Freelancer Overview

As a Chemical Engineering graduate (Cum Laude, UPLB) and a student researcher, I bring a highly specialized STEM background to AI training and data evaluation. My professional experience is rooted in rigorous academic research, technical R&D, and quality assurance. Certified in Six Sigma and experienced in advanced data modeling (R-Studio, Visual Basic) and process validation, I possess the high-level analytical problem-solving skills required to accurately evaluate, grade, and correct Large Language Models (LLMs) on complex mathematical, logical, and scientific reasoning prompts. What sets me apart is my dual expertise in hard sciences and strict editorial quality assurance. Serving as a former publication Editor-in-Chief equipped me with elite technical writing, fact-checking, and proofreading skills. This unique combination of advanced STEM knowledge and editorial precision allows me to excel in Reinforcement Learning from Human Feedback (RLHF), Supervised Fine-Tuning (SFT), and prompt evaluation. I am highly adept at identifying logical hallucinations, verifying factual accuracy against academic literature, and writing clear, comprehensive rationales for AI response grading.
