Should I call myself a Developer or an Engineer?”</p> <p>There is a lot of confusion around this, so today, let’s discuss it.</p> <p>First, let’s understand who a developer is and who an engineer is. Then, we will look at a checklist for both.</p> <p>The one that describes what you actually do the most should help you decide what title fits you.</p> <h2> What is a Full Stack Developer? </h2> <p>A Full Stack Developer focuses mainly on building software across the frontend and backend.</p> <p>A developer typically:</p> <ul> <li>Builds user interfaces</li> <li>Develops APIs and backend services</li> <li>Works with databases</li> <li>Integrates third party services</li> <li>Writes and maintains application code</li> <li>Deploys applications</li> </ul> <p>Knowing MERN, PERN, T3, or any other stack can make you a Full Stack Developer. But the technologies you know do not determine whether you are an engineer or developer.</p> <h2> What is a Full Stack Engineer? </h2> <p>A Full Stack Engineer goes beyond building features. They think about how the entire system should work.</p> <p>An engineer considers things such as:</p> <ul> <li>System architecture</li> <li>Scalability</li> <li>Reliability</li> <li>Security</li> <li>Performance</li> <li>Maintainability</li> <li>Testing</li> <li>Infrastructure</li> <li>Deployment</li> </ul> <p>A developer might ask:</p> <p>“How do I build this feature?”</p> <p>An engineer also asks:</p> <p>“How should this system be designed so it continues to work as it grows?”</p> <h2> The Checklist </h2> <p>You may lean toward Full Stack Developer if you mostly:</p> <p>[ ] Build frontend applications<br> [ ] Build backend APIs<br> [ ] Work with databases<br> [ ] Integrate services<br> [ ] Implement product requirements<br> [ ] Focus mainly on application development</p> <p>You may lean toward Full Stack Engineer if you also:</p> <p>[ ] Design system architecture<br> [ ] Think about scalability<br> [ ] Design for reliability<br> [ ] Make infrastructure decisions<br> [ ] Optimize performance<br> [ ] Consider security<br> [ ] Build testing strategies<br> [ ] Make technical trade offs<br> [ ] Design systems for long term maintainability</p> <h2> The Important Part </h2> <p>You do not become an engineer because you learned Kubernetes.</p> <p>You also do not stop being an engineer because you use React.</p> <p><strong>Technologies are tools.</strong></p> <p>The difference is more about how you approach software development and the level of responsibility you take for the systems you build.</p> <p>If you learned MERN and can build applications with it, Full Stack Developer is perfectly valid.</p> <p>If you design, build, deploy, maintain and make architectural decisions about complete systems, Full Stack Engineer may describe your work better.</p> <blockquote> <p><em>Do not choose a title because it sounds better.</em></p> <p><em>Choose the one that accurately represents what you actually do.</em></p> </blockquote> career beginners fullstack softwareengineering
