Last year we wrote two blogs introducing you to our fantastic CTO Craft Coaches. Since then, however, we’re delighted to have welcomed a number of new coaches to CTO Craft, and we’re really excited to introduce them and all the wonderful skills and experience they boast.

Our coaches have a range of backgrounds and experience, and all can help you progress in your career and discuss many aspects of working in tech and the associated successes and challenges.

So, here are the newest CTO Craft coaches who can undoubtedly add value to your career and development.
