What does a Full Stack Developer do?

A full stack developer works across React, Node.js, TypeScript to build and maintain systems in software engineering. Day-to-day, you'll be writing code, reviewing pull requests, debugging production issues, and collaborating with product and design teams. It's the kind of role where you need to balance getting things done with doing them well.

The people who do well in this role tend to be strong in PostgreSQL, MongoDB, AWS, but more importantly, they know how to figure out what they don't know. Software Engineering moves fast, and the best full stack developers are the ones who can adapt without needing someone to hand them a playbook every time something changes.

Right now, full stack developer roles pay in the range of $100,000 - $155,000, and most positions are looking for mid-level candidates. It's a competitive field, but companies are hiring. If you've got the right skills and can show real project work, you're in a strong position.

How to get there

Build your foundation in full stack developer

Before anything else, get solid on the fundamentals. For full stack developer roles, that means understanding React and Node.js at a level where you can explain them to someone else. Don't try to learn everything at once. Pick the core topics that show up in every job posting for this role and get genuinely good at them.

Get hands-on with React and Node.js and TypeScript

Reading docs and watching tutorials won't get you hired. You need to actually build things with React and Node.js and TypeScript. Set aside time every week to write code, run experiments, or practice in a real environment. Hiring managers can tell the difference between someone who has used a tool and someone who has just read about it.

Work on real projects

Build something real. A side project, an open-source contribution, or a tool that solves a problem you actually have. The goal is to have something concrete you can talk about in interviews. "I built X, it does Y, and here's what I learned" is worth more than any course certificate.

Get certified in AWS Certified Developer

For full stack developer roles, certifications like AWS Certified Developer - Associate actually carry weight with hiring managers. They won't get you the job on their own, but they signal that you've put in structured effort. If you're choosing between certifications, pick the one you see mentioned most in job postings for roles you want.

Target your first full stack developer role

Most full stack developer positions are mid-level and pay around $100,000 - $155,000. When you're applying, tailor your resume for each job. Use the exact skills and keywords from the posting. Don't be picky about company size or brand name early on. A role where you'll learn fast is more valuable than a prestigious name on your resume.

Grow from here

Once you've got a couple years as a full stack developer, you'll have options. Roles like Principal Engineer, Staff Software Engineer, Software Architect are natural next steps in software engineering. The key is to keep building depth in your specialty while picking up broader skills like leadership, architecture, and cross-team collaboration. Your career path isn't a straight line, but this gives you a strong starting point.

Skills you'll need

These are the skills that show up most often in full stack developer job postings. You don't need all of them on day one, but you should be working toward them.
