About

Dragos Macsim

I work on the data side of AI: web scraping, dataset construction, and model evaluation. At Mindrift I build automated extraction pipelines and hybrid human/AI QA workflows for training data. Before that I spent a year at Scale AI benchmarking text-to-image models and evaluating conversational AI outputs for alignment and factual accuracy.

I'm finishing an MSc in Business Analytics at Bayes Business School, on top of a BSc in Information Management for Business from UCL. The dissertation is the last piece; after that, more time for building.

Outside work I'm shipping mytai, an AI fitness coach for iOS, and I run a small homelab. Away from a keyboard: football, powerlifting, and cycling around London.
