What I'm looking for

I'm looking for remote, flexible AI evaluation, data annotation, or ML quality-assurance work where I can apply clear guidelines, assess model outputs, and help build reliable, well-tested AI systems.

I've independently collected, cleaned, evaluated, and annotated datasets for academic, research, and technical projects since 2021, verifying accuracy and consistency before use.

I build and test machine learning models in Python, MATLAB, and R, including CNN classifiers and generative models such as DDPM, WGAN-GP, and DCGAN. I also analyze signals using CWT and STFT, debug data pipelines, manage large-scale datasets, and write clear technical documentation in LaTeX. I'm motivated by AI safety and model-training work that helps build reliable, well-evaluated AI systems.
