The harder the problems, the louder they call.
You always need a truly senior developer like me in a team. Being senior not only means to write stable and maintainable code but also, have an eye on how the team works. Is it a team or just a group of individuals? Therefore, apart from 40+ years of programming, I also have acquired skills such as facilitation and agile principles.
But let us not stop there, a team must also understand the "why" behind their work. With me in the team, product management have a speaking partner that understands their context.
You can hire me! I work at Agical (Stockholm) https://agical.se.
