Response Writing SFT
Designed and iterated multi-turn text dialogues with large language models (LLMs), focusing on emotional realism and instruction-following. Methodically analyzed AI-generated outputs for inconsistencies, emotional responses, and failure modes. Created prompts, performed adversarial dialogue engineering, and documented observations for improvements in AI performance. • Role-played diverse human personas and crafted realistic conversational scenarios. • Evaluated nuanced user intent, creativity, tone, and context in outputs. • Refined and adapted prompts based on evolving self-imposed guidelines. • Stressed LLMs to identify weaknesses in emotional intelligence and coherence.

Image Labelling & Annotation

LabelboxImageBounding BoxClassification
Labeled and annotated thousands of images from Kenyan smallholder farms to support agritech machine learning models. Drew bounding boxes around specific objects, including diseased leaves, pests, and fruits, for object detection tasks. Used classification techniques to assign categories such as crop health and crop type in farm imagery. • Outlined irregular shapes using polygons or masks for segmentation in satellite and drone images. • Utilized Label Studio for multi-label classification and CVAT for bounding boxes and masks. • Processed images covering various crop conditions, pests, and yield estimation requirements. • Contributed to reliable agritech datasets for computer vision model training.
