Software Engineering 101: An Overview for Beginners

Are you a beginner looking to start a career in software engineering? Or maybe you’re an experienced programmer looking to expand your skills and understanding of software engineering? Here’s your Software Engineering 101 guide, written for both beginners and experts alike. We’ll go over the main components of software engineering, the different kinds of programming languages and frameworks, best resources for getting started, and tips for freelancing and full stack web development.

What is Software Engineering?

Software engineering is the process of designing, developing, and maintaining software. It’s a subset of computer science and involves the use of algorithms, data structures, and software engineering principles. Software engineers specialize in creating the software that run devices and machines, as well as developing software to store and manipulate data.

Software Engineering Components

Software engineering is made up of 7 main components, including:

• Frontend Development
• Backend Development
• APIs
• Database Management
• Servers
• Linux
• Software Security

Let’s look at each of these components in detail.

Frontend Development

Frontend development is the process of creating the user-facing part of a website or application. This includes layout and design (HTML, CSS, and JavaScript), as well as the addition of interactive elements such as widgets and sliders.

Backend Development

Backend development is the process of creating the underlying architecture of a website or application. This includes writing code to store data, process requests, manage user authentication, and more. It is usually written using a programming language such as Python, Node.js, Java, or Php.

APIs

Application Programming Interfaces (APIs) are a set of functions that allow one piece of code to communicate with another. APIs are usually written using a language such as HTTP, JSON, and XML.

Database Management

Database management involves creating, managing, and querying databases. Popular database technologies include MySQL, MongoDB, and PostgreSQL.

Servers

Servers are machines that serve web pages, web applications, and other web services. Common server technologies include Linux, Apache, Nginx, and Digital Ocean.

Linux

Linux is an open source operating system that is used to power servers, desktops, and internet of things devices. It can be used to host websites, run applications, and manage databases. Popular Linux distributions include Ubuntu, Debian, and Red Hat Enterprise Linux.

Software Security

Software security is the process of implementing measures to protect applications and data against security threats. This includes using secure coding principles, using encryption and authentication methods, managing user access, and more.

Programming Languages & Frameworks

The most popular programming languages and frameworks for software engineering are Python, JavaScript, and Java. Other popular technologies include C++, C#, Ruby, and PHP. Understanding these languages and frameworks is key to becoming an effective software engineer.

Tech Stacks

Tech stacks are combinations of technologies used for a certain software. The most popular tech stack for web development, for example, is the MEAN stack (MongoDB, Express.js, Angularjs, and Node.js). Popular frameworks for web development include Django, Flask, and React.

Best Resources for Software Engineering

If you’re just getting started in software engineering, or if you’re an experienced programmer looking to brush up on your skills, there are plenty of free and paid resources available to you. Here are some of the best resources to get started:

• Udemy and Lynda for online courses
• Code academies for in-person courses
• GitHub for open source projects
• Stackoverflow for asking questions and finding answers
• AmazingTechStacks.com for tech stack resources

How to Freelance as a Programmer

Freelancing as a programmer offers you the freedom to choose your own hours and work from anywhere in the world. It’s also a great way to diversify your income and take on projects that interest you. Here are the steps to becoming a freelance programmer:

• Learn the skills you need to be a successful freelancer. This includes coding languages such as Python, HTML, CSS, JavaScript, and databases such as MongoDB. You’ll also need to brush up on web development, design principles, and other necessary skills.
• Develop a portfolio and website to showcase your work. This will help you to attract potential clients.
• Network and build relationships with other freelancers and potential clients. This can be done through LinkedIn, Twitter, and other social media channels.
• Sign up for freelance marketplaces such as Upwork, Freelancer, or Fiverr.
• Create a pricing strategy and bid on projects.
• Deliver high quality work on time.
• Get paid for your work and follow up for feedback.
• Be open to learning new skills and take on more challenging projects to build your reputation and portfolio.
