Why is the line between juniors and seniors so often misunderstood?

Simple CRUD projects benefit from pragmatic developers focusing on speed and simplicity over complex architecture. As projects evolve beyond CRUD into service-based systems, senior developers become crucial for their architectural expertise. Defining clear context boundaries, abstractions, and scalability requires skills beyond just coding experience. The key difference between junior and senior developers lies in their architectural maturity and long-term maintainability considerations. Maturity in system evolution and teamwork also distinguishes senior engineers. Experience alone doesn't guarantee maturity, as some junior developers display more architectural understanding than seasoned coders. Evaluating engineering maturity is more valuable than simply counting years of experience on a resume. The author invites readers to share examples of junior developers excelling in CRUD projects and senior developers resolving complex system issues.
