Walther Gonzalez
@walthergonzalez
University physics lecturer and AI trainer specializing in LLM evaluation, prompt engineering, and problem-solving.
What I'm looking for
I am a university lecturer with over a decade of experience teaching physics and mathematics, focused on problem-based learning that trains students to analyse, model, and solve quantitative problems. I design exercises, labs, and tutorials across undergraduate and graduate curricula.
In parallel, I work as an LLM trainer and quality analyst, creating prompts and evaluation datasets, reviewing operator-produced training data, and delivering structured feedback to raise dataset quality and model reliability. I have designed prompts for advanced mathematics and physics tasks, authored complex problems, and compared model outputs to identify reasoning and numeric failures.
My work bridges academia and industry: I have taught at multiple universities, contributed to STEM research and publications, and supported instruction-tuning and chain-of-thought guidance to improve model outputs. I bring rigorous technical skills in LaTeX and Wolfram Mathematica, multilingual communication, and a strong record of curriculum and dataset quality improvement.
