Generative AI Practitioner – Personal Projects
Self-Directed Work
- Developed multiple hands-on projects involving prompt engineering, model evaluation, and structured correction of LLM outputs, with focus on technical/physics-related reasoning tasks.
- Designed complex prompts aimed at stress-testing large language models, including multi-step physics problems, conceptual explanations, and error-inducing queries to observe failure modes.
- Built systematic evaluation frameworks (rubrics, scoring criteria, accuracy checks) to assess completeness, coherence, and scientific correctness of AI-generated answers.
- Performed iterative refinement of model outputs using domain knowledge in physics, identifying reasoning gaps and adjusting prompts to improve model performance.
- Explored different LLM platforms and configurations to compare model behavior, strengths, and weaknesses across tasks involving critical thinking and physics problem-solving.
