Overview of the technology industry
The technology industry is a wide and dynamic field that covers everything from AI/ML (artificial intelligence/machine learning), data science, software engineering, app development, web development, cybersecurity, etc. It’s one of the fastest-booming sectors globally and offers huge opportunities for freshers and professionals.
The technology industry has become the backbone of today’s modern society. Because everything and everywhere is tech. Technology powers our business, education, and everything. This guide is created for an enthusiastic software engineer who understands what a software engineer does and understands the difference between a software developer and a software engineer.

What is a Software Engineer?
A software engineer is a good profession for a career. Software engineers do much more than code – they architect systems, solve complex problems, design systems, team leads, and ensure software runs efficiently and securely.
They focus on creating reliable and scalable software systems that solve real-world problems. A software engineer’s role is software design, web/app development, testing, and maintenance.
What is a Software Developer?
A software developer is focused on writing and implementing code. They work on a smaller module of the system or software, whereas a software engineer manages the whole software, system architecture, and engineering.
Distinguish Between Software Developer and Software Engineer?
| Category | Software Developer | Software Engineer |
| Focus | Coding & Building features | Engineering systems & solving architectural issues |
| Scope | Frequently individual modules | Entire applications or system architecture |
| Collaboration | With designers, testers | With project managers, stakeholders, and QA teams |
| Long-Term Thinking | Less focus | Strong focus on scalability, maintainability |
What Does a Software Engineer Do?
A software engineer has many responsibilities depending on the projects. They have designed and developed the System architecture for the software, web application, mobile applications, etc. System architecture design plays a major role before developing any software or application. They solve the problems using code and logic. They have worked with the software development life cycle phases/models, developing the software. They follow software development life cycles, such as agile methodologies and the waterfall model.
They are collaborating with cross-functional teams, like UI/UX designers teams, Graphic designers teams, Testing teams, Web Development teams, and app development teams etc. There are major roles after developing software, which include deploying applications/software and maintaining them. They are participating in the software development life cycle to develop successfully. They use agile, scrum workflows, etc.
Understanding the role & responsibilities of a software engineer
A software developer also has many responsibilities. After they got the workflow or system architecture, or requirements from the product engineer, they started work on development. They have built websites, apps, and a deployment etc.
What to Study to Become a Software Engineer Or Software Developer?
If you’re thinking about what to study to become a software developer, let’s check out here step-by-step guide:

Software Development Life Cycle Phases/Models?
What is SDLC (Software Development Life Cycle)?
The Software Development Life Cycle (SDLC) is a fast and easy way used by software engineers and developers for Software design, development, testing, and maintenance. It is a major step or phase in developing software.
Phases of Software Development Life Cycle
1. Requirement Collection
- This is the first step in SDLC, and you understand what the user wants for their software:
- Who will use this software
- What is the actual problem, and what is the best and easiest way to solve this problem?
- Which type of user is based on or who uses this software?
2. Design
- Let’s time to plan the structure or design for your software.
- Create a design, blueprints, and architecture diagrams.
- This step helps to clear and detailed design for the developers and guides them while developing software.
3. Implementation (Coding/Development)
- This is real or actual work of the software and coding phase.
- In this step, developers write code for software using different programming languages and frameworks like Python, Java, JavaScript, React.js, Next.js, Angular.js, Django, etc.
- The developer team follows the design documentation and builds the projects
- The main goal of this project is to convert the design into a working product.
4. Testing
- It’s time to test everything, which means testing logic.
- Find bugs or errors and solve them.
- Test whether logic and software work as expected or not.
- Test the user experience, responsiveness, performance, and security of the software.
- The main goal of this phase is to software is reliable, secure, user-friendly, and bug-free.
5. Deployment
- After the software passes all Software life cycle tests, its step is very important for developers and related to users.
- It can be deployed on your software live server or distributed via app stores.
- The product is ready for real users to use this software or product, and make the software available for all users.
6. Maintenance
- After release, software needs updates, changes in requirements, bug fixing, and any other queries.
- Sometimes users require new features.
- When huge traffic comes to your software or server that the server goes down issue or sometimes the server crashes that time you need to improve performance.
- When users report an issue or bug, developers solve the issue or bug in maintenance.
- The main goal of this phase is to keep the software working properly and smoothly without any trouble.
Some Examples of Software Development Life Cycle Models
- Waterfall model
- Easy to use or manage
- Best for small-scale and simple projects.
- Agile Model
- It’s used for fast delivery.
- It’s ideal for changing requirements.
- Currently, most companies prefer this SDLC Model
- DevOps Model
- This model combines development(Dev) and operations(Ops).
- This model is mainly focused on automation, testing, continuous delivery, and monitoring.
- It’s very useful when you’re working in a team. It encourages collaboration between all teams.
- It is great for projects that need speed, security, and efficiency.
