What is a full stack developer

A full stack developer is a web development professional who is skilled in both front end and back end coding. They work on the full stack of technologies needed to build and deploy complete web applications and sites.

Full stack developers are critical members of web dev teams because they can:

• Switch between front end and back end tasks as needed
• Identify and fix problems that span both sides of a project
• Prototype and launch MVPs independently

This comprehensive guide will demystify what these versatile developers do day-to-day. We’ll cover the key programming languages, frameworks, and soft skills needed to thrive in this career.

You’ll learn the differences between full stack, front end, and back end roles. We’ll also explore full stack education requirements, salaries, future outlook, and more. Whether you’re new to coding or looking to switch careers, this guide will get you started on the full stack path.

What is a full stack developer responsibilities

Full stack developers handle a wide range of critical responsibilities across the entire web development cycle. Their core duties include:

Front End Development

The front end of a website or application includes everything users see and interact with directly in their browser or on their device.

Full stack developers use HTML, CSS, JavaScript and frameworks like React to code the visual user interface and front end logic. Key responsibilities include:

• Coding responsive layouts that adapt to different device sizes
• Implementing slick animations and interactions with JavaScript
• Building reusable front end components
• Creating an intuitive, seamless user experience
• Optimising site speed and performance
• Implementing SEO best practices

Back End Development

The back end refers to the behind-the-scenes server environment that powers the application.

Full stack devs use languages like Python, Node.js and Ruby to code the back end. They are responsible for:

• Setting up and configuring web servers
• Creating APIs for front end integration
• Building scalable database architecture with SQL and NoSQL
• Implementing robust security and authentication
• Writing clean, maintainable back end code
• Optimising application performance and speed

Collaboration with Specialised Developers

While skilled across the full stack, these developers also collaborate with specialised front end technologies, back end, and full stack experts across their team.

They communicate requirements, discuss solutions, and ensure seamless integration across the entire application stack.

Prototyping and Launching MVPs

Due to their wide skillset, full stack devs are uniquely equipped to prototype and launch MVPs quickly.

They can take an initial idea or concept, then independently develop and deploy a “minimally viable” app for stakeholder testing and feedback.

Rapid prototyping allows teams to validate concepts before investing in full production development.

Working Across the Full Technology Stack

As the name implies, full stack software developers have competencies spanning the entire software technology stack.

Unlike front end or back end-only developers, they can flow seamlessly between front end, and back end web development, database and server tasks as needed within a project.

This big picture view allows them to develop solutions that optimise the full end-to-end user experience.

Required Skills and Expertise

Full stack developers need to master a diverse array of technical and soft skills to succeed in the role.

Front End Skills

Full stack devs must be fluent in the core languages for building the visual front end of web applications:

• HTML: For structuring and presenting content
• CSS: For styling and layout
• JavaScript: For implementing complex user interactions

They should also be competent with popular frameworks like:

• React: For building reusable UI components
• Angular: For building dynamic single-page apps
• Vue: A progressive framework for UIs

Experience with tools like Git, Webpack, and Chrome DevTools is also essential for smooth front end and backend development workflows.

Back End Skills

On the back end, full stack developers work with:

• Python and Ruby for general web app development
• Node.js for building high-performance real-time apps
• PHP for server-side scripting

They also need to master essential database technologies, including:

• SQL databases like PostgreSQL and MySQL
• NoSQL databases like MongoDB

API development, server configuration, caching, and optimization are other key back end competencies required.

Key Soft Skills

Full stack developers also need certain soft skills and traits to excel:

• Communication: They must collaborate seamlessly with specialized front/back end devs. Clear verbal and written communication is essential.
• Time management: They often juggle multiple tasks and projects simultaneously. Strong time management abilities are critical.
• Problem solving: They must be adept at diagnosing and debugging issues across complex, interconnected systems.
• Creativity: They need to come up with innovative solutions to complex problems.
• Teamwork: They collaborate closely with other developers and team members. Cooperative team skills are a must.

Rapid Learning

With the fast pace of change in web technologies, full stack developers must be able to quickly pick up new languages, frameworks, and development techniques.

Willingness to continuously learn and master new skills is essential.

Understanding Full Application Architecture

Full stack developers need to understand how all the front end, back end, database and networking pieces together into a complete working web application.

This complete architectural vision allows them to build integrated solutions that improve the overall user experience.

Educational Background

Choosing the right education is key if you want to become a full stack developer. There are a few different options to get the skills you need:

Computer Science Degrees

A 4-year computer science college degree gives you a very thorough foundation. You’ll take important classes like:

• Algorithms and data structures – How to organise and work with data
• Software engineering basics – Best practices for writing code
• Operating systems design – How OSes like Windows and MacOS work
• Programming languages theory – The concepts behind languages like Java and Python

You can specialise through electives in areas like databases, web development, and mobile apps. A CS degree builds deep knowledge and well-rounded coding abilities. The downsides are the time and cost commitments.

Self-Directed Learning

Some developers learn through self-paced online platforms like Coursera, edX, and Udemy. With focus and practice, you can gain skills without formal credentials. But showing employers you have abilities is tougher without a degree. Building portfolio projects is essential.

Coding Bootcamps

These intensive courses aim to prepare you for developer roles in 3-6 months. The focus is building real-world skills by working on projects and collaborating.

Key advantages of bootcamps:

• Learn skills quickly through hands-on work
• Create portfolio pieces and make connections
• Specialise in front end, back end, or full stack
• Much lower cost and faster than a 4-year degree

Bootcamp grads can be just as ready for entry-level jobs as CS degree holders.

Work Experience

No matter how you learn, applied experience via internships is highly valued by companies hiring. Working on real apps shows you can deliver production-ready code, collaborate well, and adapt fast.

Personal coding projects that show passion and drive are also great portfolio additions. Ongoing learning is essential in this fast-changing field.

Overall, combining theory and practical skills develops the expertise to thrive as a full stack developer.

Day-to-Day Work Environment

Full stack developers have a busy and collaborative work life. They work with different teams to build products.

Working with Different Teams

Full stack developers spend a lot of time working with other teams:

• Front end developers – Work together to make user interfaces that are easy to use and nice to look at.
• Back end developers – Work together on servers, databases, and the behind-the-scenes parts of apps.
• Designers – Partner with designers to add prototypes and new features.
• Product managers – Coordinate with PMs to agree on priorities and plans.

Working with all these teams helps full stack developers understand how all the parts fit together.

Juggling Multiple Projects

Full stack developers often work on many projects at the same time. For example, they may be:

• Fixing bugs in one product
• Adding new stuff to another product
• Testing ideas for a third product

This requires strong skills in switching between tasks and doing multiple things at once.

Fast Pace of Work

Most full stack developer teams work very fast with quick updates. New code can be written, tested, and launched in days or weeks.

This fast pace means teams can add value quickly and use feedback fast. But full stack developers need to be able to change plans and priorities quickly.

Always Learning

To keep up with changes in web development, full stack developers must always be learning. This means staying up-to-date on new tools, best practices, and more.

Some ways they keep their skills current are:

• Reading programming blogs and tutorials
• Taking online classes
• Going to conferences and meetups
• Testing new technologies through side projects

By always growing their skills, full stack developers can handle new challenges.
