Luke develops domain\-specific prompts, evaluates large language model responses, researches mathematics and statistics topics with AI tools, and provides feedback to improve response quality\. Luke also works as a Data Analyst–AI trainer at DataAnnotation, where he presents AI chatbots with diverse, complex mathematics problems and assesses model outputs for correctness and performance\. Alongside AI\-training work, Luke is a Data Entry Intern at NTA Enterprise Inc\. and a Mathematics Tutor at Marin Tutors\. Luke’s strengths include data analysis, data entry, critical thinking, problem solving, analytical skills, and communication\. Luke is proficient with the Python data stack, including Jupyter, Pandas, NumPy, and web scraping, and can take data science projects from data cleaning and wrangling through model deployment with business impact\. Luke has experience standardizing messy, inconsistent data sources building linear regression, random forest, and LSTM models and working independently on ambiguous technical problems\. In an earlier internship at NT Enterprise, Luke supported demand forecasting for apparel inventory planning and applied practical forecasting approaches to complex product data\. ## Services - Data Entry - Data Analysis - Critical Thinking - Problem Solving - Analytical Skills - Communication ## Highlights - Develops domain\-specific mathematics and statistics prompts and evaluates LLM responses as an AI trainer at Handshake\. - Uses AI tools to research mathematics and statistics topics and provides feedback on AI responses at Handshake\. - Creates diverse, complex mathematics problems for AI chatbots and evaluates model output correctness and performance at DataAnnotation\. - Extracts product data and compiles new Excel tables in sync with the CPSC’s new e\-filing system at NTA Enterprise Inc\. - Contacts suppliers to update NTA Enterprise Inc\.’s company factory list\. - Adds e\-file data to Excel database functionality to generate e\-file data with minimal data entry\. - Developed tailored tutoring curricula and homework assignments for children with special needs across subjects at Marin Tutors\. - Spearheaded an expansion of Marin Tutors services to local high school students, community college attendees, and students at the University of Southern California\. - Supported demand forecasting for apparel inventory planning during a previous internship at NT Enterprise\. - Can execute end\-to\-end data science projects from data cleaning through model deployment with business impact\. - Uses Jupyter, Pandas, NumPy, and web scraping as part of the Python data stack\. - Standardizes messy, inconsistent data sources for analysis and modeling\. - Has built machine\-learning models using linear regression, random forest, and LSTM approaches\. - Works independently on ambiguous technical problems with minimal guidance\. - Applies hands\-on technical skills to model building and data analysis\. ## Experience - **AI trainer Mathematics and Statistics at Handshake** (2025\-06\-01–present) — Developed domain\-specific prompts and evaluated LLM responses\.
