Data Annotator

Turing

  • Wrote category-specific image prompts and scored 5,000+ model outputs using Apple’s RLHF rubric.
  • Built and applied prompt sets; evaluated grounding, reasoning, and compliance on every response, following structured guidelines.
  • Conducted jailbreak, bias, and prompt-injection tests; logged errors, inefficiencies, and edge conditions.
  • Reviewed model transcriptions and intent alignment; produced clear outcome notes marked as success / partial / failure.
  • Performed frame-level tagging of clicks, drags, and UI states; generated timestamped annotations to train action-sequence GUI agents through video annotation.
  • Created LaTeX/Markdown ground-truth pairs for OCR models; QA’d every sample for loss-free parsing and consistency.

Prediction of AQI of Lahore City using Machine-Learning Models

  • Compiled a 20-year dataset (2003–2022) from Copernicus CAMS; five pollutants plus temperature, 65,000+ rows.
  • Bench-tested ARIMA, SARIMAX, STL-Decomposition, and XGBoost; evaluated with MSE and Dynamic-Time-Warping.
  • Selected ARIMA (0,1,0) as best model, reducing forecast error by 30% vs. alternatives; produced structured performance summaries.
