Coffee Sessions #57 with Michael Del Balso and Erik Bernhardsson, The Future of ML and Data Platforms.
// Abstract
Machine learning, data analytics, and software engineering are converging as data-intensive systems become more ubiquitous. Erik Bernhardsson, ex-CTO at Better and former Spotify machine learning lead, and Mike Del Balso, CEO at Tecton and former Uber machine learning lead and co-creator of Michelangelo, sit down to chat with us today.
These two jammed with us about building machine learning platform systems and teams, the modern operational data stack, and how it allows more machine learning applications to thrive, and how to successfully take advantage of data in the process of building products and companies.
