About Jeff's Place

Over the past few years, Jeff has been doing an increasing amount of mob programming with his students and customers. The results are unanimously positive: students stay engaged and teams remain focused.

Your session with Jeff will be a reflection of the interests and learning style of the mob as a whole, but chances are good it’ll be a lively and memorable event.

If the mob is a bit shy, we’ll move toward a strict navigator role, where requests funnel through a single navigator. This will ensure everyone starts to feel comfortable with talking others through the concepts we’re learning.

Join a lively mob and learn from a veteran developer and author. TDD, design, legacy, BDD, more!

Reach new peaks with our training.
