RLHF

Freelancer Overview

I am a physicist with a decade of experience in experimental research, data analysis, and scientific software development, with a particular focus on high-precision measurement and signal processing. My background includes building and automating data acquisition pipelines, developing Python-based analysis suites with automated quality control, and implementing advanced statistical methods such as Bayesian inference and MCMC for modeling and data interpretation. I have hands-on experience with large, complex datasets from sensors and imaging systems, and have led projects that required meticulous data annotation, real-time denoising, and calibration to ensure high data quality for downstream analysis and machine learning applications. My technical toolkit includes Python (NumPy, SciPy, Pandas), C++, MATLAB, and tools like Jupyter, Docker, and Git, enabling me to create reproducible, scalable workflows for AI training data preparation in scientific and engineering domains.
