Freelancer Overview

​I am a highly analytical professional combining robust subject-matter expertise in Mathematics and Biology with practical experience in AI/ML development and advanced content moderation. Having successfully designed curricula that yielded a 100% student pass rate in national examinations, alongside hands-on technical experience building predictive machine learning models for healthcare and education, I possess the precise domain knowledge required to evaluate, ground, and refine complex AI outputs. ​Furthermore, my background as an international creative content contractor and chat moderator has sharpened my ability to perform deep tone analysis, linguistic evaluation, and sentiment tracking. Proficient in adhering to strict technical guidelines and passionate about data quality, I am exceptionally equipped for RLHF (Reinforcement Learning from Human Feedback), prompt engineering, and domain-specific data annotation that ensures AI models are accurate, safe, and contextually intelligent.

Stroke Prediction

Medical DicomMedical DicomClassificationClassification

Developed an end-to-end Machine Learning pipeline to predict the likelihood of a patient experiencing a stroke based on clinical, lifestyle, and demographic risk factors. This project addresses a critical healthcare challenge by leveraging predictive analytics to identify high-risk patients early, enabling preventative clinical intervention and reducing global stroke mortality rates. Technical Workflow & Implementation ​Data Preprocessing & Cleaning: Managed missing data imputation for critical health metrics (e.g., BMI, average glucose levels) and handled highly imbalanced target data using techniques like SMOTE (Synthetic Minority Over-sampling Technique) to ensure unbiased model training. ​Feature Engineering: Engineered and encoded categorical variables (e.g., smoking status, work type, residence type) and normalized continuous clinical data (e.g., age, hypertension, and heart disease history) for optimal algorithmic performance. ​Model Selection & Training: Supervised and evaluated multiple classification algorithms—including Logistic Regression, Random Forest, and XGBoost—to find the optimal balance between high sensitivity (recall) and precision. ​Performance Metrics: Evaluated model success using ROC-AUC score, F1-score, and Confusion Matrices, prioritizing high recall to minimize dangerous false negatives in patient risk assessment.
