Career growth in software engineering (and many other areas) is determined by the depth of knowledge and the breadth of expertise. A project can scale both horizontally, and vertically — which requires a different set of skills and experience in practical applications following both patterns. In practice, a senior developer can with less supervision. They can assess the risks, ask the right follow-up questions, determine the right workflow, analyze the possible bottlenecks and deliver a stable solution (usually well-documented and tested). solve almost any type of problem A junior developer can solve a . limited set of problems with a smaller subset of alternative solutions For example, an organization may need a simple blogging engine (just for the sake of an argument). The junior is probably familiar with one programming language, framework, or a platform. They will pick it right away and implement a semi-stable solution that solves most of the problems in certain use cases. A senior developer will take a . They will analyze the business goals and the technical challenges (expected amount of traffic, user roles and capabilities, different use cases and flow diagrams provided by the PM team). more prolific approach They will pick a certain framework that suits the business and budget constraints.

The management team can revise the options and pick the one that closely corresponds to the needs of the customer.

And if the senior developer has already spent several years within the organization, they can already assess the skill set of the other team members, their strengths and weaknesses, the standard workflow that the management takes and what would result in the best solution within the constrained requirements.
