Lead developer here, In my experience it's been: - Setting up the dev team for success by helping select language/framework/tech stacks - Helping other devs, sharing knowledge, training, tools - Encourage good developer habits, testing, OOP/OOD/patterns where needed etc. - Get team input and be point of contact with upper management - Plan the technical/solution design/architecture of said app. Share with other team members, work through it, get everyone on board, setup foundation, go build. - A bunch more but that's a good start.
