I have contributed to ongoing MultiMango Diamond workstreams within TrainAI / RWS, focused on multimodal data evaluation across image, video, and text datasets. The scope includes large-scale comparative annotation and rubric-based ranking of AI-generated outputs. Tasks involve detailed assessment of colour fidelity, contrast accuracy, shadow density, spatial registration, framing consistency, artefact and residual detection, motion stability (video), and fine-detail resolution. I perform structured qualitative evaluations aligned with evolving project guidelines and technical scoring frameworks. The project volume includes continuous production across multiple Purchase Orders, with sustained high-accuracy delivery under deadline-driven conditions. Outputs are submitted within structured BPP systems and tracked through formal invoicing cycles. Quality measures adhered to include strict rubric compliance, internal consistency checks, edge-case flagging, guideline version tracking, an

In this role, I annotated, evaluated, and curated diverse data types including text, images, video, and geographic information for generative AI and machine learning model training. I applied various labeling techniques such as bounding boxes, segmentation, and entity tagging, following detailed project guidelines and quality assurance processes. I also reviewed and scored AI-generated responses, performed QA checks, and delivered structured feedback to optimize workflows. • Consistently maintained high accuracy and productivity while adhering to project targets • Conducted research to support annotation accuracy and standardization across batches • Played a key role in inter-rater reliability assessment and ground truth dataset development • Provided valuable feedback to improve annotation processes and project documentation
