What does a Full Stack Developer do?
Web development specializations exist for a reason, and the idea of a full stack developer isn't about being an expert in every possible technology there is. It's more about someone with a familiarity and an understanding in each layer, and a genuine interest in all software technology. It's also about being able to communicate intelligently with team members and to be a helpful asset if the situation requires it. Personal interaction and communication skills are necessary in order to manage and work with front-end developers and back-end developers.
Full stack developers understand how every part of the web development process takes place and can guide on strategy and best practices. These developers will have an increasingly important role in the web development of the future, and are able to look at the 'big picture'. They are knowledgeable with the server side as well as the client side’s user experience.
A full stack developer has knowledge in all stages of software development, and would be proficient, if not fluent, in:
- Server, Network, and Hosting Environments - this involves understanding what can break and why; appropriate use of the file system, cloud storage, and network resources; knowing application scale given the hardware constraints; and working side by side with DevOps
- Data Modeling - this involves knowing how to create a reasonably normalized relational model, complete with foreign keys, indexes, views, lookup tables, etc; being familiar with the concept of non-relational data stores and understanding where they shine over relational data stores
- Business Logic - having solid object oriented skills
- API layer / Action Layer / MVC - knowing how the outside world operates against the business logic and data model; using frameworks; being able to write clear, consistent, and simple to use interfaces
- User Experience - can step back and look at a process that needs seven clicks and four steps, and get it down to one click; write useful error messages
- Customer and Business Needs - having a grasp of what is going on when the customer uses the software; having a grasp of the business
To reach this level of qualification, it clearly takes years of work experience in different languages, roles, and industries. Because of this, full stack developers are few and far between, making them very employable and in-demand.
