Available to hire
I am a senior ML and data science professional with 7+ years of hands-on experience spanning model development, MLOps, code quality, and technical standard-setting. I specialize in building robust ML systems, defining rigorous QA frameworks, and translating complex outputs into clear guidance for both engineers and business stakeholders.
I’ve led QA processes, created gold-standard script libraries and evaluation frameworks, and designed SHAP/LIME explainability and RAG pipelines. I thrive on upskilling teams and delivering precise, practical feedback to improve outputs across projects and client engagements.
