If you’re a software developer, you know that not all programming languages are created equal. The right language for the job can make all the difference between an app that runs smoothly and one that crashes every time it gets too much traffic. And although some developers specialize in certain types of languages (like iOS or Android), others need to be comfortable with a wide range of languages because each project is different. So what are the key technical skills every developer should have? Here’s our list:
1. Programming Languages
Programming languages are the building blocks of software. A developer’s knowledge of programming languages can be a make-or-break skill when it comes to landing a job and getting your ideas off the ground.
A good software engineer should be able to speak at least one or two programming languages fluently, but many developers have expertise in more than one language. Some developers focus on one language for all their work, while others learn several languages to choose which language is best suited for each project.
Testing is an important skill that you need to have as a software developer. The software has bugs, which makes testing crucial in ensuring that all of them are found and removed before a product is released to the public. You can test your own code but also other parts of the application, like web pages or mobile apps. There are many types of tests: unit tests that test small pieces of code, integration tests that check whether different components work together, and functional tests that check if everything works from start to finish (the user flow).
3. Development Methodologies
There are several development methodologies or processes for creating software. You’ll most likely encounter the following:
- Agile. This iterative approach to software development emphasizes rapid feedback and adaptability over comprehensive documentation. It encourages collaboration between team members and customers and frequent releases of product versions (or “iterations”). Each iteration produces a working version of the product that users can test before proceeding to the next one.
- Scrum. Similar to agile but with more formal roles, responsibilities, and meetings. It also focuses on short timeframes (typically one month).
- Waterfall methodologies require workflows from start to finish before moving onto another stage of development. This is meant to prevent unfinished work from being passed along between stages until completion happens at some indeterminate point in time far away from where you are now!
4. Database Management
The database management system (DBMS) is part of the application that stores and retrieves data. There are two main types of DBMSs: relational database management systems (RDBMS) and NoSQL databases.
RDBMSs use SQL to query, insert, update, and delete data in a relational structure. These systems were first developed in the 1970s by IBM and have been popular ever since because they are easy to use while still being flexible enough to handle large amounts of information efficiently.
NoSQL databases don’t rely on the concept of relations between tables. Instead, they store data as key/value pairs or documents (JSON-like structures). They emerged around 2000 when web applications became increasingly complex due to increased traffic volumes from mobile devices and new features such as social media integration which require real-time updates from multiple sources at once
These are the technical skills that you need as a software developer
Here are the technical skills that you need to have as a software developer:
- Testing: Software testing is an important part of the development process because it ensures that your product works properly before being released into the wild. There are many different types of tests. Some focus on specific parts of your system, while others look at how well everything works together as a whole.
- Development methodologies: There are several different approaches to creating new software applications. From agile project management techniques like Scrum to waterfall development cycles that involve strict phases for planning out tasks ahead of time and managing risks accordingly throughout each phase until completion..
