Hi there, I help AI labs and data teams ship cleaner training data, better-evaluated models, and analytics they can act on. Over the last 5 years I've trained and evaluated large language models for multiple AI labs, built annotation and QA pipelines, and led data teams in management capacity. On the analytics side, I've built churn and segmentation models and KPI dashboards (Power BI, Tableau, Sigma) that account managers use daily. What I can help you with: • LLM training & evaluation — response grading, pairwise/RLHF-style comparisons, red-teaming, edge-case curation • Data annotation & QA — labeling workflows, validation scripts, quality benchmarking across text, image, and video • Analytics & BI — churn/segmentation analysis, dashboards, and reporting in Python, SQL, and R Tools: Python (Pandas, NumPy, scikit-learn), SQL, R • Labelbox • BigQuery, Snowflake, Databricks • Power BI, Tableau, Looker, Sigma MSc in Data Science (University of East London), with certifications from Google and the University of Michigan. Let's talk about how I can help you get more from your data. Best, Dennis.
