This way of thinking helps you to highlight some edge cases in your code, including validation, what places require more tests, and prevent some common attacks. **@przemekhernik** · 22 upvotes > I miss soft skills there 🙈 Backend developers should know how to communicate with frontends, otherwise even with the best technical practices, we can make a mess 😅 **@siinnoxx** · 2 upvotes > I think as a backend developer it is also very important to exchange ideas with colleagues or even friends who work in the same position. For me, it was very good to do this, especially if you are new to the industry and have never written backend code before. It helps you get a better understanding of what a backend should or shouldn't do. And the approach @olehrdk mentioned is perfect for finding things you never thought about before. Of course, this can also be applied to other things. **@tanguychenier** · 2 upvotes > I would add that as a developer, whether you are on backend or frontend, it is important not to neglect the value provided to the customer. > > Domain Driven Design, Behavior Driven Development, and mastery of architectural patterns, such as hexagonal architecture, are fundamentals to have, both as a backend developer and as a developer in general. **@miguelnischor** · 2 upvotes > One more to add: Don't underestimate your customer. Edge case validation are made for creative customers :) ## Similar posts on daily.dev - [Don’t just attend KubeCon \+ CloudNativeCon, Merge Forward your experience\!](https://daily.dev/posts/don-t-just-attend-kubecon-cloudnativecon-merge-forward-your-experience--l0rpp73x8) · CNCF · 1 upvotes · 0 comments - [Announcing H2 2026 KCDs](https://daily.dev/posts/announcing-h2-2026-kcds-m96goajm1) · CNCF · 1 upvotes · 0 comments - [Two months of Open Community Groups](https://daily.dev/posts/two-months-of-open-community-groups-asf52zhbs) · CNCF · 0 upvotes · 0 comments --- Tags: [#career](https://daily.dev/tags/career) [View this post on daily.dev](https://daily.dev/posts/4-best-practices-for-backend-developers-ahqkqzdy3) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"4 Best Practices for Backend Developers","url":"https://daily.dev/posts/4-best-practices-for-backend-developers-ahqkqzdy3","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/4-best-practices-for-backend-developers-ahqkqzdy3"},"datePublished":"2024-04-05T22:10:07.505Z","dateModified":"2024-05-09T08:39:06.345Z","description":"Backend development requires programming language knowledge, frameworks, databases, and security protocols.
