This talk was presented in Ghent, Belgium at ArrrrCamp 2014 and is an adaption of my How to be a Better Junior Developer and Ask vs. Guess Cultures talks.
Abstract:
Most developers focus on increasing their technical knowledge. However, there are many aspects to working as a professional developer besides coding proficiency. If you have interests or experience in other fields, you can pull in even those non-technical skills (like building relationships, project management) and immediately increase your impact on a project or team. When you mentor someone, you can help them play to their strengths and ramp up more quickly as a result.
