Summary
Builder of agent‑facing browser tooling and open‑source infrastructure: Magnus co‑founded Browser Use and is the principal maintainer/author on its core repositories. The project focuses on converting websites into structured, text‑like representations that LLMs and agents can reliably interact with, and it ships both open‑source libraries and a hosted cloud offering. github+2
Early‑stage founder with applied ML for transportation: Before Browser Use he co‑founded GreenWAI, leading efforts to optimize traffic lights using floating car data (product + ML) to cut CO2 and waiting times — combining practical ML with systems thinking and product leadership. thenetwork+1
Research‑oriented ML practitioner with hands‑on forecasting and interpretability work: His Cambridge CARES internship produced a Temporal Fusion Transformer forecasting agent and an extension to the darts library for analysing transformer attention weights, demonstrating both applied model building and a focus on interpretability. ac+1
